The TCB-2 automatically answers
a telephone line on the first ring and disconnects that line
when the calling party hangs up. It is ideal for unattended
situations such as listen lines, IFB feeds, dial-up network,
remote transmitter sites and satellite links. The TCB-2 needs
a momentary open or reversal from the central office to disconnect.
Most but not all CO's provide this signal. An optional dial
tone detect board is available if required. The TCB-2 is powered
by an external AC or DC Supply.

The TCB-1 provides a switched hold connection to a telephone
line so that the telephone set may be hung up during program
feeds. This eliminates the need for special telephone instruments
with push-to-talk handsets or exclusion keys. Use with any modular
phone to send or receive live or taped material. The TCB-1 does
not interfere with normal use of the associated telephone instrument
and does not require batteries or external power.
