PE-BCHL (PRI Endpoint Port)
A PRI Endpoint provides ISDN-PRI (Primary Rate Interface) connections for
customers with application equipment or terminal adapters that terminate
ISDN-PRI. The equipment or terminal adapters are connected to the switch via
the UDS1 interface circuit pack. PRI Endpoint Port (PE-BCHL) maintenance
provides a strategy to maintain PRI Endpoint Port hardware circuitry on the UDS1
circuit pack. The maintenance strategy involves logging PRI Endpoint Port
hardware errors, running tests for port initialization, periodic and scheduled
maintenance, system technician-demanded tests, and alarm escalation and
resolution.

Wideband Switching
The Wideband Switching capability 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.

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.
The Wideband Switching capability is designed for ISDN application equipment
(for example, ISDN video codecs), but it retains provisions for 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 (for example, V.35) and dialing (for example, RS-366) interfaces 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.

The Wideband Switching Capability introduces PRI Endpoints on DEFINITY
line-side interfaces. A PRI Endpoint consists 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-channels to be used, and they
communicate all other call status information via standard ISDN messages. Any
