Chapter 4, ''Alarms, Errors, and
A PRI endpoint provides ISDN-PRI (Primary Rate Interface) connections
application equipment or terminal adapters that terminate ISDN PRI. The
equipment or terminal adapters are connected to the switch via the TN464C/D
UDS1 interface circuit pack. This MO monitors the PRI endpoint's port hardware
on the UDS1 circuit pack by:
Logging hardware errors
Running tests for port initialization
Running periodic and scheduled maintenance
Executing demand tests
Wideband Switching
Wideband switching supports end-to-end connectivity between customer
endpoints at data rates from 128 to 1536 kbps over T1 facilities and to 1984 kbps
over E1 facilities. S8700 IP Connect switching capabilities support wideband calls
comprised of multiple DS0s that are switched end-to-end as a single entity.
Wideband switching is designed for ISDN application equipment such as ISDN
video codecs, but can also interface to non-ISDN application equipment by using
PRI terminal adapters. In the same sense that a S8700 IP Connect data module
acts as a DCP or BRI terminal adapter between endpoint data such as V.35 and
dialing interfaces such as RS-366 and a DCP interface, a PRI terminal adapter
acts as a wideband terminal adapter between endpoint data and dialing interfaces
and S8700 IP Connect's line-side ISDN-PRI interface. Wideband switching
introduces PRI endpoints on S8700 IP Connect line-side interfaces.
A PRI endpoint has a unique extension number and consists of one or more
contiguous B channels on a line-side T1 or E1 ISDN-PRI facility. Endpoints
initiate and receive calls via ISDN SETUP messages indicating the data rate and
specific B channels to be used, and communicate all other call status information
via standard ISDN messages. Any S8700 IP Connect ISDN signaling set such as
Avaya, CCITT, or ECMA may be used for a line-side ISDN-PRI facility.
