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 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, and to the 
MM710 DS1 Interface Media Module (

).

Note:

: Although the WAE-PORT MO is provided for a G700 Media Gateway, this 

MO only partially supports the MM710 DS1 Media Module.

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 or MM710 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. Every 
Administered Connection originating from a wideband access endpoint uses the entire 
bandwidth administered for the endpoint. An incoming call with a different data rate than that 
administered for 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
