4-10 Operator Features
Use these instructions only if the system has a QCC with a Direct Station
Selector (DSS).
The factory setting for Extended Call Completion is automatic. This allows QCC
operators with a DSS to extend (transfer) calls by pressing a DSS button. The
operator does not have to press the Release button to complete the call
extending procedure. With automatic release, the operator cannot announce
transferred calls.
You can change the setting to manual completion; the QCC operator must press
the Release button when using a DSS button to extend a call.
Planning Form Instructions
Under the "Extended Call Completion" heading on Form 6a:
1 . Check "Automatic completion" to keep the factory setting.
2 . Check "Manual completion" if the operator must use the release button to
extend calls.
Return Ring determines the number of rings before an unanswered, extended
call is returned to the QCC queue (or QCC Message Center position). The
factory setting is 4 rings. You can change the setting to 1 to 15 rings.
Planning Form Instructions
Under the "Return Ring" heading on Form 6a:
1 .
Check "4 rings" to keep the factory setting.
2 . Check the second box to change the factory setting. Write the number of

Position Busy Backup allows you to assign another telephone to receive calls
when all QCC operator consoles are in a position busy (Backup On) mode. Only
a calling group can be assigned as a backup for a QCC operator position.
The factory setting is that no backup is designated. If you decide not to
designate a backup, the system will not allow the last available operator position
to go into the position busy state.
