T1 Routing by Dial Plan
Routing by dial plan is available on Switched 56 services offered on T1 connections.
Service providers offer digit outpulsing for their T1 Switched 56 services. With digit outpulsing, the Central Office sends a number of digits to the MERLIN MAGIX Integrated System. When ordering the service, the System Manager must choose how many digits are to be sent to the communications system. Generally, the default number of outpulsed digits is four; however the System Manager may choose 3-digit outpulsing, which can be accepted by the MERLIN MAGIX Integrated System for Switched 56 services.
In many cases, the digits that are sent from the service provider may not match the MERLIN MAGIX Integrated System dial plan. In these cases, the digits can be manipulated by absorption, deletion, or addition of digits. The System Manager also can use system programming to renumber a block of dial plan numbers on the communications system to match the outpulsed digits.
With this enhancement, multiple telephone numbers can be used on a single T1 Switched 56 line. For example, these could be three ACCUNET Switched 56 Services channels on a T1 line/trunk with 10 different numbers on each channel. This allows 30 different (non-simultaneous) callers with unique numbers to call into the communications system and reach 30 different data extensions.

Most local exchange carriers (LECs) do not offer multiple telephone numbers associated with a single channel. Therefore, routing by dial plan can route calls only to a single data extension for each single telephone number provided by the local exchange carrier Central Office. |
The three settings in the Incoming Routing Table are as follows:
