296 Defining DN length

Using the Received # length

If you change the DN length of your system, you may need to change the Received # length, which
is what the system uses, in conjunction with the dialing table coding, private and public
networking, and the access codes to determine a route for an incoming call over an auto-answer
trunk.
On systems running the DID telephony template, the Private and Public Received # length is set to
the same length as the DN length for the system. On systems running the PBX telephony template,
the Private and Public Received # length default to 3, unless the DN length is changed during the
Startup procedure.
These digits identify target lines

TIPS: The target line number (for example, line 241) and the Received number for the target line
(for example, Received number: 123 maps to line 241) must be different numbers.
and DASS2 fields" on page
However, the received number can be shorter if network or central office constraints require this.
This number cannot be greater than the system DN length on a networked system using a
coordinated dialing plan (CDP) or a universal dialing plan (UDP). On a standalone system it is
possible that the received number length would be greater than the DN length.
Warning: Decreasing the received number length clears all programmed received digits.
