820.4 HARDWARE REQUIREMENTS

Connection of a Voice Mail system, dictation equipment, SLTs, or modems to the Electra Mark11 System requires a VMI-E ETU and an RSG-E Unit that supports the CCU in which the VMI-E ETU is installed.

If the Voice Mail equipment to be connected provides call placement and/or in-band message wait signaling capability, an MFR-EA ETU is also required.

The RSG-E Unit and the MFR-EA ETU may be shared with single line telephones and other devices installed in the system.

One VMI-E ETU can be installed in any interface slot.

NOTE: Two VMI-E ETUs can be installed in a system that has a CPU-EC4 (or higher revision level) ETU.

820.5 HARDWARE INSTALLATION

Refer to Chapter 2 of this manual for information regarding hardware installation.

SECTION 830

PROGRAMMING

830.1 REQUIRED PROGRAMMING

Memory Blocks 4B8 and 4B9 are used to assign signal timing parameters to each pair of channels of the VMI-E ETUs.

Refer to the specifications of the Voice Mail or dictation equipment being connected to determine any changes necessary for proper operation. Chapter 6 of

this manual (Engineering Technical Information (ETIs) bulletins) are issued to assist in the connection of specific equipment.

Memory Block 4Cl - CARD INTERFACE SLOT ASSIGNMENT; can be used to assign the VMI-E ETU to the appropriate CCU interface slot.

When installing a VMI-E ETU in a vacant interface

slot that has not been previously assigned, no

additional programming of this memory block is required. However, if a VMI-E ETU is added to an existing system, and the interface slot was previously occupied by a different type ETU, it is necessary to reassign the CCU interface slot, using this memory block, after the VMI-E ETU has been installed.

830.2 RECOMMENDED PROGRAMMING

Memory Block lC3 - DSS/BLF BUTTON : ‘1

ASSIGNMENT. It is recommended that VMI-E ETU

extension appearances be programmed into the attendant’s DSS/BLF to permit easy access for calls and transfers to the Voice Mail or dictation equipment.

NOTE: Before programming Memory Block lC3, Memory Block 1Cl - DSS/BLF to Attendant Assignment should already be. programmed.

Any change made to this memory block will

erase any previous assignments made in Memory Block lC3, and will have to be reentered.

Memory Block 2B4 - DIT ASSIGNMENT can assign specific trunks directly to a specific VMI port, so the Voice Mail system can be accessed directly by an external party. This Memory Block can also be used to assign specific trunks to a specific VMI port when the system is put into the Night Mode (ANA).

Memory Block 2B8 - VMI ASSIGNMENT is used to

assign VMI-E ETU channels as Single Line Telephones or Voice Mail ports. In addition, this memory block can be programmed to send or not send automatic in-band DTMF signaling to the Voice Mail system, by corresponding extension numbers of the station number that has been Call Forwarded to that Voice Mail Port.

Memory Block 2C4 - VOICE MAIL HUNT GROUP ASSIGNMENT is used to assign up to four VMI-E ETU extension numbers to the Voice Mail hunt group. After this is done, when the Voice Mail Hunt Group Access Code (Default 63) is dialed internally, the system will hunt for the first Idle extension within the hunt group.

Memory Block 2D2 - SYSTEM TIME BASE ASSIGNMENT II can be used to assign a time delay before the in-band DTMF signaling for VMI forwarded calls are sent.

Memory Block 3Cl - TELEPHONE NAME ASSIGNMENT can be used to name each VMI-E ETU channel. When Message Waiting displays are sent from a Voice Mail system, this name will be included in the Message Display that is sent to a Multiline Terminal with a display (Example: MAIL).

Memory Block 3B5 to 3B8 - STATION HUNT ASSIGNMENT is used to assign station, Virtual, and/or VMI-E ETU extension numbers to a station hunt group. Each station hunt group can be assigned up to sixteen extensions of which eight can be VMI-E ETU extension numbers.
