Hi All;

We are doing a configuration to link with another Simens switch via E1, they 
gave us these paramters to be setted, but we are facing  an error at the trunks 
related to Asyn problem, look like something related to synchorinzation.

The simens paramters are:

Line Coding:  HDB3
Country Protocl:  ISUP
Protocol Version: V3
CRC4:  CRC4MF
Interface Companding (like alaw and so on): a-LAW
Impedance: 75 ohm

Interworking Message (like PROGress or what):
Basically support interworking messages as per V3


Actually, I do not know how to configure the ISUP and the V3 on my side? Any 
help?

Also, what is the difference between CRC4MF and CRC4? Any specific thing need 
to be considered?

Regards
Bilal
