I have just had T1 installed and paradynes are the CSU/DSU from ISP. Upon connecting V35 - serial DTE cables and configuring Frame Relay Or PPP i get one router coming up with serial up / line protocol (down). But with one of teh routers it says Serial up / line protocol down (looped).
What do you think is the problem and how can i get is solved. I called ISP and they checked their connections and it is not looped on their end.
