Circuit Card Descriptions 22. SWITCH MATRIX CARD 22.01 The Switch Matrix Card resides in a dedicated card slot directly to the right of the MCC in the control bay of the 672-portSX-200 DIGITAL PABX. It expands the DX switching matrix, the static non-volatile RAM, and the resources of the 7720 Digital Signal Proces- sor. The card measures approximately 325 mm x 366 mm (12.8” x 14.4”). Facilities 22.02 The Switch Matrix card provides: 024 x 24 link DX array 0Digital Signal Processor lDial Tone Filter 0Ringing Reference Generator a8 Kbytes Non-volatile Static RAM DX Array 22.03 The DX Array on the Switch Matrix Card consists of a 24 x 24 link switching array provided by 9 Mite1 DX chips with balanced drivers and receivers. Ringing Reference Generator 22.04 The Digital Signal Processor generates PCM data corresponding to a 20Hz sine wave, which is passed through the DX array. A codec then converts the PCM to analog. This 20 hz signal is then filtered and distributed via the backplane to the Bay PSU, which con- tains a ringing amplifier. Non-volatile Static RAM 22.05 Any time the user enables a function the changed data (extension number, type of forwarding) must be saved in a non-volatile memory so that it is not lost on power down or system failure. The Static RAM acts as a buffer for this sort of data. As the data accumulates, finally filling up the buffer, it is then transferred to disk. This reduces disk running time, increasing the disk drive’s life- span. During power-off periods, the static RAM is powered from a large capacitor, providing 72-hour holdover time. WARNING THE SWITCH MATRIX CARD MUST NOT BE INSERTED OR REMOVED WITH THE POWER ON. DAMAGE TO ONBOARD CIRCUITS MAY RE- SULT.Page 51
Circuit Card Descriptions 23. Tl DIGITAL TRUNK CARD Brief Description23.01 The Tl Trunk card interfaces a single Tl trunk circuit to the SX-200 DIGITAL PABX. The Tl protocol is used primarily in North America. Facilities23.02 The Tl Trunk Card provides the following facilities: lTl Clock - System Clock Phase Comparator lBidirectional Tl to ST-BUS@ data rate and format conversion lLine Equalization General Description23.03 The Tl interface will transmit and receive 24 8-bit voice/data channels on a 4-wire digital trunk operating at 1.544 Mb/s. The Bay Controller performs all control functions. 23.04 To provide signaling information on the Tl line, data bits are “stolen” from each channel to provide channel associated sig- naling. 23.05 The Tl Trunk Card includes a phase comparator which, through the Tl Clock Module on the Main Control Card, keeps the system clock in phase with the incoming frame rate clock. This pre- vents data losses due to clock rate differences. (Refer to the Part on TlClock Module in this Section). 23.06 The SX-200 DIGITAL system supports a maximum of two TlTrunk Cards per digital bay. In 336, 456 or 480-port systems Bay 2 supports only one Tl Trunk Card. 23.07 One incoming Tl trunk is selected as the primary timing source; the system locks its PCM clock and all other Tl trunk cards in the system to this incoming data stream. 23.08 The telephone company provides on-site Tl termination equip- ment, the Channel Service Unit (CSU). Shielded twisted pair cables are run from the CSU to the SX-200 DIGITAL backplane. The TlTrunk card includes switches to set appropriate line equalization for cable lengths up to 200 metres (655 feet) from the CSU. 23.09 The Tl Trunk card can be installed in any even-numbered, high-power (upper) digital card slot. An adapter fitted to the backplane connector provides a 15-pin D-Sub connector for the Tlfacility and a 25-pair connector to maintain access to the adjacent odd-numbered card slot. Only 1 Tl Trunk card can be installed in each digital bay. Page 53
SECTION MITL9109-094-125-NAElectrical Description 23.10 in the transmit direction, the data from the system PCM link must be converted from the Mite1 ST-BUS format of 32 chan- nels at 2.048 MBit/set to the Tl format of 24 channels at 1.544 MBit/set. To match the number of data channels, the TI card skips every fourth channel on the ST-BUS links. The Tl interface circuits retime the output data to I.544 Mbits/set and add the framing bits. 23.11In the receive direction, the framing bits are removed, the data is retimed to 2.048 MBit/set and the channels are mapped onto the system PCM link in the same manner as above, with every fourth channel left empty. 23.12 The system runs a loopback test during power-up or reset. A relay is operated to loop the card’s transmit line back to its receive line, removing the transmit data from the output line. A 6db attenuation is automatically added to the signal during loopback, to simulate actual transmission. The card remains in loopback until the test is passed. 23.13 The relative phase of the TI and system clocks is determined as follows: An 8 KHz clock output derived from the incoming frame rate is divided by two. This 4KHz signal gates a counter, which counts the number of cycles of the system 2.048 MHz clock occuringduring one cycle of the 4 KHz signal. This phase count is sampled every 100 ms. The oscillator on the Tl Clock Module on the Main’ Control Card is adjusted to keep the phase count value constant over a longer term (16 seconds). The Tl circuit data buffer accommodates short-term phase variation (jitter). Indicators 23.14 If any of the data channels on the TI link are active, the upper front panel LED lights, giving visual indication of channel activ- ity.23.15 If the SX-ZOO DIGITAL cannot phase-lock to the incoming sig- nal, the yellow (NO SYNC) LED lights. 23.16 The lower red LED is the Card Alarm. It flashes when the card is busied out or if the system diagnostics finds a malfunction on the card. Physical Description 23.17 The card measures approximately 158 X 368 mm (6.2” X 14.5”). It connects to the backplane via an 88-pin edge connector. Page 54
