Physical Description

A. 32, 100

(1024/VCIs per VPI)

VPI

The CPX hardware consists of these items (Figure 2–4): CPX shelf (Figure 2–4)

Summary alarm panel (detail, page 2-10)

Line modules—line cards and transition cards for T1 or STS-1 (beginning on page 2-19)

STS-1 Splitter Assembly (when STS-1 equipped) DC Power Supply Fan and Fan modules (page 2-37)

￿DC power distribution panel (page 2-39)

B. 36, 100

C. 38, 100

1. All three have the same VCI.

2. The maximum number of VCIs possible (1,024) divided by the number of VCIs configured (256) equals 4.

3. Pairs A and B yield a result with no remainder when their VPIs (32 and 36, respectively) are divided by the resultant of 1024 divided by 256: 32/4 = 8 with a remainder of 0 and 36/4=9 with a remainder of 0. (Pair C yields a different remainder: 38/4=9, remainder 2. Therefore, it is not in the same group with A and B.)

A maximum 4,096 IADs can be assigned. However, only 63 simultaneously active calls through IAD unlocked ports are allowed in any one IAD Group.

Note

IAD ports can be over-provisioned; however, only 63 can obtain dial tone at one time.

For ￿example, consider three IADs with the VPI/VCI pairs and where the maximum number of VCIs configured for the equipment is 256:

the remainder of the formula is the same for all IADs:
