Although Wideband Access Endpoints are used primarily for line-side facilities,
these endpoints can also be administered on network DS1 facilities to connect
S8700 Multi-Connect 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 (for
example, another S8700 Multi-Connect) 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 Universal DS1 interface circuit
pack 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 UDS1 Interface circuit pack is out of service, every port on it is taken
out of service, and a Warning alarm is raised.
