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. Communication Manager
switching capabilities are extended to support wideband calls comprised of multiple DS0s that are
switched end-to-end as a single entity.
Wideband Switching extends the Administered Connections feature to include non-signaling wideband
access endpoints. Endpoint application equipment with direct T1 or E1 interfaces may connect directly to
the switch's line-side facilities; application equipment without T1 or E1 interfaces requires a terminal
adapter such as a DSU/CSU. The terminal adapter or endpoint application equipment is connected to the
MM710.
These endpoints are administered as wideband access endpoints and have no signaling interface to
switch; they simply transmit and receive data. (Some applications detect and respond to the presence or
absence of data.) Calls are initiated from these endpoints using the Administered Connections feature.
Multiple access endpoints on one line-side MM-DS1 Media Module facility are separate and distinct
within the facility. Endpoint application equipment must be administered to send and receive the correct
data rate over the correct DS0s. All Administered Connections originating from wideband access
endpoints use the entire bandwidth administered for the endpoint. An incoming call of a different data
rate then that administered of the endpoint cannot be routed to the endpoint.
Although Wideband Access Endpoints are used primarily for line-side facilities, these endpoints can also
be administered on network DS1 facilities to connect Communication Manager to non-switched network
services, such as the Avaya fractional T-1 service. An example of this is the Avaya Static Integrated
Network Access, where a trunk group to AT&T 4ESS Switched Services shares an access T-1 facility
with a Wideband Access Endpoint. In this case, the Wideband Access Endpoint is connected to the AT&T
fractional T-1 service, and it does not terminate on local endpoint equipment but is connected to a far-end
CPE via the dedicated fractional T-1. All Wideband Access Endpoint functionality and operation is
identical on both line-side and network facilities. However, because maintenance capabilities are limited
to the Wideband Access Endpoint interface, and because faults can occur end-to-end, troubleshooting
procedures based on an end-to-end view of the network is required.
Wideband access endpoint port maintenance provides a strategy to maintain a wideband access endpoint
port via a port on the DS1 interface Media Module hardware. The maintenance strategy covers logging
wideband access endpoint port hardware errors, running tests for port initialization, periodic and
scheduled maintenance, demand tests, and alarm escalation and resolution. Two different port service
states are specified in the wideband access endpoint port maintenance:
•
out-of-service: the port is in a deactivated state and cannot be used for calls
•
in-service: the port is in an activated state and can be used for calls
If the DS1 Interface Media Module is out of service, all ports on it are taken out of service and a
Warning alarm is raised.
