Primary Rate Interface (PRI) Installation
Description
Your system is compatible with ISDN Primary Rate Interface (PRI) services. The PRI services currently supported include:
●Basic PRI Call Control (BCC).
●Display of incoming caller's number (with software 1.02 or higher and when allowed by the telco).
●Routing in the system based on the number the caller dialed (Called Number Information element).
●ISDN maintenance functions (such as In Service/Out of Service Messaging).
●Speech and 3.1KHz audio.
Conditions
●Each T1/PRI Interface PCB is switch selectable between T1 and PRI operation. For more on T1 trunk- ing, refer to the T1 Trunking feature in your system's Software Manual (P/N 0893200).
Installing the Aspire T1/PRI Interface PCB (P/N 0891009)
System Requirements:
●T1/PRI Interface PCB, P/N 0891009
●Aspire system software: Any Version
●NTCPU (P/N 0891002) with PAL Upgrade (P/N 0891039) OR Enhanced NTCPU (P/N 0891038)
●For DTMF receivers with such options as ANI/DNIS
●CSU/DSU Unit and interconnecting cables (see below)
The T1/PRI PCB has a single 24 channel circuit which you can configure for either T1 trunking or PRI. When set for PRI, each T1/PRI PCB provides 24 PRI (23 B & 1 D) channels with 64K Clear Channel response Each PCB uses a single slot in the system cabinet.
Connecting the T1/PRI Interface PCB requires the following equipment.
•Satellite 931 CSU (P/N 85945)
•External
•T1/PRI Interface PCB (P/N 92060A)
When installed, the T1/PRI Interface PCB uses the first block of 24 consecutive trunks. For example, if you have an 8COIU PCB installed for trunks
