The intercom does not work
OR
The telephone does not indi-
cate the status of the other
EPIC phones in the system
OR
There is a delay in getting dial
tone.
There is crosstalk or other
interference on the line.
The problem may be with your installation:
Make sure that the telephone lines are properly installed
(See page 9).
The problem may be with one telephone:
Disconnect one telephone at a time to determine if a partic-
ular phone is causing the problem.
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
an RF line filter, which will be sent to you free of charge.
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.
The most common cause of crosstalk is failure to use the
supplied line cords. Be sure to use the line cords that came
with your TMC telephone. If the supplied line cords are too
short, you may purchase 25’ twisted-pair line cords from
TMC (See page v).
