Same Here, Excitel by default uses 2 Pair. But they say it can't support more than 75 Mbit.
Anyhow, Ethernet has no future since it has a lot of issues like Packet Loss, Frequent Disconnection (Switch Gets Hanged, needs frequent re-starts), Weather Vulnerability.
Fiber > Ethernet. But, I don't think Fiber will be coming soon in area where Excitel has not even 100 Customers.
