LIT AEI MODEL PRODUCT DESCRIPTION MOUNTING CIRCUITS
CALL 3401 BRIDGE LIFTER The Bridge Lifter assembly is a distributing frame mounted device available with fifty (50) saturable inductors, in 25 circuits, mounted directly on the terminal field. Bridge Lifters are normally used on loaded loops of any length and on non-loaded loops over 6000' / 1828m. Applications include bridging party lines, off premise extensions, secretarial services, central office cutovers, and PBX moves. 211AL-8" BLK 25 pos.
CALL 3402A BRIDGE LIFTER The Bridge Lifter assembly is a distributing frame mounted device available with fifty (50) saturable inductors, in 50 circuits, mounted directly on the terminal field. Bridge Lifters are normally used on loaded loops of any length and on non-loaded loops over 6000' / 1828m. Applications include bridging party lines, off premise extensions, secretarial services, central office cutovers, and PBX moves. 211AL-8" BLK 50 pos.
CALL 3407 BRIDGE LIFTER The Bridge Lifter assembly is a distributing frame mounted device available with thirty-two (32) circuits mounted directly on the terminal field of an 89 type block. Bridge Lifters are normally used on loaded loops of any length and on non-loaded loops over 6000' / 1828m. Applications include bridging party lines, off premise extensions, secretarial services, central office cutovers, and PBX moves. 89 BLK 32 pos.
CALL 4011 4WIRE 6WAY 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. 211AL-8" BLK X pos.
CALL 4012 4WIRE 6WAY 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. TYPE-10 CARD X pos.
