This appendix describes the procedures to be used in performing acceptance testing of ADTRAN’s Total 
Access MX2800 M13 Multiplexer. It is assumed that the MX2800 has already been installed, powered-up, 
equipped and cabled to the DSX-1 and DSX-3 or connecting equipment according to the specifications 
described in 

 and local operating company procedures. 

The MX2800 is an M13 multiplexer used to consolidate 28 DS1 circuits on to a DS3. The unit can be 
equipped in various ways. In general, this section addresses the following areas:

• Verifying the options installed on the unit

• Configuring the unit for test

• Testing all DS1 and DS3 circuits to make sure that each circuit passes error free data

• Verifying that alarms are generated and passed to external alarm systems

• Testing the system power supply and controller card redundancy

• Restoring the unit to the desired configuration

• Configuring the unit for customer traffic

• Completing the Acceptance Test Procedures (ATP) Checklist

The installed configuration determines the level of redundancy the unit supports. There may be one or two 
Power Supply Units (PSUs) and Controller Card Units (CCUs) present. A single PSU and CCU are 
required for operation without redundancy. Equipping the shelf with two of each provides full redundancy. 
The PSUs are the smaller modules on the left side. The CCUs are the larger modules toward the center and 
right of the shelf. Visually note which cards are installed in the chassis under test.
