PE-BCHL (PRI Endpoint Port)
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 Multi-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 Multi-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 Multi-Connect’s line-side ISDN-PRI interface. Wideband
switching introduces PRI endpoints on S8700 Multi-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 Multi-Connect ISDN signaling set such
as Avaya, CCITT, or ECMA may be used for a line-side ISDN-PRI facility.
