ISDN trunk group
Issue 5 October 2002 937555-233-506
■ The D-channel for ISDN-PRI interfaces switches through either the TN765
Processor Interface (PI) circuit pack or the TN778 Packet Control
(PACCON) circuit pack. The D-channel for ISDN-BRI interfaces only
switches through the TN778 Packet Control (PACCON) circuit pack.
NOTE:
You cannot use the TN765 circuit pack with ISDN-BRI interfaces.
■ For DEFINITY R configurations, the D-channel switches through the
TN1655 Packet Interface (PKTINT) circuit pack.
■ A TN780 or TN2182 Tone Clock circuit pack provides synchronization for
the DS1 circuit pack.
NOTE:
The TN767 cannot be used to carry the D-channel if either the TN778
(PACCON) or TN1655 (PKTINT) circuit packs are used to switch
the D-channel. However, in these circumstances, the TN767 can be
used for NFAS interfaces carrying only B-channels.
