MAINTENANCE ADMINISTRATION TERMINAL [M-18].
6. While LINE LOAD CONTROL is activated, a single line station will receive busy tone (or the display for
the D
term
is blank) when going off-hook.
7. A station in LINE LOAD CONTROL [L-11, 20, 21] can receive incoming calls.
8. Incoming calls terminated via CCIS/ISDN trunks are not restricted.
Interactions
1. Calls in progress are not affected when this feature is activated.

A designated key cannot be assigned at the Attendant Console to control this feature.

LOAD CONTROL is active.
