Chapter 1 PSTN Basic Services

The basic service of Public Switched Telephone Network (PSTN) refers to the basic call connection functions provided by the switch, including inter-office call, local call, national toll call, international toll call, tandem call and others. The following is a brief description of all kinds of calls.

I. Intra-office call

The intra-office call is the call connection initiated by two subscribers in the same office. In the case of the C&C08 EV switching system, it is a call connection between two Switching Module (SM)s managed by one Administration Module (AM)/Communication Module (CM) or inside an SM. Calls of this kind do not occupy such resources as trunk.

II. Local call

The C&C08 EV switching system can provide call connections between local network subscribers (including municipal subscribers, rural subscribers and county subscribers) as well as call connections between remote module subscribers and subscriber concentrator subscribers.

III. National toll call

The C&C08 EV switching system can provide the subscriber with the outgoing service of automatic national distance dialing and the automatic incoming service of national toll. It is the call connection realized by selecting routes and sub-routes and occupying trunk resources.

IV. International toll call

International toll call is of two types: International automatic call connections and International semi-automatic connections. The C&C08 EV switching system can provide the subscriber with the function of international toll call, including the outgoing service of automatic international direct distance dialing and the automatic incoming service of international toll.

V. Tandem call

The C&C08 EV switching system can provide the trunk-tandem forwarding service of national toll and international toll.

Chapter 2 Flexible Implementation of PSTN Supplementary Services

Different countries and different regions may have different requirements for the same PSTN supplementary services, such as priority and compatibility between different services. The C&C08 EV Digital SPC Switching System adopts the following methods to solve the problems.

2.1 Service Syntax Analysis

For the same PSTN supplementary services, the standards and telecommunication operators of the different countries and regions may have different demands on dialing. Now take Abbreviated Dialing for example. In different countries and regions, the subscriber registration and the dialing mode of abbreviated dialing service may be different. By adopting external data to describe the input format of supplementary service, C&C08 EV Digital SPC Switching System specifies the service input format according to the requirement of the different countries and regions, thus enabling the different input formats of the same service in multiple countries and regions.

2.2 Service Priority

For the same PSTN supplementary service, the standards and telecommunication operators of the different countries and regions may have different demands on priority. Now take the priority between Call Forwarding Unconditional service and Do-not-Disturb Service for example. It may be required by some regions that the incoming calls are forwarded unconditionally when a subscriber is registered with both Do-not-Disturb Service and Call Forwarding Unconditional service; while in other regions, the Do-not-Disturb Service may have priority in such a case. By adopting the external data to describe the priority of the conflicting supplementary services, The C&C08 EV Digital SPC Switching System specifies the priority of different services according to the requirement of different countries and regions, thus enabling different services with different priorities in multiple countries and regions.

2.3 Service Compatibility

For the same PSTN supplementary services, the standards and telecommunication operators of the different countries and regions may have different demands on compatibility. Now take the priority between the Call Forwarding Unconditional service

Operation Manual Supplementary Services Volume C&C08 EV Digital SPC Switching System


2-2

and the Do-not-Disturb Service for example. In some counties and regions, such as China, these two services are not compatible. Therefore, the subscriber registered with the Call Forwarding Unconditional service cannot register the Do-not-Disturb Service, and conversely is the same case. However, other countries or regions may want to distinguish them through service priority. By adopting the external data to describe the compatibility of the conflicting supplementary services, The C&C08 EV Digital SPC Switching System specifies the compatibility of different services according to the requirement of the different countries and regions, thus enabling different services with different compatiblities in multiple countries and regions.

Chapter 3 PSTN Supplementary Services

Note: Before using a service, carry out the ADD CNACLD command to add the service prefix. Otherwise, the service will be unavailable. Both the administrator and authorized subscriber can activate and deactivate a service. That is, the administrator can carry out the REG NSV command to activate a service and the RMV NSV command to deactivate a service, and an authorized subscriber can activate and deactivate a service on a telephone through dialing the access code. Only the last setting is effective.

3.1 180 Service

I. Meaning

The 180 service is for the inquiry of call charge. A subscriber can know the charge of his last call and his total call charge through dialing a prefix after the completion of a call.

The 180 service is available only for subscribers of an end office and only ST, DSL and V5ST subscribers can use it.

II. Data configuration

z Configuring the prefix

Carry out the ADD CNACLD command to configure the prefix of the 180 service. Set the [SERVICE CATEGORY] parameter to "supplementary service" and the [SERVICE ATTRIBUTE] parameter to "DCHGI(query charging information by DTMF)". The [SERVICE SEQUENCE NUMBER] parameter ranges from 0 to 5. If this parameter is set to a value greater than 5, subscribers will hear the busy tone after dialing the prefix. The values 0~5 stand for the following meanings:

0: Announces the meter count of the last call of a subscriber.

