NEC nd-20292 manual TRUNK/MFR Test and Busy OUT Attendant

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
