Hardware Installation Procedure
Card slots 3 through 18 are Universal I/O slots, accepting any Shared Service or
Peripheral Interface card type.
Determine the position of Shared Service and Peripheral Interface cards that

are to be inserted into card slots 1 through 18. Observe any order previously
directed by a System Designer or any established convention of the distributor.
The Card Placement Diagram,
Figure 2-13 for Odd Numbered Shelves, may be used as a worksheet by the
System Designer to establish card placement prior to installation. Refer to
Table 2-5 to determine Shared Service and Peripheral Interface card types.
Up to two PB-ATS cards are installed in Slots 1 and 2 of every even

peripheral shelf, see
Shared Service cards, see

every odd numbered peripheral shelf.
Distribute trunk interface cards (4ALS, 8ALS, 8BID, 8DID, 4GID, 4T, 8T,

4/8T-C, 4/8T-CID, 4TEM, 4TMR, 4TPF, 8TPF, DPC, 4TBR, 8TBR, 30T,
30TM, 30T/x, PRI23, PRI30, 2DT, UDT and T1) evenly among all
peripheral shelves in the system, rather than concentrate trunk interface
cards in one or two shelves. This practice ensures that the failure of a single
peripheral shelf has minimal impact to trunk service.
In cabinets with three peripheral shelves (48 card slots), place all single-line

and magneto ports (8SLS, 16SLS, 24SLS, 16SH/S-LL and 8SM cards) on
even numbered peripheral shelves if possible, so that an RPS (Ringer Power
Supply) is not required on the odd numbered peripheral shelf.
Tip:
The 8SA and 24SA cards do not require RPS for industry standard, single
line telephones (SLT). The ringer generator is provided by the 8/24SA card.
If no other convention exists, plan the card placements as follows:
Insert PB-ATS cards in card slots 1 and 2 of each even numbered peripheral

shelf.
Insert Shared Service cards in card slot 1 and 2 of each odd numbered

peripheral shelf.
If synchronization is required, the first two Digital Trunk Interface cards must

be placed in card slot 4 of two even numbered peripheral shelves in the Main
cabinet. The cards inserted in these slots are used to synchronize the Coral
system clock with a network clock signal via a Digital Trunk Circuit, as they
Figure 2-12 for Even Numbered Shelves and
Odd or Even Shelves on page
Table 2-5, can be installed in Slots 1 and 2 of
6-26.
