Connectivity from the Peripheral Bays

Peripheral bays connect to the main control cabinet with the use of an

interface module on the Peripheral FIM Carrier II card, Peripheral

Interface Module Carrier card (PIMCC), BCC III, or PRI card. The

Peripheral FIM Carrier II card supports a FIM. The PIMCC, BCC III, or

PRI card support a FIM II or a CIM. A FIM II or CIM sits on a PIMCC

when the peripheral cabinet does not have a BCC III.

As a guideline to achieve a P.0001 grade of service (one

failure in 10,000 calls) for a bay connected via a Control

Triple FIM Carrier, the recommended maximum

calls/hour is 500 based on traffic tables. With a typical

call hold time of 2 minutes and 12 seconds the total

Erlang rate is 18.33 (660 CCS) for the whole bay. The

half bay would therefore be 9.17 Erlangs (330 CCS) at

250 calls/hour. It is important that calls be evenly

distributed across all bays.

Remember to use the same distance variant of FIM or FIM II

at both ends of the cable. You can connect a FIM to a FIM II.

Remember that the system sees the PRI card as a separate

bay and therefore a PRI card in a peripheral cabinet must

always have its own interface module (FIM II or CIM).

Remember that the CIM suits co-located systems; not remote

systems. The CIM comes in only one variant. The CIM

supports a distance of up to 30 meters or 100 feet between

cabinets.
