Installing the Meridian Mail to PBX interface 11-11

Establishing the AML connection between Meridian Mail and the Meridian 1

Standard 1.0 Modular Option EC Installation and Maintenance Guide November 1999

Establishing the AML connection between Meridian Mail and

the Meridian 1

Introduction

When Meridian Mail handles a telephone call, it receives

information about the call from the Meridian 1. That is,

Meridian Mail must know the number that was dialed, whether

the call was internal or external, and so on. The switch

(Meridian 1) passes all this information to Meridian Mail

through the data link.

In the same manner, Meridian Mail sends information back to

the switch through the same link. For example, if the caller thru-

dials to another number, Meridian Mail passes this number back

to the switch to transfer the call.

This data link is the Applications Module Link (AML), known

also as the Integrated Services Digital Network/Application

(ISDN/AP) link, or the Command and Status Link (CSL).

Without the AML, Meridian Mail has insufficient information

to process the call correctly.

Hardware

requirements

To establish the AML data link, you must install the following

hardware:

• MSDL card (NT6D80AA) or ESDI card (QPC513, version

H or later), which occupies a slot in a common equipment

module of the Meridian 1

• cabling (NTND91AB) from the MSDL or ESDI card to the

Meridian Mail backplane

You must also program the link in the Meridian 1 software by

modifying the configuration record in LD 17 (described in

Chapter 13, “Starting up and configuring Meridian Mail”).

Note: The MSDL and ESDI cards are both I/O cards that can

serve as the interface between the Meridian 1 and Meridian

Mail. However, you can only use the MSDL card with X11

software Release 18 or later; you can use the ESDI card with

any release of X11 software.

Software

requirements

You must select three values to program the AML: a device

number (DNUM), AMLs, and value-added server identifiers
