220 Hardware Description and Reference for Avaya Communication Manager
NAA1 fiber-optic cable adaptor
The NAA1 adapter reroutes fiber-optic cable from the front of an ATM circuit pack to the rear of
a CMC1 Media Gateway. The NAA1 fiber-optic cable adaptor looks like a circuit pack, but the
cable is electrically and optically passive.
TN429D incoming call line identification (ICLID)
The TN429 incoming call line identification (ICLID) circuit pack provides eight ports for direct
inward/outward dialing (DIOD) trunks. Each port provides a 2-wire interface to the central office
(CO) public exchange for incoming calls and outgoing calls. The CO provides caller names and
numbers to the circuit pack. The CO displays the names and numbers on digital telephones,
DCP and BRI, that are equipped with a 32-character or a 40-character alphanumeric display. In
the US, the ICLID supports name and number. In Japan, and other countries that comply with
ICLID requirements, the ICLID displays the number only.
This ICLID is required for the Japan ANI feature where the calling number passes through to the
switch. An in-band detector/converter might be required. Contact your Avaya representative for
more information.
The ICLID provides the required CO disconnect functions and the interface to CAMA/E911.
TN433 speech synthesizer
The TN433 speech synthesizer for Italian provides four ports. These ports retrieve fixed
messages for leave word calling, automatic wake up, and attendant console features for the
visually impaired. These fixed messages include good morning, time-of-day, and extension
number. Each of the ports has touchtone detection. The TN433 speech synthesizer has
administrable A- and Mu-Law companding capabilities.
TN436B direct inward dialing trunk (8 ports)
The TN436B direct inward dialing (DID) trunk for Australia provides eight ports for DID. These
ports are independently connected to a public network. Each port is an interface between a
2-wire analog line from a CO and the 4-wire TDM network in the system. The TN436B DID for
Australia has administrable timers.