1: Announces the total meter count of a subscriber.

2: Announces the meter count of the last call and the total meter count of a subscriber (including 0 and 1).


3-2

3: Announces the charge of the last call of a subscriber.

4: Announces the total call charge of a subscriber.

5: Announces the charge of the last call and total call charge of a subscriber (including 3 and 4).

The default data has configured the prefixes 1800~1805 to send the above six voice announcements respectively.

z Setting the maximum number of service subscribers

Carry out the MOD SMP/LST MDU command to set the maximum number of tuples of the 180 service dynamic table. The maximum number of tuples of the table determines the maximum number of subscribers who can successfully use the 180 service. Set the [PARAMETER] to "maximum number of 180 service subscribers". The default value is 200.

After the modification of the maximum number of tuples, format the data and load it, then the modification takes effect. Therefore, it is recommended to set a proper maximum number of tuples for the table according to actual requirements at first so as to avoid reloading the system.

z Backing up data

Carry out the BKP NSV command to back up the 180 service data in the active MPU/SPC board to the BAM. After resetting or re-startup, the host will automatically load the 180 service data from the BAM to the foreground. Set the [SUPPLEMENTARY SERVICE ID] parameter to "play charge info".

Bit 10 of the software parameter P55 controls whether the switch supports real-time backup.

=1: Not support (default value). The BAM will back up supplementary service data at specified intervals.

=0: Support

z Configuring voice announcement data

When voice channels are adequate, the SM uses the SIG board to play voice announcements and supports simultaneous voice announcement of 20 channels, while the SPM supports simultaneous voice announcement of 200 channels.

When no voice channel is available for a call, the switch first plays a voice announcement like "The line is busy now. Please try again later".

Carry out the MOD SIGSET command to modify the voice configuration data of some supplementary services in the SIG/SPD board. The 180-service uses the signal indexes 95 and 96 (that is, TID) whose [SEND SOUND TYPE] parameter is set to "synchronous signal". By default, each index has three voice files as follows.


3-3

The voice files whose signal index is 95 are for the announcements of meter counts of calls. Its three files are FFFFF85F, FFFFF880 and FFFFF881.

FFFFF85F is the leading voice announcement and the switch plays it each time. If it is not needed, record a one-second silence.

FFFFF880 contains the announcement of the meter count of the last call of a subscriber. Record it like "Your last call METER count is".

FFFFF881 contains the announcement of the total meter count of a subscriber. Record it like "Your total call METER count is".

The voice files whose signal index is 96 are for the announcements of call charges. Its three files are FFFFF860, FFFFF882 and FFFFF883.

FFFFF860 is the leading voice announcement and the switch plays it each time. If it is not needed, record a one-second silence.

FFFFF882 contains the announcement of the charge of the last call of a subscriber. Record it like "Your last call FEE cost is".

FFFFF883 contains the announcement of the total call charge of a subscriber. Record it like "Your total call FEE cost is".

III. Operations

To offer the 180 service for a subscriber, just carry out the MOD NSR command and set the [SUPPLEMENTARY SERVICE] parameter to "play charging info".

After the operator adds the service authority for a subscriber and online sends the subscriber data to the host, the switch will automatically add a record to the 180-service dynamic table and set its value to 0. Therefore, before the addition of the 180 service authority for a subscriber, first check the maximum number of tuples of the 180-service dynamic table. Otherwise, the addition of 180 service data will fail.

The cancellation of the 180 service authority of a subscriber will cause the switch to delete the corresponding data in the 180-service dynamic table. After the deletion, the original data cannot be recovered. If to re-add the service authority for the subscriber, all the service data of the subscriber will be initialized to 0. Therefore, take care when canceling the 180 service authority of a subscriber.

IV. Related commands

z LST NSVUSER

You can carry out the LST NSVUSER command to list the total number of the 180 service subscribers of an office and their detailed information. Set the [SUPPLEMENTARY SERVICE] parameter to "play charge info".


3-4

z DSP NSV

You can carry out the DSP NSV command to view the records in the backed-up 180-service dynamic table on the background. Set the [SUPPLEMENTARY SERVICE] parameter to "play charge info".

