2. Introduction

2.1. General Characteristics

FOX505 is a compact Access Mux with transport capacity up to STM-1. The network element fully supports ring and linear topologies and is ideal to feed higher order SDH-backbones. Its extended operational temperature range and a wide choice of interfaces match the requirements of most utilities.

The 19 wide / 4+21 units high chassis provides 14 front-access slots for: x 2 redundant CPUX modules x 2 redundant, hot swappable power supply modules x 2 high speed modules (e.g. STM-1) x 8 slots for any combination of other interface cards (e.g. E1, voice, LAN, legacy, G.HSDL etc.)

The controller boards (CPUX) provide management access (Ethernet & RS232) as well as external alarm inputs (3) and one output. In addition, an external synchronization input is available. Two different board hardware versions with different cross-connect sizes allow optimizing this rugged network element technically as well as cost-wise.

The design of the multiplexer allows contiguous operation at temperatures up to 55oC.

Whatever supply voltage in the range of 93-250 VAC / 36-72 VDC is applied, it can be handled by the same type of power supply module and redundant load-sharing operation is fully supported.

The device complies with the typical Ethernet / LAN utility requirements in the field of access-services. An Ethernet switch board offers L1 & L2 functionality whereas the IP / PPP board handles all TDM traffic carrying PPP-encapsulated IP-traffic.

INTRODUCTION


2.2. Common Applications

SDH network access: 64kbit/s timeslot level cross-connect for STM-1 interface receive data.

Cross-connect in any port (Grooming): it is possible to multiplex the traffic from different sub-used channels into one aggregate channel. The E1, FO, DSL, BASE BAND MODEM, V.35, G.703 64kbit/s ports data and FXO/FXO4/FXS/FXS4/FXS10/E&M voice cards can be mapped to any timeslot of any port. In this manner, any port can function as aggregate, so it can be optimized for each application. The CPUX64 and CPUX128 allow concentrating the tributaries in 2Mbit/s channels mapped into the STM-1 aggregate.

CAS cross-connect for voice channels is possible, when the interfaces configured in structured mode.

3.1. Environmental Conditions

Operation Temperature: from -5C to 55C

Storage Temperature: -40 85 C.

Relative Humidity: up to 95%, non-condensing.

3.2. Power Supply PSU

Power is supplied to the equipment via a power cable terminated with three pins connector. This cable can be connected to any type of AC outlet, within the specified voltage limits. If using DC power, the AC plug must be cut from the power cord. Use the wire corresponding to the central pin as the protection ground and the other two for DC power, regardless of polarity. The equipment chassis is connected to the protection ground.

The equipment can be powered with voltage within the range specified in Table 1 below. The voltage selection is automatically done by the equipment, for both the main supply and the optional back-up power supply. Two supplies can be installed, for redundant operation. The power supply modules allow live insertion, so you do not need to switch the power off, if you need to plug in or remove the power supply module.

BOARD Power consumption

The power input Boards supportedDC AC

Table 3. Power consumption

* When total power is over 160W, while operating in DC, the input voltage must be higher then 40V.

The quantity and type of cards installed must be taken in consideration during power consumption

calculation. The values provided in the Table 3 above.

3.3. Consumption Calculation

This topic explains how to calculate the total power consumption of equipment. This information can be used for calculation of power supplying and cooling systems. x Check the energy supply font model x Choose a column. Use only one column, referring to operation conditions

o If energy supply font is in DC, use only DC W column o If energy supply source is in AC, use W column for cooling dimensioning only. All other

conditions must use VA column x Sum every cards energy consumption

If equipment is supplied from DC and AC sources, calculate the total power consumption considering the highest power consumption situation.



Example of consumption calculation: if total power is 60W while using DC-W and 93VA when using AC-VA, it must be considered 93VA as total power.

Example of cooling calculation: if total power is 60W in DC-W and 53W in AC-W (for each energy supply source), take the highest value into consideration.

Table 9. Ethernet connector RJ45

The front panel connectors have the following use:

x RS232 Connector: it connects the MUX serial communication cable between the equipment and the user terminal (see Table 7).

x ALARM Connector: it has the alarm input and output connections (see Table 8).

x RJ45 Connector: connection to Ethernet 10/100BaseT. It can be directly connected to a hub or switch (see Table 9).

x BNC Connector: to connect a 2048kHz external clock source.

