Add ISDN — PRI

North American

Use a TN767C/D/E DS1 or a TN464C DS1/E1 circuit pack for the assignment of a signaling link and up to 23 ISDN — PRI Trunk Group members. A TN768, TN780, or TN2182 Tone-Clock circuit pack is required to provide synchronization for the DS1 circuit pack. A TN765 Processor Interface circuit pack is required for use with the TN767C DS1 circuit pack when PRI is activated.

As an option to the TN768 or TN2182 Tone-Clock, a TN780 Tone-Clock circuit pack (installed in the PPN) can interface external Stratum 3 synchronization for DS1 connections.

European

A TN464C DS1/E1 circuit pack is required for the assignment of the 2 signaling channels and up to 30 ISDN—PRI Trunk Group members. Each E1 span provides 32 ports. Except for North American private-network applications, a TN780, TN2182, or TN419B Tone-Clock circuit pack normally provides synchronization for the DS1/E1 circuit pack. A TN765 Processor Interface circuit pack is required for use with the TN464C DS1/E1 circuit pack when PRI is activated.

As an option to the TN2182 or TN419B Tone-Clock, a TN780 Tone-Clock circuit pack (installed in the PPN) can interface external Stratum 3 synchronization for DS1 connections.

Service Interruption

Since the addition of ISDN—PRI requires a service interruption, notify the customer in advance as to when the addition will be carried out.