V. Charge accumulation

The 180-service dynamic table accumulates only the charges of metering bills and detailed bills. The following cases are possible.

z Calls for which the switch generates only detailed bills

In this case, the switch refreshes only the accumulated charges in the 180-service dynamic table and will not refresh corresponding meters.

z Calls for which the switch only refreshes corresponding metering bills

In this case, the switch refreshes not only the accumulated charges in the 180-service dynamic table but also corresponding meters. The charges are calculated directly according to the tariffs of the meters.

z Calls for which the switch generates not only detailed bills but also refreshes corresponding metering bills

In this case, the 180-service dynamic table refreshes the meter and charge only one time and will not add the charge again to the total charge. It is similar to the above case. Take care not to add the charge again to the 180-service dynamic table.

z Calls for which the switch generates no bill

In this case, according to current processing mode, the switch will not refresh the 180-service data, that is, neglect the charge of the call and have no change of the 180-service data.

Note: z There is no special supplementary service charging method for the 180 service. Use a common

charging method to charge it. z The 180 service records only the charge of the charging mode that the calling or called party is

charged. For calls involving hooking, the switch considers only the charges of the subscriber in these bills.


3-5

3.2 Abbreviated Dialing Service

I. Meaning

To facilitate calling, the subscribers can set a short code (2 digits) to represent a number. This number can be local number, national toll number, or international toll number, and the latter two shall include the national or international prefix. Each subscriber can have several abbreviated numbers.

II. Setting conditions

The subscriber has the "abbreviated dialing" authority (you can use the command: ADD ST or MOD ST to set it), and the service has been registered in the "supplementary service".

III. Operation

Suppose:

A Service subscriber

MN 2-digit abbreviated number (0


3-6

Operation Expected result

Subscriber A dials #51*MN# Subscriber A hears the acknowledgement tone of the successful service cancellation

Subscriber A hangs up Service cancelled

IV. Example

Suppose the number of Subscriber B is 8883850 (that is, "TN" is 8883850), and its abbreviated number "MN" is 12 (0


3-7

Note: z This service does not conflict with other supplementary services. z If the same MN has been registered for several times, only the number registered for the last time is

valid. z This service can also abbreviate the called number to 1 digit, using the same registration, operation

and cancellation method.

3.3 Absent Subscriber Service

I. Meaning

If a subscriber has "absent subscriber service" registered, when dialing the number of the subscriber (the callee), the caller will hear the absent subscriber service tone.


The subscriber has the "absent subscriber service" authority (you can use the command ADD ST or MOD ST to set it).

III. Operation

Suppose:

A Service subscriber.

1) Service registration


Subscriber A hooks off Subscriber A hears the dialing tone

Subscriber A dials *50# (on DTMF phone) or 150 (on Pulse phone)

Subscriber A hears the acknowledgement tone of the successful service registration

Subscriber A hangs up Service registered

2) Service operation

When a subscriber dials the number of Subscriber A, he/she will hear the absent subscriber service tone.

3) Service cancellation




3-8


Subscriber A dials #50# (on DTMF phone) or 151150 (on Pulse phone)

Subscriber A hears the acknowledgement tone of the successful service cancellation

Subscriber A hangs up Service cancelled

Note: z The subscriber cannot simultaneously apply for absent service and call forwarding busy. z The subscriber cannot simultaneously apply for absent service and call forwarding unconditional. z The subscriber cannot simultaneously apply for absent service and call forwarding no reply. z When applying for the absent subscriber service, the subscriber cannot use the malicious call

identification service. z When the absent subscriber service is registered, the subscriber will not have the call waiting

function. z If a subscriber has activated both the absent service and do not disturb service, the switch gives

priority to the do not disturb service. z This service cannot be used simultaneously along with the call back on busy service. z The subscriber cannot simultaneously apply for absent service and wake up service.

3.4 Automatic Call Memory (ACM)

I. Meaning

With the automatic call memory service, the switch saves the caller number of the last call that the service subscriber didn't answer. Later, when the subscriber uses the phone, he/she will know the last phone number who calls him/her through dialing a special service code. Moreover, the switch offers the callback function.

The ACM service is available on both the SM and SPM. For the SM, it is the SPT board or SPM voice resource that sends voice announcements (for related data configuration, refer to the following part "Data configuration"). For the SPM, it is the SPD board that sends voice announcements.

II. Data configuration

z Adding the service prefix

ADD CNACLD: PFX=K'*92#, CSTP=IN, CSA=LCO, MINL=4, MAXL=4, CHSC=65535;

Configure a call prefix "*92#". Set the [SERVICE CATEGORY] parameter to "intelligent service" and the [SERVICE ATTRIBUTE] parameter to "intra-office".


