6-18 Setting up Meridian Mail security
TGAR/TARG and CLS interaction
Standard 1.0 System Administration Guide January 1998
In this illustration, the following occurs:
• User C dials access code to CO trunk group, followed by
555-6100.
• Meridian 1 checks Trunk Access Restriction Group to see
if user has access to CO trunks.
User C does.
• Meridian 1 checks CLS (SRE) to see if user can make a
local call.
User C cannot make a local call.
• Call is not allowed through CLS.
In summary, when a user attempts to access a trunk route, the
Meridian 1 compares the TGAR assignment against the list of
denied TARGs associated with the route that the user is trying
to access. If the TARG is not listed, the Meridian 1 then uses the
CLS assignment to determine call eligibility.
The system uses the most restrictive assignment, CLS or
TGAR, to determine call eligibility when a user is attempting to
place a call by way of direct access to trunk facilities.
