message mode, the associated green LED also provides the Attendant with the status of messages left for busy or unattended stations.

Up to two DSSIBLF Consoles can be set to function

with an Attendant Position. Up to three Attendant Positions can be provided with two DSSIBLF Consoles each. The totals are six DSSIBLF Consoles associated with four Attendant Positions. The number of CO Add- On Modules will also affect the six console maximum.

DSS/BLF RECALL with station identification provides the originating Attendants’ LCD with the line key number that was transferred or camped on, as well as the station number of the station that did not

answer the Transfer or Camp-On.This allows the

Attendant to respond and address the recall quickly and efficiently.

The ELAPSED CALL TIMER is a counter which is shown on the LCD of a Multiline Terminal engaged in an outside call. This timer provides a constant reminder of the ongoing call’s length (see Figure 100-7 LCD with elapsed call time).

E&M TIE LINES are accommodated by the TLI-E or TLI-EB ETUs. Tie Lines can be any combination of loop dial (TLI-E ETU only), 2 wire, or 4 wire Type I or Type V E&M signaling. Tie lines must be dial pulse if

terminated on a TLI-E ETU. If terminated on a TLI- EB ETU, they can be DTMF or Dial Pulse. Incoming Tie Line calls can access other outside lines to make calls or to access other systems via Uniform

Numbering Networking, if the system is supported by a CPU-EB2 (or higher revision level) ETU.

EQUAL ACCESS ACCOMMODATION permits the Speed Dial memories and Code Restriction processes to allow connection of CO lines that provide access to Specialized Common Carriers (SCC!).

EXTERNAL TONE RINGING (four tones) is

provided by the ECR-E ETU. The ECR-E ETU contains 10 relays, 7 of these relays are programmable for External Tone Ringing (common audible), Night

Chime control, or Delay Announcement start control. Four of the 7 relays can be programmed for common

audible with different interruption patterns including a continuous closure. When connected to a locally

provided call alerting device (loud bell ringer), this feature provides for wide area coverage or loud ringing for noisy locations.

EXTERNAL ZONE PAGING (WITH MEET ME)

enables system users to quickly, and easily locate and communicate with each other. The system provides the ability to set up three zones (plus all zones) of External Paging with the optional ECR-E ETU (and locally provided amplifier, speakers and relays). With the page Meet-Me feature, the Electra Mark11 System allows any station in the system the ability to answer a page, at which time the paging circuit is released and is again available for paging.

FLEXIBLE LINE ASSIGNMENT provides the ability to assign any (except for each Multiline Terminal’s own primary extension) line key to outside lines, appearances of other extension lines, Save and Repeat, Data Transmit, Data Receive, and Do Not Disturb features.

The Electra MarkII’s FLEXIBLE NUMBERING PLAN is assigned by the resident system program,

when the system is first initialized. With few

exceptions the Numbering Plan can be altered for

customer requirements via system programming. Available within the Numbering Plan is the Uniform

Numbering Network for multi-location customers with Electra Mark11 Systems, each system must be

supported by a CPU-EB2(or higher revision level) ETU. This allows all station users, in a network of Electra Mark11 Systems, to dial each station directly without the need of an Attendant to transfer the call.

FLEXIBLE RINGING ASSIGNMENT provides ring tone signals to stations that have an appearance of the CO/PBX or extension line being called. Separate ringing assignments can be set for DAY MODE and

NIGHT MODE.

FLEXIBLE TIMEOUTS provide the ability for the

system to be altered, via programming, to meet the customer’s needs. Standard timeouts are set by the resident system program upon first initialization.

FULL HANDSFREE OPERATION is an optional feature that can be accomplished in either of two methods:

1.Installation of the HFU-E Unit into an LCD equipped Multiline Terminal.

2.Installation of an ADA-E Unit into any Multiline Terminal with a qualified speakerphone (locally provided) connected.