3-9

z Adding an IN access code and DP data

ADD ACCODE: CODE=K'*92#, LEN=4;

ADD TDPCFG: DPNO=3, CSC=0, CODE=K'*92#, SKEY=500;

Add the access code of the prefix "*92#" and configure the TDP configuration data to trigger the PPS. Set the [SERVICE KEY] parameter to "500" (standing for the ACM service).

z Adding resource capability

ADD SSPSRC: SKEY=500, MN=255;

"255" means that all modules have resource capabilities for the service.

z Adding resource search data

ADD SRCSRH: MDU=1, SRC=BRD, STATE=USE, SRH=FIX, MDU1=2, MDU2=3, MDU3=4, MDU4=5;

When a module has no resource, it can apply to other modules in the office for resources after the configuration of the resource search data. It is recommended to set the search mode to "Fixed search". For recommended search sequence for the modules in an office, refer to the following table.

Table 3-1 Recommended search sequence for modules in an office

Module No.

The 1st search module

The 2nd search module

The 3rd search module

The 4th search module

1 2 3 4 5

2 3 4 5 1

3 4 5 1 2

4 5 1 2 3

5 1 2 3 4

Note: For the SM, set the inter-module communication rate to 512 kbit/s. For the SPM, set the inter-module communication rate to 2 Mbit/s.

z Adding language index

ADD INLNG: LI=1, LT1=64;

Configure the language index 1 to stand for English.

z Setting software parameters


3-10

MOD SFP: ID=P127, VAL="0xefff";

The command means that the switch will support the card service of the ISP mode, that is, PPS.

MOD SFP: ID=P56, VAL="fff7";

The switch will immediately back up the ACM dynamic data to the BAM after refreshing.

MOD SFP: ID=P56, VAL="ffef";

The switch will refresh the ACM information unconditionally when overriding the number restriction and number incomplete.

z Adding the preselection access code

The ACM service uses the first three Preselection access code records by default. Recording of voice files should be consistent with the data set here.

ADD PRECODE: IDX=0, ACD=K'001, CN="TELECOM";

ADD PRECODE: IDX=1, ACD=K'002, CN="ORIBITEL";

ADD PRECODE: IDX=2, ACD=K'003, CN="ETB";

"CN" stands for the name of a carrier.

z Centrex subscriber using the ACM service

Centrex subscribers can also use the ACM service but the switch cannot record Centrex extension numbers. The prefix "*92#" cannot be used within a Centrex group because it is used to trigger the IN service. To use the ACM service, therefore, Centrex subscribers need first dial the out-group prefix then the prefix "*92#", or operators add the prefix "*92#" for a Centrex group. The following configuration is only for reference.

1) Add an intra-group prefix "*92#"

ADD CXPFX: CXG=0, PFX=K'*92#, CSA=ALLSRVC, MINL=4, MAXL=4;

2) Add a number change record to insert the prefix "0"

ADD DNC: DCX=1, DCT=INS, ND=K'0;

3) Add a Centrex prefix special processing record to insert the out-group prefix before the prefix "*92#" and the switch will reanalyze the number

ADD CXPFXPRO: CXG=0, PFX=K'*92#, CSC=0, DDC=YES, DDCX=1, RAF=YES;

z Setting the maximum number of service subscribers

Carry out the MOD SMP command to set the maximum number of tuples of the ACM service dynamic table. The maximum number of tuples of the table determines the maximum number of subscribers who can successfully use the ACM service in one


3-11

module. Set the [PARAMETER] to "maximum number of ACM service subscribers". The default value is 100.

After the modification of the maximum number of tuples, format the data and load it, then the modification takes effect.

z Backing up data

Carry out the BKP NSV command to back up the ACM service data in the active MPU/SPC board to the BAM. After resetting or re-startup, the host will automatically load the ACM service data from the BAM to the foreground. Set the [SUPPLEMENTARY SERVICE ID] parameter to "ACMS".

z Setting the supplementary service fixed charging mode

ADD NSFIXCHG: NS=ACMU, RCHS=0, LOAD=ALLSVR, CHGT=DETAIL;

Each time a subscriber uses the ACM service, the switch will generate a supplementary service bill (detailed bill).

ADD NSFIXCHG: NS=ACMU, RCHS=0, LOAD=ALLSVR, CHGT=PLSACC, MID=METER1;

Use the meter 1 to count the times that a subscriber uses the ACM service.

III. Operations

To use the ACM service, a subscriber doesn't need to register it as long as he has the service authority. New service subscribers use the default ACM data whose call attribute is "National toll" and caller number is "99999999".

