Features
number per B-channel group. The line phone number, which is matched
against the CdPN, is used for routing a call to a specific line that normally
terminates on a Direct Facility Termination (DFT) button.
Routing by Dial Plan is similar in concept to DID. It provides the ability to direct
a call automatically to the proper endpoint for improved call distribution and call
handling. Unlike a DID line, a PRI line programmed for Routing by Dial Plan can
accommodate outgoing calls as well as incoming calls. As with DID operation,
this feature is available only in Hybrid/PBX mode.
Routing by Dial Plan also allows multiple calls to a directory number. This
feature routes concurrent incoming calls to the same telephone number to any
lines in the B-channel group.
For each B-channel group the system can be programmed for either routing by
line appearance or Routing by Dial Plan. With Routing by Dial Plan, the Dial
Plan Routing Table must be programmed to contain a series of patterns, the
number of digits in the CdPN, services on which to match, and a number of
digits to add or delete for each match, in order to route the call to the proper
internal dial plan endpoint.
If a B-channel group is programmed for Routing by Dial Plan, all calls into that
B-channel group are routed in a DID-like manner and will terminate on an SA
button, a single-line telephone, into a calling group queue, or at a Queued Call
Console (QCC). If the digit analysis results in a number for which there is no
match in the Dial Plan Routing Table, the call is routed to the programmed
backup position for unassigned DID calls (normally the primary system operator
or a fast busy tone). Any call into a B-channel group programmed for Routing
by Dial Plan will have its CdPN manipulated according to the Dial Plan Routing
Table before matching it against the internal Dial Plan (to identify an endpoint to
which the call will be delivered). The call must match an entry on the Dial Plan
Routing Table, or it will be refused. If the manipulated CdPN does not match an
internal endpoint, it will receive unassigned DID call treatment. This unassigned
endpoint can be a calling group, a QCC, a telephone, or fast busy tone.
If a fast busy tone is programmed as the routing endpoint for unassigned DID
calls, the call is rejected. This typically causes the network to return intercept
tone rather than fast busy. If the number matches an endpoint that DID calls
are not permitted to reach, for example, pool access codes, group page codes,
line access codes, or the ARS access code, the call is routed to the
programmed endpoint for unassigned DID calls (unless the backup is fast busy
tone).
Routing by Dial Plan
Table 29 is a sample Dial Plan Routing Table. Note that in the sample table all
incoming calls via the MEGACOM 800 service will be delivered to an endpoint
whose Dial Plan number is 1234. Entry 15 would be skipped because “No
Service” is specified.
