ISDN-PLK (ISDN-PRI Signaling Link
Port)
The ISDN-PRI Signaling 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 opposed to robbed-bit, in-band
signaling. This port can be used as an interface to the TDM bus or to the Packet
bus.
The B-channels associated with a ISDN-PRI D-channel can use ports on the
same circuit pack or ports on other TN464C or later or TN767 DS1 Interface
circuit packs (The TN722 cannot be used for this application.)
In a 32-channel system (see Figure 3-21
), the DS1 ISDN Trunk or PRI endpoint
port (B-channels) may use any of the ports 1-15 or 17-31, but the ISDN-PRI
Signaling Link Port must be the 16th port on the TN464C (or higher) circuit pack.
In certain configurations (NFAS), the 16th port may be used as a B-channel.
