NFORMATION
Should terminal equipment or protective circuitry cause harm to the
telephone network, the telephone company shall, where practical, notify the
customer that temporary discontinuance of service may be required.
However, where prior notice is not practicable, the telephone company may
temporarily discontinue service forthwith, if such action is reasonable in the
circumstances. In case of such discontinuance, the telephone company
shall (a) promptly notify the customer of such temporary discontinuance, (b)
afford the customer the opportunity to correct the situation which gave rise
to the temporary discontinuance, and (c) inform the customer of his right to
bring a complaint to the FCC pursuant to the procedures set forth in
Subpart E of the Rules, Part 68.
If the telephone company makes changes in facilities equipment, operation
or procedures which render customer equipment incompatible with the
telephone company facilities, the customer must be given written notice to
allow the customer an opportunity to maintain uninterrupted service
.

The Comrex TCB-1 Telephone Coupler provides a clean,
transparent transformer connection from a telephone line to
external equipment. The coupler connects to the phone line with
modular plugs and program may either be sent or received. The
TCB-1 is designed and FCC registered specifically for broadcast
use and does not require batteries or external power.

NSTALLATION
Note: The telephone company must be informed of the FCC
Registration Number and Ringer Equivalence Number prior
to installation.
The TCB-1 should be connected directly to the telephone line
modular jack and used with a single line modular telephone set.
The coupler may be placed on a desk or mounted on a wall or
other vertical surface using two #6 round head screws spaced
3.9 inches apart to align with the key-hole slots on the bottom of
the coupler. The existing modular cord will connect the telephone
to the coupler. An extension modular cord will be needed to
connect from the wall jack to the coupler.
The TCB-1 is not designed to connect "downstream" of an
electronic PABX system. To connect to a key system, you will
need a device to adapt the 50 pin ribbon jack to an RJ-11C
modular jack. Telephone stores provide various units to interface
with one or more lines on standard key equipment. The TCB-1
may not be used with party lines or coin phones.
The TCB-1 will either send or receive audio, but will not do both
at the same time since it does not provide isolation between send
and receive. The TCB-1 has no amplification or attenuation
capability. This means that a level of approximately -9 dBm
should be used to feed audio into the coupler. The receive level
will be whatever the phone line delivers (usually -20 dBm).
