CHAPTER 1
APRIL, 1990
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
Electra Mark11 System when an outside party
abandons the call (for this feature to function, the
outside line must provide a timed disconnect signal).
Automatic Release is normally provided with Ground
Start Trunks and E&M Tie lines.
BACKGROUND MUSIC via EXTERNAL
SPEAKERS is used for paging from the Electra
Mark11 System and is interrupted only to those
speakers paged (within a zone). This feature requires a
locally supplied music source, a paging system and
control relays as well as the optional ECR-E ETU.
BACKGROUND MUSIC, via station speakers, can
be provided to all Multiline Terminal users. The
system is designed to accept two separate music
sources. Each user can select either of the music
