Installing DEFINITY Centralized Voice Mail— Interswitch Mode Code

Purpose

The purpose of this section is to provide basic information about DEFINITY� Centralized Voice Mail—Interswitch Mode Code (CVM—IMC), installation instructions, and administration instructions for integrating an Intuity AUDIX system into the network.

Introduction

This section includes a description of the feature, requirements for the Intuity AUDIX installation, and requirements of the feature.

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 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

You can network to an Intuity AUDIX system.

Requirements

The CVM—IMC integration has these requirements:

• The system operates only with a DEFINITY ECS Release 8.2, ProLogix R3, or DEFINITY BCS Issue 6 as the hub or as endpoints. 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 switch network requires ISDN-PRI trunks with D-Channel between switches.
• 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 must be a MAP/5P.
• On the Intuity AUDIX system, the last active port on each voice 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 integrations 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 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:

• System Installation Checklists
• Intuity Messaging Solutions Getting Connected (585-313-703)

• If DEFINITY MODE CODE is displayed, continue with Set the MWI Indicators.
• If another switch integration is displayed, contact the remote support center.

The existing integration must be unloaded and the SWINset Serial-Inband Switch Integration must be loaded. After this work is completed, continue with Set the MWI Indicators.

Set the MWI Indicators

The message waiting indicators must be set correctly on the Intuity AUDIX system to work with the switch integration.

To set the MWI indicators:

1. Start at the Avaya Intuity Main Menu and select:

Switch Interface Administration
	Call Data Interface Administration
		MWI Administration
			Device Assignment

The system displays the Device Assignment Screen.

2. Enter 1 in the Switch Number field.
3. Enter 3 in the Device ID field.
4. Press F3 (Save).
5. Press F6 (Cancel) twice.
6. 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:

1. Start at the Ayaya Intuity Main Menu and select:

Voice System Administration
	Voice Equipment

The system displays the Display Voice Equipment Screen.

2. Check the CD.PT column for the number of voice port circuit cards.

The voice port circuit card numbering starts at zero and increments by one through to five. For example, if a system has two voice port circuit 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.

3. Record the card, port and group information in the MWI Port Old and New Group Assignments table.


 


Table: MWI Port Old and New Group Assignments

Card	Last Active Port	Old Group	New Group
1			3
2			3
3			3

4. Continue with Assign the Last Active Ports.

Assign the Last Active Ports

After determining the ports to reassign, use this procedure to complete the reassignment.

To reassign the last active ports:

1. On the Display Voice Equipment Screen, press F8 (Actions) and select:

Unassign
	Channels from Groups

The system displays the Unassign Channels from Groups Screen.

2. Select the group to change from the MWI Port Old and New Group Assignments table.
3. In the Channels field, enter 5 (or the number for the last active channel on this voice port circuit card).
4. In the Groups field, enter 2.
5. Press F3 (Save).

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.

6. Press F1 (Acknowledge).
7. Press F6 (Cancel) twice.
8. From the Actions menu, select:

Assign/Change
	Channels to Groups

9. In the Channels field, enter the same channel number as in Step�3.
10. In the Groups field, enter 3.
11. Press F3 (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.

12. Press F1 (Acknowledge).
13. Press F6 (Cancel) three times.
14. Verify that the last active channel is changed to 3.
15. Determine the next step:
• If there are more channels to reassign, go back to Step�2 for the next channel.
• If there are no more channels to reassign, continue with Step�16.
16. Press F6 (Cancel) twice to return to the Avaya Intuity Main Menu.
17. 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:

1. Start at the Ayaya Intuity Main Menu and select:

AUDIX Administration

2. At the command line, enter change auto-attendant-routing routing-table.

The system displays the Auto-Attendant Routing Table.

3. 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 Intuity Messaging Solutions Release 5 Documentation, Setting Up a Call Routing Table.

4. 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:

1. Start at the Ayaya Intuity Main Menu and select:

Switch Interface Administration
	Call Data Interface Administration
		System Translation Administration
			Dial Plan Administration

The system displays the Dial Plan Administration Screen.

2. 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.

3. 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:

1. Place a call from inside the network that goes to voice mail.
2. Place a call from outside the network that goes to voice mail.
3. Verify that the MWI lamp turns on.
4. Retrieve the in-network message.
5. Retrieve the out-of-network message.
6. Verify that the MWI lamp turns off.
7. Return to Step�1 and follow the same procedure for each switch in the network.

Troubleshooting

If testing shows that some aspect of the system isn't working correctly, use the Possible Trouble Areas table to find possible solutions.

 

Table: Possible Trouble Areas

Problem	Check if:	Action
Calls to station on hub switch do not cover to voice mail.	Station has coverage path set up to voice mail.	Add coverage path.
	Station has mailbox on Intuity AUDIX system.	Add mailbox.
	Mode codes on DEFINITY hub match the Intuity AUDIX system.	Make codes on both switch hub and Intuity AUDIX match.
	Mode codes are being received on the Intuity AUDIX system.	Change ports on the hub from "2500" to "VMI."
Calls to remote system do not cover to correct mailbox.	ISDN-PRI trunk is set to "private."	Set trunk to "private."
	Signaling group and trunk group between remote and hub are in service and set to subscriber.	On the DS1 form on the switch hub, set the Interface field to "network." In the same field on the endpoint, set the field to "user."
	Remote site has correct Remote VMS Hunt group.	Add correct hunt group.
MWI is not being updated for stations on the hub switch.	Messages are still in mailbox.	Clear messages and call back to leave another message. Confirm that the MWI is updated properly. Check the activity log against the extension to see that the proper mode codes are being sent.
	LWC store and LWC cancel feature access codes match on the Intuity AUDIX.	Make the mode codes match. Check the mode codes on the switch and on the Intuity AUDIX. If necessary, change the entries on the Message Waiting Parameters screen on the Intuity AUDIX.
	Intuity AUDIX has an analog voice port that is assigned to MWI updates.	Make the MWI port a dedicated port. See Determine the Active Channels to Reassign.
	MWI dedicated port is in the hunt group.	Remove the MWI port from the hunt group on the switch. See Assign the Last Active Ports.
	MWI access codes are being sent from the Intuity AUDIX.	Check the Switch Integration Log for whether the appropriate codes are being sent.
When the system is under load, some calls to Intuity AUDIX are un-integrated.	Switch is getting data to Intuity AUDIX before the call times out.	Contact the remote support center.
	Mode codes are not defined properly.	Reselect the switch and country. Reselecting the switch and country clears any custom settings from the switch integration and requires that they be re-entered.
