PE-BCHL (PRI Endpoint Port)
Issue 1 June 2005 1773
PE-BCHL (PRI Endpoint Port)
S8700 | 8710 / S8500
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. 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 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
a line-side ISDN-PRI interface. Wideband switching introduces PRI endpoints on 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 ISDN signaling
set such as Avaya, CCITT, or ECMA may be used for a line-side ISDN-PRI facility.
