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.
