WAE-PORT (Wideband Access
Endpoint Port)
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.
The Wideband Switching capability 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 Universal DS1 circuit pack
(TN464C). These endpoints are administered as Access Endpoints, and they
have no signaling interface to the switch. Instead, 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 UDS1 circuit pack (TN464C) facility
are separate and distinct within the facility, and the endpoint application
equipment must be administered to send and receive the correct data rate over
the correct DS0s. All Administered Connections originating from Access
Endpoints use the entire bandwidth administered for the Access Endpoint. An
incoming call of a different data rate then that administered for the Access
Endpoint cannot be routed to the Access Endpoint.
Although Wideband Access Endpoints are used primarily for line-side facilities,
these endpoints can also be administered on network DS1 facilities to connect
DEFINITY to non-switched network services, such as the AT&T fractional T-1
service. An example of this is the AT&T 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