The user must make sure there is no voltage difference between the Mux DB9 pin 5 (signal ground) and pin 5 of the DB9 (or DB25 pin 7) for the PC or terminal. If this happens it will damage the Mux and the PC or terminal serial interfaces. To check that there is no voltage difference, use an AC voltmeter to check the voltage between these pins. If there is a voltage difference, check if the MUX and the PC are properly grounded and connect the signal ground to the MUX protective ground. This should solve the problem. If the above conditions are met, then the serial cable can be connected without turning off the equipment.



3.7.1. LED indicators

There are 6 LEDs in the CPUX front panel. Their function is described as follows (even if the CPUX is in active or standby mode).

Power LED indicates that FOX505 is turned on.

If the CPUX is in standby mode, the ALARM LED indicates that the card cannot take control and have lost its synchronism with the main CPUX. The main CPUX ALARM LED shows 3 different critical alarms (Critical, High or Low). If the LED is on (red light) it means Critical alarm. If it blinks twice and fast, it means High and if it blinks in intervals longer than 1 second it means Low alarm.

When the CPUX is active, the FAIL LED will turn on whenever there is a hardware fail happening. Otherwise, it will be kept off.

The TEST LED indicates that there is a test going on. It will be kept on while any test is being executed in any interface.

When the CPUX is active, the LED ETH_LINK turned on will indicate that the front panel Ethernet Link (10/100Base-T) is active. Otherwise, the LED will turn off in normal conditions.

THE CPUX_ACTIVE LED indicates if the CPUX is on (LED on) or is in standby (LED off) mode.

GENERAL OPERATION


4. General Operation

The main characteristic of the FOX505 is its capability of directly cross connecting data from a PDH network, incoming from its tributaries, to data incoming from an SDH network (HS interfaces).

The CPUX cross-connection matrix links the PDH tributaries and the HS interfaces.

4.1. Cross-Connection Matrix

In CPUX64 the matrix is composed of 61 data lines and three lines dedicated to management channels, each one with 2Mbit/s rate carrying 32 timeslots of 64kbit/s.

In CPUX128 the matrix is composed of 257 data lines and three lines dedicated to management channels, each one with 2Mbit/s rate carrying 32 timeslots of 64kbit/s.

Each timeslot of a matrix line can be mapped to any timeslot of any other line, performing also the CAS cross-connect whenever applicable.

The connection of a tributary interface to the matrix occurs independently of user action, however, for the HS interfaces, the connection will be performed when the user maps data from a VC12 to the connection E1 interface.

When considering HS interfaces, the matrix connection will be established whenever the user maps the VC12 Data to the E1 connection interface.

Each of the equipment cards transferring data will use at least one line in that matrix. See Table 10 for further details. The matrix use should always be taken into account when designing a network with the FOX505, for the matrix has limited capacity.

An example of matrix use is now presented, showing the use of Table 11.

Table 11. Example of Matrix Seizure

(*) According to evaluation of use described below.

Considering that data will be mapped for VC12 and then transferred to the other SDH network equipments, data will be distributed in the following way (for example):

x E1_1 (KLM111): data from slot H (2*512kbit/s), from slot E (6*128kbit/s) and from slot C (64kbit/s);

x E1_2(KLM112)/E1_3(KLM131): data from both slot F interfaces (2048kbit/s);

x E1_4(KLM211): data from slot B, port 1 (1024kbit/s), data from slot A (640kbit/s);

x E1_5(KLM322)/E1_6(KLM371)/E1_7(KLM373): each one of the three remaining slot B ports (1024kbit/s) and two slot D ports (2*256kbit/s).

From this evaluation it is possible to conclude that 7 matrix lines will be needed to place data incoming from the PDH network.

In this example 20 matrix lines were needed. There would still be lines available for timeslot cross connecting (64kbit/s) STM1 ring VCs or for future network expansion.

GENERAL OPERATION


4.2. System Clock

As data incoming from each of the equipment interfaces will be cross-connected in a single commuting matrix, it is essential for correct operation that the system is employing a single clock source.

The user can define up to six clock hierarchies for the equipment, corresponding to the interfaces that are capable of providing clock. There are two switching methods that the equipment can employ: hierarchy switching and sync messages switching.

