CHAPTER 1
APRIL, 1990
NIGHT CHIME(S)
control is provided when the
system is equipped with an ECR-E ETU. The ECR-E
ETU contains ten relays. Three of these relays (one
per tenant) can be programmed to provide closures
when incoming CO/PBX calls are received in the Night
Mode. The
Night Chime
feature is used after normal
working hours to alert night personal of incoming
outside calls. Locally provided external bells and/or
amplifiers are controlled by the system. ANA, DIT or
DID trunks will not activate the
Night Chime
relay(s).
NIGHT TRANSFER
is a function controlled only by
the
Attendant Positions
(with or without
DSSIBLF
Consoles). When an Attendant sets the system into
Night Mode,
it provides a change from the
Day Mode
ring assignment and enables the
Night Call Pickup
and ANA features (if so programmed), in systems
supported by a CPU-EB2 (or higher revision level)
ETU.
OFF-HOOK VOICE ANNOUNCEMENT
can be
provided to any Multiline Terminal (except ETE-8( )
and ETE-16-2) with the installation of the DPA-E
Unit. The DPA-E Unit provides a Multiline Terminal
with a secondary voice path, which allows that station
to receive a
Voice Announcement
while on a handset
call with someone else. This requires the Multiline
Terminal to be supported by an ESI-EB ETU (located
in any of the first three CCUs), as well as being
programmed as a
Dual Path
terminal.
OFF-HOOK RINGING
allows a Multiline Terminal
user to hear when an incoming call is signaling while
the Multiline Terminal handset is in use. The off-hook
ring is provided at a reduced level. This feature can be
disabled in programming if not desired.
OFF-PREMISES EXTENSION
is provided by the
connection of a standard Single Line Telephone
(DTMF) remotely located from the main installation
site, to access the system’s features with the same
capabilities as an on premises Single Line Telephone.
Locally provided Dial Long Line (DLL) equipment is
required for this feature.
PC VOICE DIALING
allows the system user to dial
telephone numbers for voice calls from the PC
Keyboard. Modem Pooling is used in conjunction with
this feature.
PC Voice Dialing and Modem Reserve capabilities can
be allowed through system programming if the system
is supported with a CPU-EB3 (V3.05) ETU (or higher
revision level). PC Voice Dialing requires the use of a
MFR-EA ETU.
100 -
Each modem (four maximum) must be able to respond
to Keyboard commands such as the HAYES@
Commandset, provide auto answer, and must be
supported by an SLI-E ( ) ETU port, a Multiline 1
Terminal with LCD (equipped with a DTA-E Unit),
and supported by an ES&EB ETU port.
POOLED LINE
allows multiple trunks to be assigned
to a multiline Terminal’s line key for incoming and
outgoing calls. This feature allows station users to
answer and originate outside calls for any line
belonging to a Pooled Line Group with one Pooled Line
key. Up to eight Pooled Line Groups can be assigned
per system. This feature requires the support of a
CPU-EB3 (or higher revision level) ETU.
POWER FAILURE TRANSFER
ensures that a
customer can always have access to the central office
network, even during a commercial power outage.
This feature requires the use of Single Line Telephones
supported by SLI-EB ETUs. If power fails to support
the Electra Mark11 CCUs, the CO Tip and Ring are
automatically transferred to the Tip and Ring of a
preselected (and cross connected) Single Line
Telephone. These SLTs may function in the system
during normal operation, or only during power failure,
depending upon the customer requirements.
PRIME LINE ASSIGNMENT
simplifies the use of
the system by providing automatic selection of a line.
When a Multiline Terminal, programmed for
Prime
Line Assignment,
goes off-hook, the assigned extension
or outside line key is seized automatically. This
feature seizes the line when it is IDLE. When a Single
Line Telephone, programmed for
CO Prime Line
Assignment,
goes off-hook the assigned CO line is
seized. To release this line and obtain a new internal
dial tone, hookflash, and dial the preprogrammed
release code [when the system is supported with a
CPU-EBB (or higher revision level) ETU].
Variations of this feature are accomplished when the
system is programmed for
Prime Line
pickup for
incoming calls, or the terminal is programmed for
Ringing Line Preference
and
Prime Line.
PRIVACY ON ALL CALLS
provides the secure
knowledge that no one can listen to your ongoing
conversation. Only the person holding a conversation
can allow another party to enter the conversation (via
Add-On Conference).
All lines in the system are
provided with complete
Privacy.
PRIVATE LINES
can be assigned via the
Flexible
Line Assignment
feature. Restriction assignments can
be used to assure that a line is made private.
