Overview
The 200A Module Analog Adjunct Interface is an optional device that can be installed with the Avaya 2420 Digital
Telephone. This module allows you to connect an analog device (such as an answering machine) to the
telephone.
NOTE: Disconnect the 2420 telephone from the wall jack and remove power before removing and/or installing
the 200A module. Refer to the 20A Stand, 200A Module Analog (U.S.) Adjunct Interface, and 201A Module
Recorder Interface Installation and Safety Instructions (555-233-132) for more information.
Requirements
The 200A requires the installation of the 20A Desk Stand. Refer to the 20A Stand, 200A Module Analog (U.S.)
Adjunct Interface, and 201A Module Recorder Interface Installation and Safety Instructions (555-233-132) for
more information.
Switch Settings
The 200A has two channel setting switches that allow you to specify whether an analog device connected to the
200A uses the same line as the 2420 telephone (Channel 1) or separate lines (Channel 2). For more information,
refer to the 20A Stand, 200A Module Analog (U.S.) Adjunct Interface, and 201A Module Recorder Interface
Installation and Safety Instructions (555-233-132).
Troubleshooting
Visual Power Indicators
The 2420 telephone display provides visual indication whether the module has power. To view the power status,
select the Options softkey from the 2420 telephone Home screen, and then select the Self Test feature button.
“-” indicates that the module is not receiving power or is not operating properly. “1” indicates that a single module is
receiving power and is operating properly. “2” indicates that two modules are receiving power and are operating
properly.
Resolving Problems
If the module is not receiving power or you do not receive dial tone, refer to the following information to resolve the
problem.
PROBLEM: MODULE DOES NOT HAVE POWER
1Verify that all cords are securely connected at both ends.
2Verify that the power cord connecting the auxiliary supply to the telephone is an 8-wire cord.
3Verify that the 20A stand is connected to the 2420 telephone.

2
PROBLEM: THE MODULE DOES NOT HAVE DIAL TONE
1Verify that the module has power. (Check the visual indicator on the telephone display.)
2Verify that all cords on the module, the 20A stand, and the auxiliary power supply are securely connected at
both ends.
3Verify that the switches on the module are set correctly. For more information, refer to the 20A Stand, 200A
Module Analog (U.S.) Adjunct Interface, and 201A Module Recorder Interface Installation and Safety
Instructions (555-233-132).
4Check with your system manager to make certain that the 2420 telephone has been administered correctly.
5Connect the affected module with another 2420 telephone that has a working module. If the module being
tested still does not work, it is faulty.
If the module being tested works with the other telephone, try the working module taken from the other
telephone and connect it to the telephone experiencing the problem. If this module does not work, the
telephone is faulty.
PROBLEM: THE 2420 TELEPHONE DOES NOT HAVE DIAL TONE
1Make sure the analog equipment attached to your 2420 telephone is on-hook. The analog equipment
attached to your 2420 telephone may be off-hook because it does not detect the “disconnect” signal sent from
the 200A Module. You must manually turn off (that is, place on-hook) your analog equipment.
2If there is still no dial tone, make sure the handset and line cords at your 2420 telephone are securely
connected at both ends.
3If there is still no dial tone, check with your system manager to verify that your telephone is administered
correctly.
4If the telephone is administered correctly but there is still not dial tone, remove power. Remove the module
and refer to the 20A Stand, 200A Module Analog (U.S.) Adjunct Interface, and 201A Module Recorder
Interface Installation and Safety Instructions (555-233-132). If the 2420 telephone, without the module, has
dial tone, connect the module to another telephone.
a. If the module works in the new telephone, the 2420 telephone to which the module was originally
connected is faulty.
b. If the new 2420 telephone, after the module has been connected, does not work, the module is faulty.
5If the original 2420 telephone, without the module, still does not work, find a working 2420 telephone. Unplug
this telephone from its modular wall jack. Plug your 2420 telephone into that jack and verify that it gets dial
tone.
6If the original 2420 telephone still does not work, plug the working 2420 telephone into your modular wall jack.
If the working 2420 telephone has dial tone, your own telephone is faulty. See your system manager.

Problems Related to External Speakerphones
The following problems may occur with some external speakerphones connected to the 200A Module. These
problems may occur with other equipment as well.
PROBLEM: YOU CANNOT MAKE/ANSWER CALLS AT YOUR 2420 TELEPHONE
The analog equipment attached to your 2420 telephone may be off-hook because it does not detect the
“disconnect” signal sent from the 200A Module. You must manually turn off (that is, place on-hook) your analog
equipment.
PROBLEM: ANALOG EQUIPMENT DOES NOT GO ON-HOOK WHEN YOU LIFT TELEPHONE HANDSET
The analog equipment attached to your 2420 telephone may not go on-hook automatically when you lift the 2420
telephone handset for two reasons. First, make sure that the switch settings on the 200A Module are correct.
Remove power and refer to the 20A Stand, 200A Module Analog (U.S.) Adjunct Interface, and 201A Module
Recorder Interface Installation and Safety Instructions (555-233-132). If the settings are correct, the analog
equipment does not detect the “disconnect” signal sent from the 200A Module. You must manually turn off (that is,
place on-hook) your analog equipment.
PROBLEM: ANALOG EQUIPMENT DOES NOT GO ON-HOOK WHEN THE FAR END DISCONNECTS
The analog equipment attached to your 2420 telephone may not go on-hook automatically when the far end of a
call disconnects because the equipment does not detect the “disconnect” signal sent from the 200A Module. You
must manually turn off (that is, place on-hook) your analog equipment.
