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.
