The problem may be caused by interference:

 

 

Disconnect all possible sources of interference one at a time

 

to determine if one of these is causing the problem.

 

Possible sources are such things as other phones, fax

 

machines, modems, or such things as radios or computers

 

in extremely close proximity. Note: All non-TMC intercom

 

telephones are incompatible with this system, and MUST be

 

removed.

 

The problem could be caused by outside interference:

 

Disconnect Line 1 from dial tone at the network interface. If

 

this solves the problem, then the interference is coming from

 

outside over Line 1. If this is the case, call TMC to request

The problem may be caused by DSL microfilters. Note

 

that DSL microfilters are not compatible with this system. All

 

DSL microfilters installed behind these telephones MUST be

 

removed in order for the phones to operate properly. If you

 

have DSL service, please contact your DSL provider for an

 

alternative method of connecting your DSL without the

 

microfilters.
