ISDN-PRI Signaling Link Port Interactions (32-Channel - TN464)
The TN767 DS1 interface is used for 24 channel 1.544 Mbps systems. The
TN464C or later can be used for either 24 or 32 channel systems. The 32-channel
(31 DS0 ch 1 framing channel on a 2.048 Mbps link) are only supported
on TN464 series circuit packs. A description of these circuit packs appears in
DS1-BD or UDS1-BD maintenance documentation.
In a 24-channel system, the DS1 ISDN Trunk or PRI endpoint port (B-channels)
may use any of the first 23 ports. The ISDN-PRI Signaling Link Port must be the
24th port (See
Figure 32 on page 1283
). In certain configurations (NFAS), the
24th port may be used as a B-channel. Refer to the ISDN-PRI Signaling Group
(ISDN-SGR) Maintenance documentation for further details.
Figure Notes:
1. B- and D-channel messages are
routed over the TDM Bus. For
additional reliability, a duplex
D-channel can be administered for
a signaling group and located on a
different TN464C (or higher) circuit
pack.
