Add PRI Over PACCON to R6si
The optional asynchronous packet bus provided by a TN778 Packet Control
circuit pack (rather than the synchronous TDM bus provided by TN765 Processor
Interface circuit packs) can allow TN464 ISDN-PRI interfaces on an R6si system
to communicate with the system’s SPE.

Tone-Clock Circuit Packs
A TN756 Tone Detector/Generator circuit pack cannot be used with PRI Over
PACCON interfaces. Therefore, replace the TN756 circuit pack with both:
PACCON interfaces. Therefore, replace the TN756 circuit pack with both:
■
TN768, TN780, TN419B, or TN2182 Tone-Clock circuit pack
■
TN748B, TN420B, or TN744C Tone Detector circuit pack
NOTE:
If a TN756 tone-detector/generator is removed from the R5si control
cabinet, the TN2182 tone clock should replace this circuit pack. The
TN2182 Tone-Clock serves to replace the tone detector circuits on
the TN756. If using a TN2182, no TN748B is required.

Expansion Interface (EI) Circuit Packs
If a new packet bus is being added to provide PRI Over PACCON for an R6si
system with an EPN, replace every TN776 EI circuit pack in the system with a
TN570 EI circuit pack. The TN570s allow packet-based communication between
the PPN and each EPN in the system.

DS1/E1 Interface Circuit Packs
Like ISDN-PRI using a TN765 Processor Interface, a TN464C (or later) DS1/E1
circuit pack is required to assign a European 32-port E1 interface.

PRI Over PACCON Versus "PRI Over Processor
Interface”

For simpler call processing, Release 6 administration does not allow packet
interface
interface
and
processor interface circuit packs to control ISDN-PRI calls for the
same
system at the
same
time. Therefore, during a PRI Over PACCON addition,
replace every TN767C DS1 circuit pack used to provide a D-channel signaling
for ISDN-PRI with a TN464F DS1 circuit pack. This frees up PI circuits to control
other important links such as DCS, CMS, and AUDIX.

In an R6si system with Non-Facility-Associated Signaling, a TN767C DS1 circuit
pack may still provide B channels for a PRI Over PACCON link as long as each
controlling D channel for the link (primary and optional backup) resides on a
TN464F DS1 circuit pack.