For both methods the non-reversible mode can be used, avoiding an intermittent clock reference from affecting the system. Alternatively, the user can use the reversible mode, allowing the system to switch to its best configured clock source that can provide system clock at that moment.

4.2.1. Hierarchy Switching

This method is based in the user-defined clock source priorities to choose which one the equipment will use.

The six hierarchies each have a priority, where the lowest numbered hierarchy is the highest priority, being used whenever possible.

The operation of this method is simpler, but it does not guarantee that the best available reference is being employed.

4.2.2. Sync message switching

The clock switching by sync status message is based upon the existence of a quality indicator for each clock hierarchy. This indicator can be automatically updated for STM-1 links or manually inserted for the other cases.

The quality indicators are used to evaluate the quality of the clock received at each hierarchy and, based on that quality, provide information so the equipment can choose the best clock available.

Within the STM-1 network, the clock quality indicators travel in the S1 byte of the multiplexing section and are changed by the equipments as failures are detected in sync sources or switching in the network occur.

The user can then individually configure, for each clock hierarchy, the quality of the input to be considered, and also the output quality to be sent to the STM-1 links (in the S1 byte) when each of these sources is being used. The output quality, however, cannot be greater than the input quality.

When the input quality is configured for the automatic mode, the quality of the reference will be obtained from the message received in S1. When the output quality is configured for the automatic mode, the equipment will copy the input quality value to the clock output quality.

Using automatic input clock quality has application only for sync sources that have a valid quality indicator, that is, only for the sync sources derived from the STM-1 lines.

GENERAL OPERATION


4.3. Hot Restart

One of the important equipment characteristics is its ability to do firmware updates with a minimum down time.

The process comprises storing the main equipment information before it is being reset and using this data later on, thus avoiding unnecessary reprogramming and reconfiguring of the cards already inserted in the equipment.

Whenever a firmware upgrade is performed, the unsaved configurations will be saved to ensure that the equipment will restart with the configuration that was active before the upgrade.

Whenever there is an equipment restart, the protected links will try to follow the path configured as the work path, leading to data loss of around 50ms in these links, if they are operating within the protection section.

The equipment will try to use the best available sync source. The blocked reference status is not kept when the equipment is restarted. Data losses of up to one second can occur when the equipment operates with regenerated clock.

CPUX REDUNDANCY


5. CPUX Redundancy

To minimize equipment unavailable time caused by hardware failures and possible equipment firmware problems, the FOX505 allows using two CPUX cards operating in redundant mode.

In this way, the strategic client services will be safe against problems in the CPUX card, so that a defective card will cause only some seconds of down time, even if the defective card takes days to be replaced.

5.1. Operating Characteristics

5.1.1. Redundant Operating Mode

It is up to the user to configure if the equipment will operate with CPUX redundancy or not. If this option is enabled, there must always be two CPUX cards inserted in the equipment. Otherwise, the redundancy failure alarm will occur. While this alarm is active, the equipment will not accept firmware updates.

Once redundancy is enabled, there are two possible roles for each of the equipment CPUXs:

x Active: all data pass through the active CPUX. This is the only CPUX directly accessible to management, and only if it fails or if there is user intervention it will leave this state.

x Standby: the role of the standby CPUX is to reestablish data flow after a failure or if the active CPUX issues a request.

Choosing the role to assign to each CPUX occurs during system initialization. This is not configurable and it does not depend on the slot in which the card is inserted.

Note that whenever the standby CPUX becomes active, data errors will appear in the interfaces in use, for the switching matrix is stored in the CPUX. The unavailable time depends upon the reason for the card switching and goes from 3 seconds to 4 minutes.

To ensure that the standby CPUX can be in charge of the equipment data, the active CPUX starts the system sync process whenever it detects the standby CPUX. This sync process occurs whenever the configuration or the equipment firmware is changed.

It is only possible redundancy between equal models of CPUX. Two CPUX128, for example. In case that a CPUX64 is installed together with a CPUX128, it will not have CPUX redundancy.

CPUX REDUNDANCY


5.1.2. Sync process

The sync process is the process by which the active CPUX tries to update the information of its database in the standby CPUX. In the sync process, other than the equipment configuration data and some status information, the standby CPUX firmware is also updated.

From the moment that the standby CPUX has its database in sync, it will be prepared to take control of the equipment and will do so if necessary. If any sync problem arises, the standby CPUX sync failure alarm will become active and user action will be requested to restart the process. If sync problems occur, it is usually a hardware failure.

