T1 Switched 56 service provides high speed digital data services (up to 56-kbps
per channel) to the network as well as digital Tie trunk services. This allows you to
use your T1 facilities for basic digital data and file transfer needs as well as more
sophisticated personal and/or group video conferencing.
NOTES:
1. T1 Switched 56 service is supported only in Hybrid/PBX or Key mode.
2. Incoming data calls that attempt to route to busy data endpoints,
unassigned Dial Plan numbers, or ports that are not equipped with data
endpoints will not be connected.
This section contains instructions for configuring those T1 Switched 56 options
that apply to the T1 network interface. For information specific to the digital Tie
trunk planning, refer to the
The following options are covered in this section:
Incoming Routing
Signaling
After completing the procedure for filling in the module information on Form 3b,
pages 1 and 2, continue to the next section to fill in T1 Switched 56 options.
Planning Form Instructions
1. Select an Incoming Routing Method. This also assigns the Incoming
Signaling Type.
2. If Dial Plan Routing was selected, you may have to manipulate the
incoming digits by absorbing, deleting, or adding digits. This is because, in
many cases, the digits that are sent by the service provider may not match
the administered Dial Plan. Enter the following information:
''Tie Trunks''
— Line Appearance Routing (incoming services)
— Dial Plan routing (incoming services; Hybrid/PBX mode only)
Line Appearance Routing (default). When selected, incoming data
calls are typically terminated at a data extension/endpoint that has a
DFT or DPT appearance. The call may also terminate at a data
extension/endpoint in a DGC group. This option sets the incoming
signaling type to Auto.
Dial Plan Routing. When selected, incoming data calls are routed
by Dial Plan and may terminate to an SA button on any data
extension within the system. When routing by dial plan, the incoming
signaling type options are Wink Start and Delay Start.
Expected Number of Digits. Enter the expected number of digits
(1–4). The factory setting is 3.
