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.
