Peripheral Interface Card Installation
Table 2-11
lists the peripheral interface card types that may be inserted into each card
slot in the Coral IPx 500 system. The discontinued XXXsl and XXX-200 cards are for
use in slots 1 through 3 of the main cage only. For more details, see
page 10-7,
Peripheral Card Description
.
Peripheral Interface cards listed in
Table 2-11
may require changes to
jumpers on the card that determines the electrical characteristic or
operation of each interface circuit. Refer to specific card descriptions
in “ Coral Service and Peripheral Cards Installation Manual ”, for
details.
1. Determine the position of peripheral interface cards that will be inserted into card
slots 1 through 8 in the main cage and 1 through 10 in the expansion cage.
Observe any order previously directed by a system designer or any established
convention of the distributor. The card placement diagrams,
Figure 2-36
through
Figure 2-38
, may be used as a worksheet by the system designer to establish card
placement prior to installation. Refer to
Table 2-11
to determine peripheral
interface card types.

See
page 6-55, Suggestions for Peripheral Card Distribution
for timeslot/PCM
distribution among the slots. The timeslots are evenly divided into three
groups of 128 timeslots for each of the slot sets. Therefore, slots 1-4 share 128
time slots, slots 5-8 share an additional 128 timeslots, and slots 9-10 share the
last 128 timeslots. Distribute
heavy consumer
cards (cards with a large number
of ports: 30Tipx, PRI-30ipx, T1ipx, PRI-23ipx, UDTipx, or UGWipx with MG-30
or MG-60 units) among the PCM groups evenly.
„
Distribute trunk interface cards (4T-Cipx, 8T-Cipx, 4T-CIDipx, 8T-CIDipx,
4TEMipx, 4TMRipx, 4TWLipx, 4TBRipx, 8TBRipx, 30Tipx, 30Tipx, PRI-30ipx,
UDTipx, PRI-23ipx, and T1ipx) evenly among all cages in the system, rather
than concentrate trunk interface cards in one cage. This practice ensures that
the failure of a single cage will have minimal impact to trunk service.
„
Place Digital Trunk Interface cards in card slots 4 and/or 5. Slots 4 and 5 are
wired as the primary and secondary external clock source, respectively. The
cards inserted in these slots can be used to synchronize the Coral IPx system
clock with a network clock signal derived from a digital trunk circuit.

If no other convention exists, refer to
page 10-1, Peripheral Card Installation
and
Coral Service and Peripheral Cards Installation Manual .
2. If IPx 800X expansion cages are installed determine the position of service and
peripheral interface cards that will be inserted into card slots 1 through 12.
Observe any order previously directed by a system designer or any established
convention of the distributor. The card placement diagrams,
