station in the system or network. The ability to
originate or receive Camp-On (a form of Transfer to
busy extensions) is based on the Class of Service
assignment of both stations.
CENTREX RINGING provides two distinctive tone
signals to identify internal CENTREX or PBX
incoming calls from outside calls. Centrex Ringing
requires the support of a CPU-EB3 (or higher revision
level) ETU and a COT-EB ETU.
CLASS OF SERVICE is a programming assignment
to allow or deny access to Camp-On OriginatelReceive,
Call Forward, Operator Restriction, Data Line
Security, Station Lockout, Paging Access (Origin&e),
Trunk to Trunk Transfer, Forced Account Code, and
LCR Priority features. Incoming, Outgoing and Code
Restrictions are assigned separately.
A CLOCK/CALENDAR DISPLAY is provided to all
Electra Mark11 Multiline Terminals with an LCD (see
Figure 100-5 Typical Clock Calendar Display).

Figure 100-5 Typical Clock Calendar Display
This display is on the bottom line of the LCD; ie:
displays the time of day, 07143, the month, SEP, the
date, 04, and the day, WED. This display is only
removed during off Iine programming mode when the
Calculator mode is in use or during certain data
communication operations.
CO ADD-ON MODULE. The EDE-30-( ), Revision B
(or higher level), can be installed and programmed as a
CO Add-On Module to allow an Attendant Position the
ability to have direct access to the system’s forty
maximum outside line terminations. The system’s
maximum of six EDE-30-( ) applies to both (DSSIBLF
and CO Add-On) applications. Only four units can be
utilized as a CO Add-On Module (one per Attendant
Position). The system must also be equipped with a
CPU-EB (or higher revision level) ETU. Lines that
appear at the attendant’s Multiline, Terminal cannot
also appear at the CO Add-On Module.
CO DIGIT RESTRICTION provides the ability to
restrict the number of digits that can be dialed from a
station on a CO line. CO Digit Restriction must be
supported by a CPU-EB3 (or higher revision level)
ETU and is programmable on a per station basis.

CODE/CALL RESTRICTION aids in the ability to
tailor the station dialing restriction to every
customer’s individual needs. The Electra Mark11 offers
an advanced network of restrictions to control outside
calls, based upon area and local office codes. The
restriction feature provides override capability on
trunk group and system speed dial basis and
accommodates Equal Access to secondary common
carriers.
CONSECUTIVE SPEED DIAL simplifies dialing
complicated sequences of numbers such as those used
for some specialized common carriers, credit card, and
other applications. All Electra Mark11 Multiline
Terminals have the capability to Consecutively Speed
Dial, with access to System and Station Speed Dial
memories.
CONSULTATION HOLD offers the Electra Mark11
system user the convenience of originating a call to a
second station in the system from the same line used
for an existing call. This allows the user to consult
with someone while holding the outside party.
Afterwards, the user may initiate a Conference, return
to the outside party, alternate between the two calls
(Broker’s Call), or Transfer the outside party to the
consulted internal party.
DATA COMMUNICATION is made available when
the system is equipped with a CPU-EB (or higher
revision level) ETU and with a DTA-E Unit installed
in each Multiline Terminal (ETE-GD-( ), ETE-16D-( )
and ETE-16K-1) requiring this feature. The DTA-E
Unit provides a terminal user with the capability of
Voice and Data Communication simultaneously.
These data ready Multiline Terminals require ESI-EB
ports, which are associated with the first three CCUs.
DATA LINE SECURITY provides a station with
protection from receiving audible tones (such as Camp-
On or Override) while busy, This prevents disruption
of ongoing data transmission.
DC POWER OPERATION may be desired for its
simplicity of providing standby power. The system can
be powered by a local -48V dc source. When so
required, each CCU must be equipped with a PSE-DD-
1 PSU. This PSU is installed in place of the PSE-AD-1
PSU.
DELAY ANNOUNCEMENT (UCD) occurs when an
incoming DIT call to a UCD group encounters all UCD
extensions busy or receives no answer within a
preprogrammed period of time. 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.