Suppose Subscriber B calls Subscriber A. Regardless of whether Subscriber A answers the call, the switch will record the attribute and caller number of the call as the ACM information of Subscriber A. If Subscriber B's number is restricted from displaying or is incomplete, the switch will use the default data to refresh the ACM information.

After Subscriber A dials a special service code (for example, "*92#"), the switch will announce the number of Subscriber B. Then there are three possible cases.

z If the call from Subscriber B is an intra-office call or a local call, Subscriber A will hear an announcement like "To make a callback, please press 1". If Subscriber A presses 1, the switch will call Subscriber B. If the call from Subscriber B is a national or international long distance call, the switch will ask Subscriber A to select a toll carrier. After Subscriber A selects one, the switch will call Subscriber B through the selected carrier.

z After the voice announcements, if Subscriber A dials a wrong number, the switch will send an announcement like "The number you dialed is not correct, please dial again". If Subscriber A dials a wrong number again, the switch will send the


3-12

announcement again. For the third time, the switch will send an announcement like "Sorry, you have surpassed the maximum times for interaction. Thank you for using, bye" and then send busy tone.

z If Subscriber A dials no number after the prompt of selecting a carrier for five seconds, the switch will send busy tone directly.

The cancellation of the ACM service authority of a subscriber will cause the switch to delete the corresponding data in the ACM-service dynamic table. After the deletion, the original data cannot be recovered. If you re-add the service authority for the subscriber, all the service data of the subscriber will be initialized to the default data. Therefore, take care when canceling the ACM service authority of a subscriber.

IV. Related commands

z LST NSVUSER

You can carry out the LST NSVUSER command to list the total number of the ACM service subscribers of an office and their detailed information.

z DSP NSV

You can carry out the DSP NSV command to view the records in the backed-up ACM dynamic table on the background. Set the [SUPPLEMENTARY SERVICE ID] parameter to "ACMS".

Note: The ACM service is available only for the subscribers of a non-SSP end office. Only ST, DSL, and V5ST subscribers can use this service.

V. Tunisian mode

The above mode is the Colombian mode.

In the Tunisian mode, suppose there is an ordinary subscriber A in the office A who has activated the ACM service, and there is a subscriber B (belonging to the office A or other office) who has called the subscriber A but received no answer. After dialing a special supplementary service prefix, the subscriber A will be connected to the subscriber who is the last one to call him but receive no answer (if there are multiple subscribers who make calls to the subscriber A but receive no answer, the switch connects the subscriber A only to the last time subscriber).

The differences between the Colombian mode and the Tunisian mode are as follows:

z In the Tunisian mode, the switch records the caller number of a call only when the service subscriber does not answer the call.


3-13

z In the Tunisian mode, the switch directly makes a callback and gives no prompt after the service subscriber dials the ACM service number.

z The Tunisian mode requires no configuration of the IN service data and related voice files

Bit 5 of the Call Testing Parameter 4 (P56) controls whether the ACM service is of the Colombian mode or of the Tunisian mode. By default, it is of the Colombian mode.

To use the ACM service in the Tunisian mode, configure the following data:

z Modify Bit 5 of the software parameter P56 to "0".

MOD SFP: ID=P56, VAL="FFDF";

z Add the prefix data and set the [SERVICE ATTRIBUTE] parameter to "Use automatic call memory by DTMF".

ADD CNACLD: PFX=K'*92#, CSTP=NEW, CSA=DACMS, MINL=4, MAXL=4, CHSC=65535;

3.5 Advice of Charge (AOCE)

I. Meaning

The registered subscriber initiates a call. After the conversation, the switch sends a prompt ringing tone to the subscriber, meanwhile the bill information of this conversation is displayed on the phone set.


The subscriber has the "AOC" authority (you can use the command ADD ST or MOD ST to set it), and the service has been registered in the "supplementary service". If a subscriber wants to use this service, he must select the phone set supporting the service.

III. Operation

Suppose:


B Ordinary subscriber




Subscriber A dials *88# Subscriber A hears the acknowledgement tone of successful registration of the service


3-14






Subscriber A dials Bs number Subscriber A hears the ring back tone and Subscriber B hears ringing tone

Subscriber B hooks off Subscriber A talks with Subscriber B

Subscriber A hangs up Subscriber A hears the ringing tone and the fee of this conversation is displayed on As phone set.




Subscriber A dials #88# Subscriber A hears the acknowledgement tone of successful cancellation of the service

Subscriber A hangs up Service canceled

IV. Example

Suppose Subscriber B's number is 8883010, the operation process is as follows:




Subscriber A dials *88# Subscriber A hears the acknowledgement tone of successful registration of the service





Subscriber A dials 8883010 Subscriber A hears the ring back tone and Subscriber B hears ringing tone



3-15


Subscriber A hangs up Subscriber A hears the ringing tone and the fee of this conversation is displayed on As phone set.