5.1.3. Switching Test

The user can switch from the active CPUX to the standby CPUX, in this way being able to servicing in an active CPUX.

When this procedure is performed, there will be data loss, even if the standby CPUX is in sync. In this case the errors will last few seconds only. If the standby CPUX is not ready, the user should not switch, for it could lead to permanent failure in the client data links.

ELECTRICAL E1 CARD - E1


6. Electrical E1 Card - E1

The FOX505-E1 card has one E1 interface, with impedance selectable (75ohms or 120ohms in the same model (BNC connector for 75ohms impedance and RJ48 Connector for 120ohms impedance).

Frame structure (transparent or structured) as defined by ITU-TS Recommendation G.704. The number of timeslots available for the user, in the framed mode, is at most 31, for timeslot 0 is used for frame sync. For telephony applications using Channel Associated Signaling (CAS), there are only 30 timeslots available, for timeslot 16 transports CAS signaling.

Speed of 2048kbit/s, using HDB3 coding, as defined by Recommendation G.703.

It allows management of remote equipments.

6.1. Electrical E1 Interface and its Indicators

There is a sync LED on the Electrical E1 interface card panel. When operating in structured mode, the LED indicates carrier present and also presence of the Frame Alignment Signal. When operating in Transparent mode (32 data channels), the LED only indicates carrier present.

6.2. Backup Line

It is possible to configure the Electrical E1 card to be a backup of another card. The Backup line is available for some of the interfaces (Electrical E1, Optical E1 and E1-Quad cards), however, the others are not capable of having a backup link.

A backup link can be configured in one of the following operation modes: off, automatic, semi-automatic.



a. Off: means that the equipment will not switch to the backup interface when there is a failure in the main link. This option is generally used to force the main link operation, even if it is not operating adequately.

b. Automatic: switches data to the backup link. Data flows back through the main link only after this link remains stable and operating for around two minutes, or if the backup link goes down when the main link is on.

c. Semi-automatic: makes that after a failure data continue flowing through the backup link unless the backup link fails.

6.3. Configuration straps

This card possesses 3 straps of configuration, responsible for configuring the E1 interface physically.

8. Electrical E1 Card - E1-16


The FOX505-E1-16 card has 16 independent E1 interfaces. There are two models, one with an impedance of 75ohms and the other with an impedance of 120ohms. The connector used for both models is the Telco64.

Frame structure (transparent or structured) as defined by ITU-TS recommendation G.704. The number of time slots available for the user, when on the framed mode, is maximum 31, because time slot 0 is used for the frame synchronization. On telephony applications with CAS, only 30 time slots are available, as time slot 16 conveys the CAS signaling.

Speed at 2048kbit/s on each interface, using the HDB3 encoding, as defined by recommendation G.703.

Allow the remote equipment to be managed.

The E1-16 interface may use a backup link (as shown in item 6.2).

OPTICAL E1 CARD FO/FO2


9. Optical E1 Card FO/FO2


For historical reasons, the card supports an old Frame20 mode. Its however recommended to use the standard single E1 mode.

On the Single E1 configuration the cards follow the ITU-TS recommendation G.704. In this instance, it is possible to choose one of the 4 connection E1s with the matrix in order to be directly connected to the optical interface.

The Optical E1 interface module may be regarded as an Electrical E1 module. The essential difference is the connection means, therefore, there is no line impedance configuration such as on the Electrical E1 interface.

The FO card is provided in two models, differentiating from one another by the quantity of interfaces available. One model presents one optical interface (FO) and the other two (FO2).

A synchronization status indication LED is made available for each optical interface. This status is indicated both on the Frame 20M mode and Single E1 mode.

The FO card front panel is illustrated in Figure 24. And the FO2 card panel is illustrated in Figure 25.

Figure 24. FO Front Panel

Figure 25. FO2 Front Panel

Transmitter: Laser Diode of 1310nm or 1550nm, with power options between 0 and -15dBm.

Receiver: Use a PIN photodiode. Minimum level of -34dBm for BER of 10-9 on single mode.

On very short links, where the power present on the receiver is higher than those specified above, it may be necessary to use an attenuator to reduce it and avoid the saturation of the input amplifier.

