Dial Plan Routing - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Dial Plan Routing

Dial Plan Routing
Dial plan routing provides a way to route incoming calls on a "per B-channel
group" basis. An incoming call is routed by matching the incoming number
(by service, number of digits, and pattern) and then optionally deleting and/or
adding digits to direct the call to a specific endpoint. A service must be
specified; the number of digits and pattern are optional. For example, you can
specify that calls received from a particular area code should be routed to the
specific individual or group responsible for accounts in that area.
Dial plan routing is available in Hybrid/PBX mode only. Key systems route
incoming calls on a per-line basis.
NOTE:
You can enter a service not shown on the Network Service screen by using
the five-digit binary code that represents the service in the Network Facilities
Information Element of ISDN PRI layer three signaling protocol. ( Contact your
service provider for more information about the codes.) See "Miscellaneous
Procedures."
IMPORTANT:
You must program a service before you program any other Dial Plan Routing
function. If you have not programmed a service, complete the procedure
below for the Service option and then repeat the procedure for each optional
function that you want to program.
