The purpose of this topic is to provide basic information
about DEFINITY� Centralized Voice Mail—Interswitch Mode Code (CVM—IMC),
including a description of the feature, requirements, installation instructions,
and administration instructions for integrating an INTUITY AUDIX system
into the network.
What Is CVM—IMC?
Centralized Voice Mail—Interswitch
Mode Code provides customers with the ability to network together a
number of small switches that can share one INTUITY AUDIX voice mail
system. The feature uses the mode-code protocol for call transfer and
communications. The set of disparate switches are networked to one switch
hub, which then provides call transfer ability to the INTUITY AUDIX.
See the DEFINITY
R8.3 Network Configuration Example for a sample setup diagram.
The switches that can be integrated
with DEFINITY R8.2 CVM—IMC include:
- DEFINITY ECS R8.2
- ProLogix R3
- DEFINITY BCS Issue 6
DEFINITY R8.3 CVM—IMC adds
networking with these switches:
- MERLIN MAGIX
- MERLIN LEGEND� R6.1 or
7.0
Requirements
The CVM—IMC integration has
these requirements:
- The system operates only
with a DEFINITY ECS Release 8.2 and ProLogix R3. Release 8.3 will
also support MERLIN LEGEND or MERLIN MAGIX systems as endpoints.
- The network maximum capacity
is 10 switches and 450 mailboxes.
- The switch network must
be set up using mode-code transfers.
- The switch network must
be set up in a star configuration. Linear or tandem connections are
not supported.
- The network must use uniform
dialing plan (UDP).
- If the switch network
is all DEFINITY systems, either 4-digit or 5-digit dial plans can
be used.
- If MERLIN LEGEND or
MERLIN MAGIX systems are used in a DEFINITY system network, a 4-digit
dial plan is required.
- The INTUITY AUDIX system.
- On the INTUITY AUDIX system,
the last active port on each analog-line interface card must be reserved
for the message waiting indicator (MWI) interface.
- MWI ports cannot be in
the hunt group.
Before You Start
Before starting to install the
CVM—IMC, complete these items:
- Confirm that the Sales
and Design Support Center (SDSC) has completed their design for the
installation.
- Integrate the switch systems
before starting the INTUITY AUDIX integration. The switch integration's
must be working properly before the calls can be transferred to the
INTUITY AUDIX system. See the section titled Configure
the Switch Network for a list of documents to use to set up the
network.
Installation Checklist
Follow the steps in the CVM—IMC
Installation Checklist to complete the CVM—IMC installation.
Installation Tasks
This section includes the actual
tasks to complete to install DEFINITY CVM—IMC. Follow these steps
in the order given.
Configure the Switch Network
The switch network must be working
properly using a mode-code integration before connecting the INTUITY
AUDIX system to the CVM—IMC network. Given the complexity of the
configuration and the possible configuration options, any steps for
completing the integration must come from the respective documentation.
These documents include:
- DEFINITY ECS R8.2 Administration
for Network Connectivity, 555-233-504
- DEFINITY ECS R8.2 Administrator's
Guide, 555-233-506
- MERLIN LEGEND and MERLIN
MAGIX Communications System (see the respective Network Reference)
Reserve the Switch Voice
Port for MWI
A CVM—IMC integration uses
mode-code transfers. Since this method is slower than others, the last
extension on each voice port circuit card on the switch must be reserved
for MWI updates by excluding it from the hunt group. Otherwise, MWI
updates must often wait for a port. Reserving one port on each card
allows MWI updates to occur without delay.
Assign only the first five extensions
of each voice port circuit card to a hunt group on the hub switch. If
the last extension is not part of the hunt group, the switch will not
use it to route traffic to the INTUITY.
Note: If a customer uses
less than a full voice port circuit card, skip any unused ports and
use the last port on that card for MWI updates.
For more information about assigning
extensions in hunt groups, see the documentation for your switch listed
in the Configure the Switch Network section.
Install the INTUITY AUDIX
System
If this is a new installation,
follow existing documentation to install the INTUITY AUDIX system.
Use any of these documents that
you find helpful:
Verify Switch Settings on
the INTUITY AUDIX System

must be set correctly on the INTUITY AUDIX system to work with the switch
integration.
To set the Message Waiting Indicators:
- Start at the Administration
main menu and select:
Switch Administration
MWI Administration
Device Assignment
The Device
Assignment page is displayed.
- Enter 1
in the Switch Number field.
- Enter 3
in the Device ID field.
- Click Save.
- Continue with Determine the Active Channels
to Reassign.
