WAE-PORT (Wideband Access
Endpoint Port)
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. DEFINITY 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 TN464C Universal DS1 circuit pack.
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 UDS1 circuit pack 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
DEFINITY to non-switched network services, such as the Lucent fractional T-1
service. An example of this is the Lucent 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 DEFINITY PBX) via the dedicated fractional T-1. All Wideband
Access Endpoint functionality and operation is identical on both line-side and
