4011 - 4 WIRE 6 WAY ACTIVE BRIDGE

The Bridge is used in voice frequency conference networks and allows a transmitting station to communicate simultaneously with all the other receiving stations connected to the bridge. Model 4011 is an active bridge providing 4-wire conferencing, receiving attenuation and transmit. Gain and attenuation on individual ports can be easily changed to provide equal level conferencing. The bridge is mounted on a 211AL-8" terminal block. Unit allows full jack access to XMT and RCV legs for testing facilities and bridge. K-Pads are used for REC attenuation and XMT gain adjustment.

4012 - 4 WIRE 6 WAY CONFERENCE BRIDGE

A VF or data signal received at any receive port is transmitted to all other transmit ports (minus the assoc. port) providing leg to leg communication. The Active Conference Bridge has front panel mounted transmit and receive gain adjustments and are provided for each bridge port. Proper adjustment allows for signals on the bridge to be transmitted and recieved at the same level. The unit is mounted on a 400 type card mounting. 0dB loss bridge, with adjustable gain of -10dB to +22dB. -48V power. Used with voice or data up to 9.6 kbps.