The range may vary in view of the link quality. The equipment leaves the plant with at least the specified power. It is common place that the power is several dB above the minimum power (e.g. -10 dBm on a short range card).

The transmitter has a circuit which offsets variations of the laser characteristics in view of the temperature and ageing.



The optical signal encoding is proprietary, ensuring that BER (Bit Error Rate) levels are kept regardless of the data sent.

The laser transmission power can also be selected, characterizing the card as short or long range.

The optical cards are always supplied with SC-PC connectors, including in case of cards for use with bidirectional fiber single fiber.

The FO2 card optical interface may use a backup link (as shown is item 9.3).

9.2. Optical modules available

Table 17. Characteristics of the Interfaces Optics

* The estimated range already allows for a 3dB loss caused by connections, splices and other optical phenomena.

1) Considering Multimode Fiber with loss of 2dBkm (1310nm).

2) Considering Multimode Fiber with loss of 0,36dBkm (1310nm).

3) Considering Multimode Fiber with loss of 0,25dBkm (1550nm).



9.3. Backup line

It is possible to configure the FO2 card in order to use one of the interfaces as a backup link of the other interface.

The backup may be configured in one of the following operating modes: OFF, automatic or semiautomatic.

x OFF: Means that the equipment will not divert to the backup mode when a fault occurs on the main link. In general this option is used in order to force the operation of the main link, even if this is not operating properly.

x Automatic: Causes the data to be switched over to the backup link and only return to the main link after keeping stable and operating for (approximately) 2 minutes or when the backup link drops (in case the main link is operating).

x Semiautomatic: Causes the data to not travel again through the main link unless the backup link fails.

It is also possible to use a backup link for the E1 for connection with the matrix (as shown in item 6.2).

9.4. Tests on the FO/FO2 Interface

9.4.2. Local Digital Loop Test on the Physical Interfaces - LDL


Figure 27. LDL test diagram on the physical interfaces at the FO/FO2



9.4.3. Laser Tests

The FO/FO2 cards implement the ALS protocol to prevent the laser from being ON when there is no fiber connected. The user may change the ALS behavior through the following tests:

x LASER OFF: Forces the laser shutoff.

x LASER ON: Forces the laser to remain ON, regardless of existing fibers connected on the card.

9.4.4. FO HW3 Card Tests

The FO HW3 card makes it possible for the front BERT and back BERT tests. This test is not possible on the FO/FO2 cards.

The optical interface module uses transmitters with non visible laser radiation. Never look directly at the laser terminals or the optical fiber. Exposure to laser emission may cause partial or total loss of vision.

G.SHDSL - DSL2 CARD


10. G.shdsl - DSL2 Card

The G.shdsl interface card supports two lines.

The connections take place via a RJ45 with pinning as per Table 18.

Signal RJ45TIP 4

RING 5

Table 18. Pinning for the G.shdsl interface RJ45 connector

The G.shdsl (G.991.2) pattern specifies 2-wire symmetric connection for subscriber lines.

The equipment G.shdsl ports can transport from 1 to 32 timeslots with channel alignment.

Figure 28. G.shdsl card panel - FOX505-DSL2

Each port may reach 2048kbit/s on an independent way.

The TC-PAM coding assures spectral compatibility with other service types, like ADSL and ISDN. The achieved range is 15 to 20% greater than for modems that use 2B1Q coding in the same speed. It gets rates 35 to 45% greater for the same distance.

The power of the signal sent is 13,5dBm for rates lower than 2048kbit/s and 14,5dBm for 2048kbit/s.

The G.shdsl interface allows information on CAS (Channel Associated Signaling) to be sent, when there is band available, that is, when at least one 64k time slot is idle.

The DLS interfaces may constitute one backup link (as indicated in item 6.2).

G.SHDSL - DSL2 CARD


10.1. Connection

The connection takes place through 3 basic stages:

10.1.1. Pre-Activation (Handshake)

The pre-activation stage follows ITU-T Recommendation G.994.1, which describes the handshake for xDSL transceivers.

During this stage, the two equipments change data and negotiate the parameters that will be used for the connection.

The ends implement a 12kHz DPSK modem for the NTU and a 20kHz one for the LTU to perform the handshake. The standard predefined messages are exchanged and define the common operation mode.

In this phase the final transmission rate is determined, as the Annex to be used (A or B). The type of information that will be transported (TPS-TC), the transmission frame (plesiochronous or synchronous) and many other parameters are also set.

