ELU 26 and TLU 76 1

[pikall]

What's the difference between ELU 26 and TLU 76? Both are for Bri connections, but I would like to know what type of equipment can i connect to them.

Thanks

Hi
TLU76 is a digital trunkline for 2Mbit Common Channel signalling (30B+D). The board can be adapted for "no-signal" sending upon major equipment failure (MEF). Furthermore the board can be adapted for earthing the screen in the coaxial cable (for both receive and transmit).

ELU26 is a digital extension line card with four ISDN S-interfaces. Each S-interface has two wires for transmission and two wires for reception of signals.

The board is equipped with four PCB current limiting devices per 4-wire line. If the PCB current limiting device blows, it shall be replaced with a fuse.

Hi, thanks for your answer.

A last doubt, what about the TLU79? is it for bri connections.

Regards and thanks again
