Parameter

Parameter ID Parameter Name Parameter Description

NI Network indicator It is a parameter used for the MSOFTX3000 to interwork with the BSC. It specifies the signaling network that bears the A interface signaling message (BSSAP message) between the MSOFTX3000 and the BSC. The option may be International network, International reserved network, National network or National reserved network. It is set to National reserved network by default.

The BSC interworks only with the MSC on BSSAP signaling. In most countries or regions, to save the SPC resource of public network, the A interface

signaling message between the MSC and the BSC is transmitted over the national reserved network as specified by network carriers. Therefore, the default value can be directly used. For countries or regions with limited network scale, to simplify network planning, carriers may specify that the A interface signaling message is transmitted over other signaling networks (such as national network). Therefore, the parameter must be set based on carriers' requirements.

In addition, if one MSOFTX3000 is configured with multiple BSCs, keep the value of this parameter consistent on all the BSCs.

DPC DPC It is a parameter used for the MSOFTX3000 to interwork with the BSC. It indicates the destination signaling point code used when the MSOFTX3000 interworks with the BSC on A interface signaling. The value can be a decimal number, hexadecimal number or subsection format of up to 11 digits. The parameter must be defined by ADD OFC before being referenced here.

In addition, a BSC can indicate only one DPC and the BSSAP sub-system corresponding to the DPC must be preset by ADD SCCPSSN.

OPC OPC It is a parameter used for the MSOFTX3000 to interwork with the BSC. It indicates the

originating signaling point code used when the MSOFTX3000 interworks with the BSC on A interface signaling. The value can be a decimal number, hexadecimal number or subsection format of up to 11 digits.The parameter must be defined by SET OFI or ADD OFI before being referenced here.

In addition, a BSC can indicate only one OPC and the BSSAP subsystem corresponding to the OPC must be preset by ADD SCCPSSN.

BSCNM BSC name The value is a string of characters. It describes a specific BSC for identification.

The value of the parameter must consist of one or more of the following:

Digits: 0-9 Upper case letters: A-Z Lower case letters: a-z Hyphen: - Dot: .

If the parameter is not specified, the system defined a default BSC name for the record. You can change the value of BSC name by using the MOD BSC.

CAPABILITY List Of BSC Capability It is a parameter used for the MSOFTX3000 to interwork with the BSC. It indicates whether the BSC supports special services or applications. It is set to Support Direct Retry After Handover Fail by default. The meanings of the options are as follows:

Support Channel Needed IE in CC Paging : It indicates that when connecting an MT call, the MSOFTX3000 sends the Paging message carrying the channel needed information element (IE) to the BSC. That is, all mobile terminals in the BSC area adopt the specific wireless channel (TCH/F or TCH/H). The wireless channel type depends on bit 3 of P164 (paging software parameter 2). It is set to TCH/F by default.

Support Channel Needed IE in SMS Paging : It indicates that when initiating the SMS service, the MSOFTX3000 sends the Paging message carrying the channel needed IE to the BSC. That is, all mobile terminals in the BSC area adopt the fixed wireless channel (SDCCH) in the SMS service.

channel (SDCCH) in the SS service.

Support Channel Needed IE in PSI Paging : It indicates that when initiating the PSI service, the MSOFTX3000 sends the Paging message carrying the channel needed IE to the BSC. That is, all mobile terminals in the BSC area adopt the fixed wireless channel (TCH/F or TCH/H) in the PSI service. The wireless channel type depends on bit 3 of P164 (paging software parameter 2). It is set to TCH/F by default. With the PSI service, the HLR can obtain the detailed location area to which a called IN subscriber roams.

Support LCS : It indicates that the BSC supports the LCS service. When the GMLC sends the Provide Subscriber Location message to the MSOFTX3000 through the Lg interface, the MSOFTX3000 sends the Location Request message to the BSC. With the LCS service, the BSC can locate the mobile station by the specific mobile location technology.

Support Service Handover IE in ASSIGNMENT and HANDOVER : It indicates that when

connecting a call, the MSOFTX3000 enables the Assignment Request message and Handover Request message sent by the BSC to contain the Service Handover IE.

Support Private Broadcast Message : It indicates that the BSC supports processing of private (non-protocol) broadcast messages.

