In our GSM n/w We have two BTS connected to BSC via Satellite Link.These two sites are showing LAP-D congestion and Call Setup is very low. We have no provision of providing an alternate terrestial connection to these sites. Do any parameter has to be changed in BTS or any tweaking required at BSC side.Have any of you observed such a problem ..Help needed!!

You can use any equipment for A-bis optimization ( Available on market).
Cuz it is effective way exately for your situation (few & far away # of BTSs lack of LAPD resources).
You ought to invistigate this solution with your vendor to ascertain the devise compatability.