If the interfaces do not agree on a common configuration, the two equipments abort transmission and do not go to the next stage, they try again after some time.

For the FOX505 DSL2 card, the implementation was performed so that the subscriber equipment (NTU) will always accept the configuration sent to it by the office equipment (LTU), easing their installation process.

In the handshake, the interface LED remains off, blinking once a second.

10.1.2. Activation (Training)

In this phase the two modems test the transmission line using the rate that was agreed upon during the handshake phase to determine what coefficients should be used for its receive and transmit digital filters.

During the training, the equipments use the normal line coding (TC-PAM) and do not use DPSK anymore.

First, both modems test the line. Then they exchange the pre coder coefficients that will be used during data transmission.

Two things can occur at the end of this stage: the modems go through the training phase and determine the adequate coefficients for the line, entering the data mode, or the modems could not determine the coefficients for some reason (the line is too long, too much noise, during training there was a very strong perturbation that precluded convergence, etc.) and so they abort transmission.

In the activation phase, the interface LED remains on for half a second and off for half a second.

G.SHDSL - DSL2 CARD


10.1.3. Data Mode

This is the final stage, where the modem transmits the data normally. It will use the final G.shdsl frame exchanging information as negotiated during the handshake and using the coefficients that were determined after the transmission line evaluation, during the training period.

When the interface is in sync, the status LED will remain on.

10.2. Operation Modes

10.2.1. Terminal Type

Indicates if an interface operates as LTU (office) or NTU (subscriber).

When the modem is configured as LTU, it will determine during the handshake all the connection parameters, as which Annex to be used, number of channels, clock scheme (synchronous or plesiochronous), etc. It is not possible to recover clock from the interface when configured in this mode.

When the modem is configured as NTU, the Annex configurations and clock scheme (Frame Mode) are mandatorily automatic, for it must accept any configuration set by the LTU.

It is not possible to interconnect two equipments configured for the same type of terminal, for the handshake only occurs between LTU and NTU.

10.2.2. Frame Mode

This option sets if the interface will operate in synchronous, plesiochronous or automatic mode.

When in plesiochronous mode, the transmission and reception clocks are independent from the line clock, which is generated by the LTU. The line clock precision is r 32ppm, as set by G.991.2. Periodically 4 stuff bits are automatically inserted to adequate the data clock to the line clock. This procedure is essential for the equipments to remain in sync.

When configured in synchronous mode, the line clock is the same as the data clock. The precision of the data clock is, then, the clock precision chosen as the equipment sync source. Recommendation G.991.2 specifies that the clock precision should be r 32ppm, independently of the selected clock scheme, so it is up to the user to configure a clock with such a precision to operate according to the standard (or to use a clock of lesser precision operating outside the standard bounds). In this mode the stuff bits stb1 and stb2 are always present, while stb3 and stb4 are not transmitted.

In the automatic selection mode, the LTU will use the mode selected by the NTU. If the NTU accepts any mode (automatic configuring), the synchronous mode will be used.

G.SHDSL - DSL2 CARD


10.2.3. Annex

The Annexes specify small deviations of the standard to best adequate the equipment to the used line.

Three annex options can be chosen: A, B or automatic selection.

Annex A determines the regional specifications regarding the lines operating under the conditions typically found in U.S.A. networks.

Annex B determines the regional specifications regarding the lines operating under conditions typically found in European networks.

In the automatic selection mode, the LTU will use the Annex selected by the NTU. If the NTU accepts any Annex, Annex B will be used.

10.3. Performance

The interface performance is directly related to the transmission line characteristics.

The gauge and length of the wire, the noise and the susceptibility to micro-interruptions to which the line is submitted determine which is the greatest available transmission rate.

The range also diminishes if the line presents a great number of splices and bifurcations. The length of the bifurcations also alter the line characteristics, for they can increase signal reflections and cause noise.

In a 0,4mm noiseless line, the maximum distance can be 3600 meters when working with rates of 2048Kbit/s. With the modem configured with 192Kbit/s it is possible to reach 6.300 meters.

Table 19 displays expected ranges for some rates in noiseless artificial line, having the protective ground connected to the equipment signal ground.