Subscriber A dials #88# Subscriber A hears the acknowledgement tone of successful cancellation of the service


Note: z This service is not applicable to the pulse telephone. z Bit 2 of the CCB internal parameter 4 determines whether registry is needed before using this

service. If it is set to 1, no registry is needed; if it is set to 0, registry is compulsory. z AOC service includes AOCS (Advice Of Charge at the Start of a call), AOCD (Advice Of Charge

during a call) and AOCE (Advice Of Charge at the End of a call). In which, AOCS and AOCD are available to ISDN subscriber.

3.6 Assigned Pickup Call in Group

I. Meaning

To intercept the calls to a subscriber, you can dial the service code and the number of the subscriber.


The subscriber has the "assigned pickup call in group" authority (you can use the command ADD ST or MOD ST to set it), and the service has been registered in the "supplementary service".

III. Operation

If Subscriber A uses the DTMF phone that is set to the assigned pickup. Subscriber B is in the same assigned pickup group as Subscriber A in the office, whose number is PQABCD. Subscriber C is a call-originating subscriber.



3-16

Apply to the Telecommunication Office for it.



Subscriber C hooks off Subscriber C hears the dialing tone

Subscriber C dials the number of Subscriber B

Subscriber C hears the ring back tone, and Subscriber B hears the ringing tone


Subscriber A dials *11*PQABCD# Subscriber B stop hearing the ringing tone, and Subscriber A talks with Subscriber C

Subscribers A and C hang up Service ended



IV. Example

If Subscriber B's number is 8883850, the operation process is as follows:





Subscriber C hooks off Subscriber C hears the dialing tone

Subscriber C dials 8883850 Subscriber C hears the ring back tone, and Subscriber B hears the ringing tone


Subscriber A dials *11*8883850# Subscriber B stop hearing the ringing tone, and Subscriber A talks with Subscriber C

Subscribers A and C hang up Service ended



Note: This service requires that pickup party and service subscriber should be set in the same pickup group.


3-17

3.7 Assigned Trunk Line Call

I. Meaning

Through this service, calls can be made on the designated trunk lines, Internal Digital Trunk (IDT) lines and Local Optical Interface Board (OPT) lines.


The subscriber is a test user (you can use the command ADD ST or MOD ST to set it), and the service has been registered in the "service attribute" of command ADD CNACLD.

III. Operation

Suppose:

A Test user

MMM Module number

N Designated line type (value ranging between 0~2: 0-Trunk line, 1-IDT line, 2-OPT line)

TTTTT Circuit No.

PQRABCD Subscriber B's number






Subscriber A dials *66*MMM*N*TTTTT#PQRABCD

The call is connected to Subscriber B through the designated circuit

Subscriber B hears the ringing


Subscriber A or B hangs up Service ended




3-18

IV. Example

Suppose test user A wants to originate a call to Subscriber B through trunk circuit 10 of module 1 and Bs number is 8883850, the operation process is as follows:






Subscriber A dials *66*001*0*00010#8883850

The call is connected to Subscriber B through the trunk circuit 10 of module 1. Subscriber Bs phone rings.

Subscriber B hooks off Subscriber A talks with Subscriber B.

A or B hooks up Service ended



Note: z This service is for test user only. If the current area is Hong Kong, the operator can also use this

service. z The pulse phone set cannot use this service. z This service needs no registration or cancellation.

3.8 Authentication Service

I. Meaning

Authentication service mentioned here is only for authenticating incoming trunk caller by means of number length authentication, call barring or caller attribute modification in the unit of trunk group. Different authentication modes can be adopted based on different caller categories, and different authentication modes can also be set for different caller numbers and address attributes. This service is used in tandem office to meet the requirement of large-capacity trunk authentication. In case of configuring authentication data on Internet Service Process board (ISP), a maximum of 500,000 pieces of data can be configured.


3-19


In order to implement trunk authentication, the outgoing trunk side of the opposite office is required to send caller number automatically. If the outgoing trunk does not do so, the incoming trunk should be set to request outgoing trunk for the caller number; otherwise, authentication cannot be done normally.

III. Operation

The operator uses ADD CLRDSG to set authentication modes for different callers, and uses ADD TGDSG to specify the corresponding authentication group numbers for various incoming caller categories.

