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 maintenance object monitors the PRI endpoint
port hardware on the UDS1 circuit pack by logging hardware errors, running
tests for port initialization, and running periodic and scheduled maintenance and
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. DEFINITY switching capabilities are extended to 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 DEFINITY 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 DEFINITY’s line-side ISDN PRI interface. Wideband switching
introduces PRI endpoints on DEFINITY 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 DEFINITY ISDN signaling set such
as Lucent, CCITT, or ECMA may be used for a line-side ISDN PRI facility.
Multiple PRI endpoints on one line-side facility are separate and distinct within
the facility. Non-overlapping contiguous sets of B-Channels are associated with
each PRI endpoint, and the endpoint equipment is expected to initiate calls
within these boundaries. The endpoint application equipment must:
