- I was wondering what advantages there are for 4 wire vs 2 wire
- leased lines. It seems as though more modem manufacturers are
- offering a 2 wire option (if they have leased line capability)
- than 4 wire. Is that because of cost considerations?
-
- It is my understanding that all telephone connections between
- telco central offices are 4 wire, so from that standpoint,
- a 4 wire option would seem the best (less echo problems, etc).
-
- Any comments? (sorry if this is a FAQ).
