I have some apartments blocks, with about 1km of cooper cable (26 pairs, section 0.6mm2, and shielded...but I think that this shield is not connected to anyplace).
I decided install Cisco 2950 LRE (IOS 12.1(22)EA1), and Cisco 575 for clients, without use voice port, because we use ToIP, and then without splitters, only for data transfer.
I have four 2950LRE, and I cant connect more than one port for each switch. I tried all sequences, now is global LRE-SEC-COMPLETE-REACH for "scan" all profiles.
I have seen some parameters, for connected and no connected ports, but I dont understand how is possible to have an SNR 37, and in the adjacent apartment SNR 0.. ( ground power ?, third pairs cable in the wall to CPE port - I am using 2 pairs cable?, insufficient power for all ports from switch ?...
Thanks in advance,
