PE-BCHL (PRI Endpoint Port)
A PRI Endpoint provides ISDN-PRI (Primary Rate Interface) connections for
customers with applic ation equipment or terminal ad apters that terminate
ISDN-PRI. The equipment or terminal adapters are connec ted to the switch via
the UDS1 interface circuit pac k. PRI Endpoint Port (PE-BCHL) maintenance
provides a strategy to maintain PRI Endpoint Port hardware circuitry on the UDS1
circuit pack. The maintenanc e strategy involves logging PRI Endpoint Port
hardware errors, running tests for p ort initialization, periodic and scheduled
maintenance, system technic ian-demanded tests, and alarm escalation and
resolution.

Wideband Switching

The Wideband Switching capability supports end-to-end connectivity between
customer endpoints at d ata rates from 128 to 1536 kbps over T1 facilities and to
1984 kbps over E1 facilities. DEFINITY switching cap abilities are extended to
support wideb and calls comp rised of multiple DS0s that are switched end-to-end
as a single entity.
The Wideband Switching capability is designed for ISDN application equipment
(for example, ISDN video code cs), but it retains provisions for non-ISDN
application eq uipment by using PRI terminal adap ters. In the same sense that a
DEFINITY data module acts as a DCP or BRI terminal adapter between end point
data (for example, V.35) and dialing (for example, RS-366) interfaces and a DCP
interface, a PRI terminal adapter ac ts as a wideband terminal ad apter between
endpoint data and dialing interfaces and DEFINITY’s line-side ISDN PRI
interface.
The Wideband Switching Capab ility introduces PRI Endpoints on DEFINITY
line-side interfaces. A PRI Endpoint c onsists of one or more contiguous
B-channels on a line-side T1 or E1 ISDN PRI facility, and it has an extension
number. Endpoints initiate and receive calls using ISDN SETUP messages that
indicate the data rate and specific B-c hannels to be used, and they
communicate all other ca ll status information via standard ISDN messages. Any
DEFINITY IS DN signaling set (for example, AT&T, CCITT, E CMA) may be used for
a line-side ISDNPRI facility.
