Meaning of parameters in ISDN setup message.

[Joran]

Hi,

Does anyone have information about the meaning of different values in the ISDN setup message from a t3 trace on a OPE?

The OPE is respinding on a call with ISDN Cause No. 100 - Invalid information element contents,
but it is not so easy to resolve what information the OPE is rejecting.

Outgoing call is OK, so I suspect the Vsat operator to send a setup message for inncomming call with information that OXE is rejecting..

See trace below..

This is written in the ETSI Specification

Octet 1=[04] = Bearer Capability
Octet 2=(l=3) = Length
Octet 3=80 = Speech
Octet 4=90 = 64 kbit/s
Octet 5=a3 = Layer 1 G.711 A-law

Octet 1=[18] = Channel identification
Octet 2 =(l=3) = Length
Octet 3= a9 Channel exclusive
Octet 4=83 Channel list follows
Octet 5=8a Channel Nb. 10

Octet 1=[6c] = Calling party number CgN
Octet 2=(l=11) = Length
Octet 3=80 = Number Presentation allowed (8x) / not verified (x0) / Typ of numbering unknown / Numberingplan unknown
Octet 4ff=4773894815=Calling Number

Octet 1=[70] = Called party number CdN
Octet 2=(l=5) = Length
Octet 3=Typ of numbering unknown / Numberingplan unknown
Octet 4ff=6170=Called Number

=> CAUSE (l=3) 81 e4 70 => Called number => What is 6170
