Telephone Couplers

Overview

Comrex Auto-Answer and Manual Telephone Couplers provide clean, transparent transformer connections from telephone lines to external audio equipment. State of the art circuits and rugged construction assure highest quality and years of reliable service. Both couplers feature modular jacks for quick installation by non-technical personnel. Comrex Telephone Couplers are designed and FCC registered specifically for broadcast use. Program may either be sent or received on both the auto-answer or manual models.

For units that simultaneously send and receive audio, see Comrex Digital Hybrids.


TCB-2 Auto Answer Telephone Coupler

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.

TCB-1 Manual Coupler

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.
