    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

    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.

    							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.
