ISDN-PLK (ISDN-PRI Signaling Link Port)
The ISDN-PRI S ignaling Link Port is the port on a TN464C or later UDS1 Interface
circuit pack that carries D-channel messages to the processor. The ISDN-PRI
interface uses out-of-band signaling as opp osed to robbe d-bit, in-band
signaling. This port c an be used as an interfac e to the TDM bus or to the Packet
bus.
The B-channels associated with a ISDN-PRI D-channel can use p orts on the
same circuit pac k or ports on other TN464C or later or TN767 DS1 Interface
circuit packs (The TN722 cannot b e used for this app lication.)
In a 32-channel system (see Figure 3-21), the DS1 ISDN Trunk or PRI endpoint
port (B-channels) may use any of the p orts 1-15 or 17-31, but the ISDN-PRI
Signaling Link Port must be the 16th por t on the TN464C (or higher) circuit p ack.
In certain configurat ions (NFAS), the 16th port may be used as a B-channel.
Refer to the ‘‘ISDN- SGR (ISDN -PRI Sig nali ng Gro up) ’’ Maintenance
documentation for further d etails.