IV. Example

z Add caller authentication function for ISP:

ADD ISPFUNC: FCF=CLRDSP, BG=3;

z Set to use incoming trunk group 10, and the length of caller number ranging from 7 to 10. The calls out of the length range will be rejected.

Step one: add a discrimination mode for a discrimination group number - number length discrimination

ADD CLRDSG: DSP=10, CLI=K'654, DAI=UDN, FUNC=DSG, MIN=7, MAX=10;

Step two: set a discrimination group number for the trunk group

ADD TGDSG: TG=10, CCAT=254, DSG=10;


3-20

Note: z The field "CALLER CATEGORY" in ADD TGDSG supports the wildcard character 254. When 254 is

entered, all caller categories will be matched. z The fields "REQUEST CALLER NUMBER" and "CAN REQUEST CALLER NUMBER" must be set to

"TRUE" first before setting of discrimination group number for trunk group by using ADD TGDSG, so as to further ensure that the opposite office will send the caller number; otherwise, caller authentication cannot be carried out.

z Due to the limit of table capacity of the host program and data setting mode, wildcard character field will not be supported if discrimination data ADD CLRDSG is not set on ISP, while if the data is set on ISP, both discrimination group number and caller number support wildcard character field. Discrimination group number supports wildcard character discrimination group 65534, and caller number supports 16-e wildcard character (eeeeeeeeeeeeeeee).

z The function codes of the discrimination group are described as follows: a) REJECT CALL: reject incoming calls directly. b) CALLER NUMBER DISCRIMINATION: number length discrimination; restrict the length of caller number of the opposite office. If the caller number length exceeds the specified range, the call will be rejected. c) Modify caller attribute: modify some attributes of the caller without affecting incoming calls. The caller attributes that can be modified are: call source code, billing source code, subscriber call barring group number, caller category and caller number change of the incoming trunk implemented through caller number change index. d) Caller number discrimination and modify caller attribute: b) combination with c).

3.9 Black and White Lists

I. Meaning

Black and white list is subject to call barring service, that is, caller and callee are set with a group number identifier respectively (call barring group number), to allow or prohibit a call by configuring the call barring relations between calling group number and called group number. Caller and callee mentioned here not only limit to phone subscribers, but include various trunk subscribers. Therefore, different call barring group numbers can be specified for different subscribers in Common/ISDN phone set or trunk group.


Null.


3-21

III. Operation

The commands related to call barring group number are as follows:

z ADD/MOD ST, ADD /MOD DSL, ADD /MOD V5ST and ADD /MOD V5DSL: setting/modifying call barring group numbers of subscribers of various phone sets;

z ADD /MOD N7TG and ADD /MOD N1TG: setting/modifying the default call barring group numbers of subscribers of CSS7 or Channel Associated Signaling (CAS) trunk;

z ADD /MOD CLRDSG: modifying call barring group numbers according to different calling numbers of the incoming trunk group through caller authentication, so as to specify different call barring group numbers for different calling numbers and for the incoming trunk to implement call barring by black and white lists based on calling numbers. However, a precondition must be provided that the outgoing trunk of the opposite office should send calling numbers.

Among the above commands, only CALL BARRING GROUP is relevant to call barring group numbers.

z ADD CLDGRP: setting called restriction group number. Called number can be only the prefix of a number or a complete number, and the system identifies called number field by the maximum match. For example, if two called numbers 654 and 6540001 are in a table, when a subscriber dials 6540001, the called number 6540001 will be matched instead of 654.

z SET GAC: setting whether call barring is allowed between groups.

IV. Example

z Suppose there is a calling number 6540001 and a called number 7770001, and it is required to set call barring that 6540001 can't call 7770001 through the black and white lists function, the following data should be set:

MOD ST: D=K'6540001, LMTGRP=1;

ADD CLDGRP: CLD=K'7770001, GRPT=OG, GRP=2;

SET GAC: SRG=1, DRG=2, CI=CDIS;

z Suppose there is an incoming trunk group 10 and a called number 77700001, and it is required that a non-local subscriber calls the callee from the trunk group 10:

MOD N7TG: TG=10, LMTGRP=1; (CCS7 trunk group)

(MOD N1TG: TG=10, LMTGRP=1;) (CAS trunk group)

ADD CLDGRP: CLD=K'7770001, GRPT=OG, GRP=2;


3-22

SET GAC: SRG=1, DRG=2, CI=CDIS;

Note: z The call barring group numbers range from 0 to 65535, and several special group numbers are

described as follows: 65535 --- indicating void call barring group number, that is, subscriber is not subject to any call barring group number; 60001 --- black list call barring group number. The subscribers subject to black list can only call subscribers in white list; 60002 --- white list call barring group number. The subscribers subject to white list can call the subscribers of all other call barring group numbers; 65534 --- call barring group number wildcard character. Note not to set call barring group number as wildcard character for subscribers, however, wildcard character 65534 can be specified as the call barring group number during setting of inter-group call barring table by SET GAC. z Before specifying call barring group number for a subscriber, you should use SET GAC to finish the

settings for newly-added group numbers and other numbers. z Be careful in using the wildcard character: if unnecessary, it is better not to use wildcard character to

set data restriction in command SET GAC, otherwise, it may lead to the failure of most calls.