Data Rate(kbits/s)

Range for 2 wires 0,4mm (m)

Range for 4 wires 0,4mm (m)

192 6.300 6.300256 5.900 6.300384 5.400 6.300512 5.100 5.900768 4.700 5.4001024 4.400 5.1001536 4.000 4.7002048 3.600 4.400

Table 19. G.shdsl card range

A way of increasing the interface range is by improving the equipment shield to lessen the noise to which the receiver is submitted. For the DSL2 card, it is advisable to connect the equipment protective ground to the signal ground, otherwise the interface range will be lower.

G.SHDSL - DSL2 CARD


10.4. Electrical Protection

When the G.shdsl cards analogue lines pass through media that can suffer influence of electrical or atmospheric discharges, it is recommended to add primary protection devices to it.

10.5. DSL Interface Tests

10.5.1. Loopback Digital Local Test LDL

This loopback is used to test the external link and the two data paths. Figure 29 shows this test.

Figure 29. DSL Interface LDL Test Diagram

10.5.2. BERT Test

This test allows a quick check of the transmission quality, without using external test equipment. Figure 30 depicts this test.

Figure 30. DSL BERT Test Diagram

It is not convenient to use varistors as G.shdsl lines protection devices, for they introduce a high capacitance that can significantly reduce the interface performance. The same care should be taken with inductive type protections.

VOICE CARDS


11. Voice Cards

There are three (3) voice card options: FXO (central), FXS (user) and E&M (Tie-line). E&M is equipped with four (4) RJ-45 ports. FXO and FXS are available in different models: FXS4/FXO4 with four (4) RJ-11 ports and with telco50 connectors; FXS10/FXO10 with ten ports (Telco50).

The interfaces have user-configurable nominal impedance, selectable as 600 or 900ohms.

The voice channel frequency is from 300Hz to 3400Hz, uncompressed.

They have on-hook transmission capability, allowing data to flow through the link even when the telephone is on hook.

The channel signaling transfer is done through CAS (channel associated signaling) according to G.704. The equipment can be directly connected to a PABX, or it can be directly multiplexed in an E1 link along with other voice cards or E1 trunks.

Signal is coded using A-Law, according to G.711. The cards are also compatible with the G.712, G.713, G.714, G.715 recommendation.

There are three CAS configuration options:

Invert CAS bits A and B: in this case the information that usually goes through bit A is transmitted by bit B, and vice-versa;

Invert bit A: in this case bit A is inverted;

Invert bit B: in this case bit B is inverted.

The E&M interface accepts only dual-tone multi frequency tones (DTMF).

11.2.1. FOX505-E&M

The FOX505-E&M card is a Tie Line Equipment that communicates to the E&M interface of an central office or PABX through an interface of up to 8 wires. The PABX provides the M signal and receives the E signal. Similarly, the E&M card generates the E signal, and receives the M signal.

It can be configured for E&M signaling types I, II, IV or V, for pulse or continuous modes. Each card interface can transmit voice over 2 or 4 wires and it can be individually configured (through management software).

Figure 37. FOX505-E&M Voice Card Panel

It has one LED per interface for call status indication.

The nominal voltage used is 48VDC, and the signals are generated by applying the ground potential against this voltage, so as to generate a current increase that is felt in the remote equipment, indicating the presence of the E&M signal.

11.2.2. Signaling types

The FOX505-E&M card supports four signaling types: I, II, IV and V. The signaling type can be individually chosen by port, using straps and management software.

x Type I: For interface E&M type I, the E&M card generates the E signal for the PABX by grounding the E pin, such that the PABX detects the E signal variation due to the current increase in this wire. Similarly, the PABX generates the M signal applying a current through this wire. The E&M card detects the M signal due to the increase in current in the M wire. This requires common ground, which is provided by the SG wire.

x Type II: In the type II interface each signal has its own return and, so, it does not require a common ground. To generate the E signal, the E&M card closes the circuit, allowing the PABX current to pass through, returning through the SG wire to the PABX ground. To generate the M signal, the PABX closes the M wire circuit, allowing current to pass through this wire, which returns through SB to the E&M card detection circuit.

x Type IV: The interface type IV is symmetric and does not require common ground. The connection is established in the same way as for signaling type II.

x Type V: The interface type V is also symmetric, being a simplification of type IV. In this configuring the signals do not have a return path, so the common ground potential is needed, being provided by the SG wire.

The E&M interface accepts only dual-tone multi frequency tones (DTMF).
