Modular ICS 7.1 Installer Guide N0130943 02
Routing service replaces a number of tasks that otherwise have
to be done manually, including:
• entering a line pool code
• dialing an access code for a long distance carrier
• deciding which line pool to use according to the time and
day
The installer can set up routing to take advantage of any leased
or discounted routes using information supplied by the
customer. The system itself cannot tell which lines are cheaper
to use.
For Call by Call service selection (PRI only), the installer
defines destination codes for various call types over PRI lines
(e.g. Foreign Exchange, Tie Trunk, and OUTWATS). This
information is then recorded in the routing and dialing plan
section of the Programming Record for the PRI-A pool (and
PRI-B, PRI-C or PRI-D if there are two or more PRI cards).
The user simply dials a number via the intercom button
without entering any special information. For more
information see,
Programming Call by Call service selection
on page 475.
How to use routing to create a uniform dialing plan (UDP) or
coordinated dialing plan (CDP) is explained in
Dialing plans
on page 112.
Plan your routing service before doing any
programming.
Routing affects every call placed in the system
and must be carefully planned to avoid conflicts
and gaps in the programming. Use the tables in
the
Programming Record to design routes and
destination codes, then check for potential
problems before you start programming.
