1. how many E1 in every multilink i can have and how many multilinks
MLPPP logically aggregates up to eight (8) E1/T1 so you can have up to 8.
2. can i connect it to cisco or not..
Yes, there were some specific commands that needed to be done, like turn off MLPPP fragmentation on both sides, and an MTU bug which affects only OSPF, but that's it. It might not, in your case....