Support BSC Local Switch : It indicates that the BSC supports the local switchover function. The local switchover function is used to facilitate communication between two mobile subscribers under the control of the BSC by utilizing TDM switchover resources inside the BSC. The local switchover function can be performed by the BSC individually without requiring extra work of the MSC.

Support Reassignment After Direct Retry Handover Fail : It indicates that the BSC supports the reassignment function after direct retry handover fail.

SUPPORT_PRIVATE Channel Need Extend : Before the option is selected, at least one of the options Support Channel Needed IE in CC

Paging , Support Channel Needed IE in SMS Paging , Support Channel Needed IE in SS Paging , and Support Channel Needed IE in PSI Paging must be selected. After the option is selected, you can add the information on the service type and the paging times to the Channel Needed information element of the Paging message.

Support HSCSD : It indicates that the BSC supports the HSCSD function. HSCSD is short for high speed circuit switched data.The option Support HSCSD is determined by the function option of the license and the bit 13 of P1002, that is, the configuration of Support HSCSD takes effect only when the license supports the HSCSD and the bit 13 of P1002 is opened.

Support IMSI Based handover : It indicates that the BSC supports the IMSI-based handover function. When a mobile subscriber connects to the access network or performs a handover, the MSC provides the IMSI information for the BSC.

BSCSTAT BSC status It is used to set the status of the BSC in the configuration database. It indicates whether the system adopts the BSC. It is set to Available by default.

DTXP Discontinuous transmission flag

It is a parameter used for the MSOFTX3000 to interwork with the BSC. It indicates the transmission mode when the BSC transmits the voice. The

meanings of the options are as follows:

Common : It indicates that the MSOFTX3000 transmits the voice stream in continuous transmission mode. The BSC adopts continuous 13-kbit/s links to encode and transmit the voice stream, irrespective of whether a subscriber is speaking (voice activation).

Discontinuous : It indicates that the MSOFTX3000 transmits the voice stream in discontinuous transmission (DTX) mode. Thus, when a subscriber is speaking (voice activation), the BSC adopts 13-kbit/s links to encode and transmit the voice stream; when no subscriber is speaking (voice inactivation), the BSC adopts 500 bit/s links (only for comfortable noise transmission). The DTX mode aims to decrease the interference level of the voice transmission over the air and improve the efficiency. In addition, it can save the power loss of the mobile terminals.

MLAIF Location area not unique flag

It indicates whether multiple location areas are planned in the BSC. It is set to Unique by

default. The meanings of the options are as follows:

Unique : Only one location area is planned in the BSC. In this case, LAI number must be set in this command and then the parameter can be set by ADD LAIGCI.

Not unique : Multiple location areas are planned in the BSC. In this case, LAI number can be set only by ADD LAIGCI.

LAI LAI number It is a parameter used for the MSOFTX3000 to interwork with the BSC. It indicates the LAI number in the BSC network. It is valid only when Location area not unique flag is set to Unique. An LAI number can have up to 10 characters in length, with the encoding format as MCC + MNC + LAC, such as 460-00-4777. The principles for setting the parameter are as follows:

When the MNC has two characters, set LAI number to 9 characters.

When the MNC has three characters, set LAI number to 10 characters.

The location area code (LAC) in LAI number cannot be 0x0000 or 0xFFFE.

MSAREANAME Multi-area name It indicates the local network name of the multi-area network. The value is a character string. The value is 1 to 32 characters. The parameter must be defined

by ADD MASI before being referenced here.

When you enter a string through the LMT, the system converts all lower-case letters into upper-case letters, and then deletes the spaces at the extreme left and extreme right of the string. For example, the string " Area abc " entered through the LMT is converted into "AREA ABC" before it is further processed in the BAM database.

DMNAME Domain name It specifies the domain of the current data record. The value is a string of up to 32 characters. The principles for setting the parameter are as follows:

If you do not specify Domain name, the domain of the user account you use to log in to the BAM is used by default.

If you use a public domain account to log in to the BAM, you can specify that the current data record belongs to the public domain or a private domain.

If you use a private domain account to log in to the BAM, the current data record must belong to the private domain.

The public domain, always named PUBLIC, has been configured in the BAM database. You cannot remove or modify the public domain. The private domains are

configured on the M2000. The name of a private domain cannot be PUBLIC. To query existing domain names, run LST DOMAIN on the LMT.

