Avaya Definity TN464F
DSI/ ISDN PRI Interface Circuit Pack
Avaya Definity TN464 DSI/ ISDN PRI Interface Circuit Pack TN464 F DS1 interface, T1 ( 24 channels) - This circuit pack provides a DSX1-level physical interface to the DS1 facility
The TN464F circuit pack has unpolarized line out ( LO) and line in ( LI) signal lead pairs, The TN464F circuit pack supports DS1 rate digital facility connectivity,
The circuit pack supports CO, Tie, DID, and off-premises stations ( OPS) port types, These port types use the robbed-bit signaling protocol
On DEFINITY CSI and SI Media Servers, this circuit pack supports ISDN-PRI connectivity, For these applications, the signaling D-channel can connect from the TN464 circuit pack to the processor interface by a permanent switched call over the TDM bus
On S8500 and S8700-series Media Servers, this circuit pack does not directly support D-channel signaling and thus does not directly support ISDN-PRI connectivity However, the TN464 circuit can indirectly support D-channel signaling provided that the central office supports nonfacility associated signaling ( NFAS)
In this case, you use NFAS administration on the server, This administration associates the D-channel of another T1/ E1 circuit pack, usually a TN464, with the TN767 circuit pack
The TN464F circuit pack communicates with Avaya IVR, he TN767 also provides the enhanced maintenance capabilities of the 120A channel-service unit ( CSU) and the enhanced integrated channel-service unit ( ICSU)
Note: This circuit pack is not used in a G650 Media Gateway
