1. make sure the clocking problem. Comstream should provide the clock
2. make sure you are using the correct type of cable (DTE/DCE type) from
Cisco serial to Comstream port
3. try to loop back comstream (local Loop back), you should find Line
protocol (looped)
4. check your link quality, do a BER Test (for 24 hours) and see the result.
It should be more than 10^ -7
5. your link quality can also be checked by IOS command, sh int s0, check
that your incoming packet errors less than 10% total incoming packet. check
also : how many carrier (DCD) transisison has been occured. execute clear
counter, then, see the show int s0 command for an hour (or less).
6. You seem to have layer 1 problem...

Subject: cisco 2611 and Vsat
Dear all,
Would be grateful if anybody can help with a problem I am facing.
We are using a Cisco 2611 with 1 wic1T (DB-60) and a 4A/S network module
containing 4 sync async ports. The remote router is 1601 with 1 WIC.
The serial port is connected to a SCPC (Single Carrier per Channel)
satellite modem (Radyne Comstream 2041). The problem we face is that
althought both the serial port and line protocol of the port shows up, we
are unable to ping our local Wan port or the remote Wan port. We are certain
that the router components inolved (WIC cards , cables etc) are funtioning
noramlly as we have swapped and tested it on another link.
Also another thing of interest is that when we change the encapsulation
method from the default HDLC to PPP on just one side of the link (either of
the sides), the line protocol goes down (as it should normally). However
even when both the sites are made PPP the line protocol remains down.
I am pretty puzzled with this behaviour. I mean if you line protocol is up
(with out your line being in a looped condition) then things should work
normally.
If any body can give some inputs it is much appreciated.
The congif on the router is given below