Domain name provides role-based and domain-based management. A domain, as a collection of resources, is an attribute of your user account. A resource can be regarded as a key field of a data record. A domain determines the resources over which you have full control authority. Domains are categorized into two types: public domain and private domain. If your user account belongs to the public domain, you have in theory full authority to control all resources, including public-domain and private-domain resources. The authority to operate the resources, however, is determined by the authority of the command group that is accessible to your user account. If your user account belongs to a private domain, you have full control authority over the resources of the private domain, but read-only authority over the resources of the public domain or other private domains. That is, you can run only the LST and DSP commands on these resources. The administrator account belongs to the public domain by default and cannot be set to any private domain.

This command is used to set the GSM bearer capability of the A-interface circuit, for instance, whether the A-interface circuit can support:

Voice services Data services Full rate Half rate

This table supports role-based and domain-based management. It is a resource of a private domain.

You can configure several A-interface circuit pools of different GSM bearer capabilities. You can specify the circuit pool for an A-interface trunk group when adding the A-interface trunk group by using ADD AIETG. Therefore, you can set different GSM bearer capabilities for A-interface trunk circuits in different office directions.

Parameter

Parameter ID

Parameter Name

Parameter Description

CPNAME Circuit pool name

It defines the name for a circuit pool in the configuration database. The name is defined globally.

Value range: a string of up to 32 characters

The rules for setting the parameter are as follows:

When you enter a string through the LMT, the system converts all lower-case letters into upper-case letters and deletes the spaces on the extreme left and extreme right (if any) before performing further operations on the BAM

database. For example, when you enter " Area abc ", the system converts it into "AREA ABC".

To change the value of Circuit pool name from A to B in a data record that has been configured by using this command, run MOD ACPOOL with New circuit pool name set to B. After you run MOD ACPOOL, Circuit pool name is changed from A to B for all data records that originally reference Circuit pool name A.

BCR GSM bearer capability

It defines the GSM service types, for example, voice service and data service, that the circuit pool can bear.

Values:

Full rate speech version 1: The GSM full rate (FR) coding/decoding algorithms are used for voice services. The voice service bandwidth is fixed to 13 kbit/s.

Full rate speech version 2: The GSM enhanced full rate speech codec (EFR) coding/decoding algorithms are used for voice services. The service bandwidth is fixed to 12.2 kbit/s.

Full rate speech version 3: The FR adaptive multi-rate (AMR) coding/decoding algorithms are used for voice services. The service bandwidth can be 4.75 kbit/s, 5.15 kbit/s, 5.90 kbit/s, 6.70 kbit/s, 7.40 kbit/s, 7.95 kbit/s, 10.2 kbit/s or 12.2 kbit/s.

Half rate data : Data services are transmitted at half rate. The service bandwidth can be 4.8 kbit/s or 2.4 kbit/s.

The default service types that the circuit pool supports are Full rate speech version 1 and Full rate data.

DNA Domain name It specifies the domain of the current data record.

Value range: a string of up to 32 characters

The rules for setting the parameter are as follows:

If you do not specify Domain name, the domain of the user account you use to log in to the BAM is used by default.

If you use a public domain account to log in to the BAM, the current data record can belong to the public domain or a private domain.

If you use a private domain account to log in to the BAM, the current data record must belong to the private domain.

The public domain, always named PUBLIC, has been configured in the BAM database. You cannot remove or modify the public domain. The private domains are configured on the M2000. The name of a private domain cannot be PUBLIC. To query existing domain names, run LST DOMAIN.

Domain name provides role-based and domain-based management. A domain, as a collection of resources, is an attribute of your user account. A resource can be regarded as a key field of a data record. The domain determines the resources on which you have full control authority. Domains are categorized into two types: public domain and private domain. If your user account belongs to the public domain, you have in theory full authority to control all resources, including public-domain and private-domain resources. The authority to operate the resources, however, is determined by the authority of the command group that is accessible to your user account. If your user account belongs to a private domain, you have full authority on the resources of the private domain, but read-only authority on the resources of the public domain or other private domains. That is, you can run only the LST and DSP commands on these resources. A super administrator account is only a public domain account by default and cannot be changed to a private domain account.
