6-50 Setting up Meridian Mail security
Supplemental Digit Recognition
Standard 1.0 System Administration Guide January 1998
Supplemental Digit Recognition
Description
One type of internal abuse or misuse occurs when callers use
incoming TIE trunks. Callers on TIE trunks sometimes dial the
BARS/NARS access code followed by the whole telephone
number of an internal station.
When using Supplemental Digit Recognition, the Meridian 1
“recognizes” dialing sequences associated with internal calls,
and thus prevents callers from using two trunks to complete an
internal call.
Example
The following figure illustrates how the Supplemental Digit
Recognition feature works.
