NEC nd-20292 manual Multiline Terminals 100-5

AUTOMATIC CALLBACK allows users to prompt the system to notify them when a busy extension becomes available. After calling a busy extension, set an Automatic Callback by dialing * 1 (as set in default). When both parties are idle, the system signals the originator first, and after answer, the called station.

AUTOMATIC HOLD occurs whenever an attendant, with a DSSIBLF Console (engaged in a call), depresses a DSS extension or paging access button (see Figure 100-4 DSS/BLF). This places the call on NON-

EXCLUSIVE HOLD. This is also true for Multiline Terminal users that have programmed, and depress the Feature Access keys for DSS or paging access. This places the call on Consultation Hold.

AUTOMATIC RELEASE is performed by the