3.10 Block the Blocker

This service is a terminating feature. It enables a subscriber to reject incoming calls carried no Calling Line Identification (CLI) information or the CLI information is not allowed to be displayed to the subscriber.

The rejected calls will be routed to a denial announcement or a pre-defined tone will be returned to the caller for advising that the callee does not wish to receive anonymous call.

When this feature is activated in the subscribers line, normal call termination process will be provided to those incoming calls meeting with the following conditions.

z Calls carry CLI information and presentation of the CLI information is allowed; z International call; z Calls with NI = 1.

If the calls do not meet the conditions, they will be routed to an announcement or a pre-defined tone will be returned to the callers.

Law Analog Subscriber Line Board (DEL) subscribers, Centrex subscribers, Integrated Services Digital Network (ISDN) Basic Rate Access (BRA) subscribers and


3-23

pilot or auxiliary subscribers of any hunting group can activate/deactivate this feature by pressing the access code *76 / #76.

For B number of Duplex Ringing subscriber, the activation and deactivation codes are *#*76 / *##76.

3.11 Booking Call

I. Meaning

This service enables the subscriber to automatically originate calls to the called number assigned beforehand when the pre-set time arrives.


The subscriber has the "booking call" authority (you can use the command ADD ST or MOD ST to set it), and the service has been registered in the "supplementary service".

III. Operation

Suppose:

A Service subscriber with the "booking call" authority

HH Hours set by the subscriber (00~23)

MM Minutes set by the subscriber (00~59)

PQABCD Called number




Subscriber A dials *67*HHMM*PQABCD# (on DTMF phone) or 167HHMMPQABCD (on Pulse phone)

Subscriber A hears the acknowledgement tone of successful registration of the service



When the pre-set time arrives, the switch will first of all send the ringing tone to Subscriber A. When Subscriber A hooks off, the switch will automatically originate a call to the registered called number. If the callee is idle, Subscriber A will hear the ring back tone. When the callee hooks off, both parties begin to talk. At this time, the registered service will be automatically cancelled. In other case, if the callee is busy,


3-24

Subscriber A will hear the busy tone, and after 2 minutes, the switch will ring Subscriber A again. If the switch fails to establish the call after five attempts, the registered service will be automatically cancelled.

If Subscriber A does not hook off when the telephone rings, the ringing tone will stop after 25 seconds. Two minutes later, the switch will ring Subscriber A again.




Subscriber A dials #67# (on DTMF phone) or 151167 (Pulsed phone)

Subscriber A hears the acknowledgement tone of successful cancellation of the service


IV. Example

Subscriber A whose number is 8883080 with the "booking call" service authority

HH = 10

MM = 20

Subscriber B whose number is 8883010




Subscriber A dials *67*1020*8883010# (on DTMF phone) or 16710208883010

Subscriber A hears the acknowledgement tone of successful registration of the service



At 10:20 after successful registration, the switch will first of all send the ringing tone to Subscriber A. When Subscriber A hooks off, the switch will automatically originate a call to Subscriber B (whose number is 8883010). If the callee is idle, Subscriber A will hear the ring back tone. When the callee hooks off, both parties begin to talk. At this time, the registered service will be automatically cancelled. In other case, if the callee is busy, Subscriber A will hear the busy tone. After 2 minutes, the switch will ring Subscriber A again. If the switch fails to establish the call after five attempts, the registered service will be automatically cancelled.

If Subscriber A does not hook off when the telephone rings, the ringing tone will stop after 25 seconds. Two minutes later, the switch will ring Subscriber A again.


3-25




Subscriber A dials #67# (on DTMF phone) or 151167 (Pulsed phone)

Subscriber A hears the acknowledgement tone of successful cancellation of the service


Note: z If the subscriber originates and successfully establishes another call before the pre-set time, the

booked call will be automatically cancelled. z The called numbers of the booking calls can be either national or international numbers.

3.12 Call Back On Busy

I. Meaning
