Configure dialing plans within the corporate network 233
Use the traditional PSTN for general modem traffic
General modem traffic (for example, V.36, V.90) cannot be supported on
ITG. The Meridian 1/CS 1000M routing controls must be configured to route
modem traffic over circuit-switched trunks instead of over IP Trunk 3.01
(and later).
Use the ESN TGAR, NCOS, and facility restr iction levels to keep general
modem traffic off of the IP Trunk 3.01 (and later) route. Use caution before
setting TGAR=YES in the ESN block in LD 86 since this will impact all trunk
access for ESN calls. New Flexible Code Restriction (NFCR) can be used
to block direct access to trunk routes for stations with CLS = CTD.
When adding IP Trunk 3.01 (and later) trunks to an existing Meridian 1/CS
1000M system, changes to ESN translation should be made last, after the
IP Trunk 3.01 (and later) dialing plan and the entire IP Trunk 3.01 (and later)
network is tested with calls dialed using the Route Access Code. In LD 16,
for prompt CTYP, set to appropriate call type for the IP Trunk 3.01 (and later)
node numbering plan in order to make test calls using ACOD. After the
correct operation of the entire IP Trunk 3.01 (and later) network has been
verified, ESN translations that are intended to be routed through IP Trunk
3.01 (and later) TIE trunks are then changed so as to use the new RLI.
Use the following overlay tables to configure ESN, Route List Block with Step
Back on Congestion on ISDN, dialing plan, and Co-ordinated Dialing Plan.

Set TGAR = YES if required to block non-fax modem traffic
from the IP Trunk 3.01 (and later) route.
Caution: This will impact all trunk access for ESN calls.
TGAR and TARG values must be carefully coordinated for
all stations, trunks, and routes when setting TGAR = YES
in the ESN block.
