I tested it already.
I configured HDLC encapsulation of FSIP (cisco), and then
I setup similar ways (direct connection between FSIP and E1
interface of F-R switch. (the encapsulation is HDLC).
[R] ----- [F-R clouds] ------- [R]
^hdlc (E1 port) ^hdlc (E1 port)
The PVC is working under above environments.
I want to know how to apply this result into Channelized Interface.
