There is no need to send digits to the RAC. It is capable of auto-detecting the protocol

being terminated on it, for example ISDN 56Kbs bsor Modem, and PPP, MLPP. Some

other RAS devices need a special DN or a prefix (APFX) to indicate the protocol expected

for the termination. In some instances you may want to override his capability for special

CLI manual regarding “Session Parameter Blocks” or SPBs.

If you expect to send digits to the RAC you will need to set the “dnis” parameter in the

RAC WAN configuration. The “dnis” parameter sets the RAC to expect digits to be sent to

the trunk on a seizure. If “dnis” set to zero and numbers are sent, you will likely get a

“TRK018” from the DMS-10. This is because the RAC will not wait for the digits and will

answer before the DMS-10 is done sending the digits.

Once the Trunk Group and Route are set. The the chosen DN will need to be set to termi-

nate on the trunk group. This can be done by either translating or by intercepting the DN

and sending it to a screen with the route to the trunk group.

5.4.2 ISDN PRI LTG Setup

PRI setup is nearly identical to setting up a DCM trunk. PRI requires you to set up a Line

Trunk Group (LTG) which is automatically done in overlay PRI when the PRI is assigned.

Below is an example of a typical LTG for a RAC.

NUM 2

APPL PRI

TGTP OUT

Note: If digits are being sent to the RAC on a A/B bit Trunk, the WAN “dnis”

parameter on the RAC must be set with the number of digits. Otherwise

the RAC will answer before the number is sent resulting in a DMS-10

“TRK018”.