Determine the Active Channels
to Reassign
The last active channel on each
voice circuit card must be assigned to a separate group for use by the
message waiting indicator. Use this procedure to determine which channels
to reassign.
To determine the active channels
to reassign:
- Start at the Administration
main menu and select:
Diagnostics
Voice Equipment Diagnostics
The Display
Voice Equipment page is displayed.
- Check the CARD
and PORT column for the number of analog-line voice cards.
The voice port circuit
card numbering starts at zero and increments by one through to five.
For example, if a system has two analog-line voice cards, the first
card's ports would be numbered 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5. The
second card's ports would be numbered 1.0, 1.1, 1.2, 1.3, 1.4, and
1.5.
The last active port
on each card must be reassigned from group 2 to group 3 for use as
the MWI port.
- Record the card,
port and group information in the following MWI Port Old and New Group
Assignments table.

Assign the Last Active Ports
After determining the ports to
reassign, use this procedure to complete the reassignment.
To reassign the last active ports:
The Unassign
Channels from Groups page is displayed.
- In the
Channels field, enter 5 (or the number for the last
active channel on this voice port circuit card).
- In the Groups
field, enter 2.
- Click Unassign.
The system displays
the message:
Channel X deleted from equipment group(s) 2
Press the acknowledge key to continue
X is the last
active channel on the voice port circuit card.
- Click OK
(Acknowledge).
- Click Back.
- On the Voice Equipment page, click Channels to Groups.
The Assign Channels to Groups page is displayed.
- In the Channels field, enter the same
channel number as in Step�3.
- In the Groups
field, enter 3.
- Click Save.
The system displays
the message:
Channel X is assigned
to equipment group 3
Press the acknowledge key to continue
X is the last
active channel on the voice port circuit card.
- Click OK
(Acknowledge).
- If there are
more channels to reassign, go back to Step�2
for the next channel.
- Click Return to Main to return to the Administration main menu.
- Continue with Update
Automated Attendant Routing.
Update Automated Attendant
Routing
Use this procedure if the switch
network includes a MERLIN LEGEND or MERLIN MAGIX. If the network includes
only DEFINITY systems, skip to Set the Dial
Plan.
Normally, automated attendant
routing does not require any modifications from default settings. However,
CVM—IMC requires that the extension length be changed from the
default Merlin Legend length to four digits, so the INTUITY AUDIX auto-attendant
routing table must be updated to include the changed trunk numbering.
To update the auto-attendant routing
table:
- Start at the Administration
main menu and select:
Global Administration
Messaging Administration
The system displays the SSH
User Authentication dialog box. Enter your login, for example, sa or vm,
in the User name field and your password in the Password
field. Click Login. The system then displays the AUDIX
Command Prompt screen.
- At the command
line, enter change auto-attendant-routing routing-table.
The system displays
the Auto-Attendant Routing Table.
- Update the Auto-Attendant
Routing Table to include the MERLIN LEGEND dialing plan and other
system settings.
For more information
about administering the Auto-Attendant Routing Screen see, Setting
Up a Call Routing Table.
- Continue with
Set the Dial Plan.
Set the Dial Plan
Verify that the range of INTUITY
AUDIX extensions is sufficient to include all subscribers on all switches
in the network.
To assign the channels:
- Start at the Administration
main menu and select:
Switch Administration
Dial Plan Translation
The Dial
Plan Translation page is displayed.
- Verify that
the Switch Start Ext. and Switch End Ext. fields
range from zeros to nines for the extension length of the CVM—IMC
network.
For example, if the
INTUITY AUDIX Extension Length is 4, then the range of extensions
would be from 0000 to 9999.
Some customers might
require that specific extension ranges be used instead of one range
that includes all extensions. This method will also work properly,
but it is not necessary for this integration.
|
If the customer requires that specific extension ranges be entered,
the Switch Number must be "1" for every range. Any range with
a switch number other than 1 will not have calls transferred
to it.
|
- Do one of the
following:
- If the range is not
correct, tab to the respective fields and change the entries.
- If the range is correct,
continue with Test the Installation.
Test the Installation
Confirm that the installation
is correct by placing test calls through the network to leave and retrieve
messages.
In general, follow these steps:
- Place a call
from inside the network that goes to voice mail.
- Place a call
from outside the network that goes to voice mail.
- Verify that
the MWI lamp turns on.
- Retrieve the
in-network message.
- Retrieve the
out-of-network message.
- Verify that
the MWI lamp turns off.
- Return to Step�1
and follow the same procedure for each switch in the network.
