Note: Where ground start RLT trunks are used, i.e., a QPC250 at the remote PBX and a
QPC70 at the main PBX, the average attendant response time includes a minimum of
2.5-s delay from the time the RLT is seized at the remote PBX to the time that it is
interpreted as an incoming call at the main PBX.

When the CAS feature is not active, the local attendant at the Remote site
handles all calls that require attendant services. These calls are measured and
recorded in TFC004 at the Remote site. When the CAS feature is active,
TFC004 measurements reflect only calls dialed specifically to the local
attendant. All other calls requiring attendant assistance are directed to the
CAS attendant at the Main location.
At the Main site, TFC004 measurements are recorded in the normal manner.
When the CAS feature is active, calls originating from the Remote site are
treated as incoming trunk calls at the Main site.
