CHAPTER 1
APRIL, 1990
Speed Dial memories, Night Chimes, and Night Call
Pickup can be provided.
TONE OVERRIDE allows station users to signal an
in-use extension they want to talk to. Once alerted, a
Multiline Terminal user can immediately answer the
Override by depressing the Answer Key (placing the
existing caller on Consultation Hold). Single Line
Telephones can place their existing call on Exclusive
Hold and answer the override call.
TRUNK/MFR TEST and BUSY OUT; Attendant
Positions have the ability to test and busy out trunk
and MFR circuits, with the support of a CPU-EB (or
higher revision level) ETU. Each individual trunk
circuit can be examined to determine if it is in good
working order. If a particular trunk is found to be
inoperable, the attendant can busy it out. When the
problem is corrected, the trunk circuit can be restored.
Additionally, Single Line Telephones can be used to
test the dual tone multi-frequency receiver circuits (on
the MFR-EA ETUs) to determine if they are
operational. If a problem is detected, an attendant can
busy out the defective circuit. Once the problem is
corrected, the attendant can restore the circuit.
TRUNK NAME ASSIGNMENT allows names to be
assigned (via programming) to each trunk of the
Electra Mark11 System. These names appear on the
Multiline Terminal’s LCD when a line belonging to
one of these trunks receives an outside transferred call,
an E&M Tie Line, Direct Inward Dialing (DID), Direct
Inward Termination (DIT) call or ANA. When
receiving an outside transferred call or receiving an
E&M Tie Line, DIT, or DID call at a Multiline
Terminal, the name assigned to the trunk, to which
this line belongs, appears in the LCD.
Each of the forty available trunks can be assigned a
name. The assigned name cannot be more than eight
characters (including spaces). By default, CO LINE is
assigned for all trunks. The trunk name is not
provided on the LCD when receiving an outside call
appearing at a direct outside line key on the Multiline
Terminal or when originating an outside call. A CPU-
EC4 (or higher revision level) ETU is required to
support this feature.
TRUNK to TRUNK TRANSFER allows any station
user the ability to establish a Trunk to Trunk Transfer
and then hang up, without dropping either call. The
Trunk to Trunk Transfer can be between two central
office calls, two E&M Tie Line calls, or any
combination of the two. This feature does not require
the use of a conference circuit. A disconnect signal
must be provided to the Electra Mark II. A CPU-EBB
(or higher revision level) ETU is required to support
this feature.
TRUNK QUEUING allows station users to increase
their call processing efficiency in a high traffic
environment. The system must be supported with a
CPU-EB (or higher revision level) ETU, and the
stations dial access to the busy trunk group cannot be
via LCR.
Station users who are denied a trunk or Tie Line (after
dial access via an extension) when all trunks in the
trunk group are busy, can queue onto the trunk group
by a dial access code. When a trunk in that trunk
group becomes idle, the system reserves it and initiates
a Recall indication to the queuing station’s primary
extension (when station and extension are idle).
TWO COLOR LEDs are provided on the line keys of
all Multiline Terminals [except the ETE-B( )I to more
rapidly distinguish between the status of lines. A
green LED provides the Multiline Terminal user with
such status information as I-Hold, I-Use and Hold
Recall. A red LED provides indication of all other line
status. The DSSIBLF Console is also provided with
two color LEDs, on buttons programmed for direct
access to extensions.
UNIFORM CALL DISTRIBUTION (UCD) feature
permits incoming DIT and DID calls to terminate in a
prearranged group in the order of their arrival.
Incoming calls are distributed uniformly between all
members of the UCD group so that new calls terminate
at the next idle station.
A call to a UCD group in which all extensions are busy
may be overflowed to another designated group or
extension.
When an incoming DIT call to a UCD group
encounters all UCD extensions busy or no answer, the
call is queued and receives a recorded announcement
after a predetermined interval. A CPU-EB3 (or higher
revision level) ETU is required to support this feature.
UNIVERSAL PORTS provide complete flexibility for
installation and cost savings for the end-user. The
Electra Mark11 System allows the installation of any
type interface circuit board into any interface slot.
This allows maximum utilization of the CCUs,
resulting in minimal hardware costs.
USER PROGRAMMING CAPABILITY reduces
installer time and involvement and allows the user to
make any required changes while the system retains
its versatility. Each Multiline Terminal user can
program such features as Off-Hook Ringing, internal
100 - 15
