Network Customer Support
The Network Customer Support Plan identifies the steps to be followed in resolving the
Customer’s concern.
The resolution efforts will follow these levels of contact:
• Level One Contact – Factory Authorized Service Center.
• Level Two Contact – Comtech EF Data Customer Support.
• Level Three Contact – Network Test and Field Support
Procedural Steps
Step Procedure

The Customer raises a concern with the Level One Contact.
The Level One Contact will perform Hardware repairs and Network Operations
troubleshooting in accordance with the Comtech EF Data Service Center
agreement.
If the Level One Contact is unable to resolve the concern, then the Level One
Contact will inform the Level Two Contact of the concern in accordance with the
instructions found within the attached Comtech EF Data Customer Support
Department’s document.
The Level Two Contact will enter the concern into the Comtech EF Data database
and determine whether the concern is a Hardware concern or a Network
Operations concern
The Level Two Contact will interface with the Level One Contact and provide
the appropriate hardware support and enter all correspondence into the Comtech EF
Data database.

If the Level Two Contact determines that the concern is a Network Operations
concern, then the Level Two Contact will inform the Level Three Contact.
The Level Three Contact will interface with the Level One Contact and provide
the appropriate support and enter all correspondence into the Comtech EF Data
database.
If the Level Three Contact determines that there is a Hardware failure then the
Level Three Contact will inform the Level Two Contact. Go to Step 5.

A representation of the equipment installed into the rack, equipment front and
rear panel views, and wiring diagrams also are included.
• If a station has multiple equipment racks, then multiple documents will
be required to record each equipment rack installation (one document
per rack).
For the purpose of this manual, the equipment rack is identified as
‘Equipment Rack Number 1.’
For installation with multiple equipment racks, the rack identification number
shall be incremented.
The Title Box shall be modified to identify the required information, as shown
on the Cover.
