WAE-PORT (Wideband Access Endpoint Port)
Wideband Switching sup ports end-to-end c onnectivity between cust omer
endpoints at data rates from 128 to 1536 kbps over T1 facilities and to 1984 kbps
over E1 facilities. DEFINITY switching capabilities are extend ed to support
wideband c alls comprised of multip le DS0s that are switched end-to-end as a
single entity.
Wideband Switching extend s the Administered Connect ions feature to include
non-signaling wideb and access endp oints. Endpoint applic ation equipment with
direct T1 or E1 interfaces may connec t directly to the switch’s line- side facilities;
application eq uipment without T1 or E1 interfaces requires a terminal ad apter
such as a DSU/CSU. The terminal adapter or endp oint application eq uipment is
connected to the TN464C Universal DS1 circ uit pack.
These endpoints are administered as wi deband acc ess endpoints and have no
signaling interface t o switch; they simply transmit and rec eive data. (Some
applications d etect and respond to the presence or absence of d ata). Calls are
initiated from these endpoints us ing the Administered Connect ions feature.
Multiple access end points on one line-side UDS1 circu it pack facility are
separate and distinc t within the facility. Endpoint applic ation equipment must be
administered to send and receive the correct data rate over the c orrect DS0s. All
Administered Connections orig inating from wideband access endp oints use the
entire bandwidth ad ministered for the endpoint. An inc oming 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 b e administered on network DS1 facilities to c onnect
DEFINITY to non-switched network services, such as the Luce nt fractional T-1
service. An example of this is the Luc ent Static Integrated Network Ac cess,
where a trunk grou p to AT&T 4 ESS Switc hed Ser vice s share s an ac ces s T-1
facility with a Wideband Ac cess Endpoint. In this cas e, the Wideband Acc ess
Endpoint is connected to the AT&T fractional T-1 service, and it does not
terminate on local endp oint equipment but is c onnected to a far-end CPE (for
example, another DEFINITY PBX) via the dedicated fractional T-1. All Wideband
Access Endpoint func tionality and operation is id entical on both line-side and
