I will be linking a remote office to the head office. There is an old two pair telephone wire from HO to remote office. I've read the data sheets regarding the LRE, but I am still confused on how to use it. Could you please answer my concerns? 1. Do I need a LRE switch on the HO? 2. If there are only 4 wires, how could I connect the wires to the LRE switch? 3. If there are 80 users in the remote side, do you reccommend using the LRE technology?
Thanks.
