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: Inserting
Connector Function
1 and 2
A1 and A2
1 to 19
A1 to A19
Provides a fiber-optic cable interface to an Expansion Interface (EI) circuit
pack in slot 1 1 or a copper cable interface for a DS1 converter
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.
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.
! CAUTION:
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.
