206 Hardware Description and Reference for Avaya Communication Manager

The following table describes the connectors in an expansion control carrier.

IP-PNC port network

In an IP-PNC PN, the expansion control carrier is necessary in the A position. It contains a

required TN775 Maintenance circuit pack in the MNTC slot and an IPSI circuit pack in the tone

clock slot. At least one IP Media Processor or IP Media Resource 320 circuit pack is required in

the PN and should be inserted into the A01 position of the expansion control carrier. Additional

IP Media Processors or IP Media Resources may be inserted in any other carriers or slots in the

PN. The other slots in an expansion control cabinet can contain optional port circuit packs.

CAUTION:

CAUTION: Inserting the wrong circuit pack into the A01 slot of the expansion control cabinet

may result in improper call processing. The A01 slot should contain only an

Expansion Interface circuit pack, an IP Media Processor, or an IP Media

Resource 320.

An IP Media Processor or IP Media Resource 320 can be inserted into almost

any slot in the carrier. But in a conversion from a fiber-PNC to an IP-PNC

configuration, one of these circuit packs should be inserted into the A01 slot that

is vacated by removal of the E.I. circuit pack.

Connector Function

1 and 2

A1 and A2

Provides a fiber-optic cable interface to an Expansion Interface (EI) circuit

pack in slot 1

or a copper cable interface for a DS1 converter

1. In systems that use ATM-PNC, the fiber connectors for the OC-3/STM-1 interfaces to the ATM switches

reside on the faceplates of the TN2305 or TN2306 circuit packs.

1 to 19

A1 to A19

25-pair connectors provide interfaces between port circuit packs and the

cross-connect field or fiber transceiver

Auxiliary (AUX) Provides interfaces for customer alarms, attendant console power, and

emergency transfer panels

Terminal Connects a management terminal to the Maintenance circuit pack in an

expansion control carrier

P1 and P2 Provides access to alarm and control circuits. Also, they connect ringing

voltage from the ring generator to the carrier.
