Dear Sir,
It's the first time we use SS7 signaling, we have sangoma A104 card and we
want to use it for our new SS7 connection with telco.
Please I need help how I can apply libss7 parameters with one that telco
sent it as below:
SS7/C7 PARAMETERS
Link 1 System #1
Span # = 1st E1
Time Slot = 1
Originating Point Code = 1081 (MSC1) NI=3
Destination Point Code = 1056 (Audio telecom server) NI=3
SLC = 0
Link Type = F
Note: Point codes above are in decimal format.
****************************************************************************
***
ISUP SPECIFICATIONS --> ITU
****************************************************************************
***
ISUP PARAMETERS: Enter your CIC mapping into the following table or provide
additional sheets with this information.
CIC = 2-31
Span # = 1st E1
Timeslot = 2-31
CIC = 33-63
Span # = 2 nd E1
Timeslot = 1-31
CIC = 65-95
Span # = 3rd E1
Timeslot = 1-31
CIC = 97-127
Span # = 4th E1
Timeslot = 1-31
****************************************************************************
****
E1 configuration:
FRAMING = No Multi frame structure (E1 only)
LINE CODE = HDB3
SS7 = ITU SS7
SS7 link type = F link
And our libss7 configuration:
signaling=ss7 ;this is ss7 signaling
ss7type=itu ;using the ITU variant
ss7_called_nai=dynamic ;NAI for outgoing calls
ss7_calling_nai=dynamic ;NAI for incoming calls
ss7_internationalprefix=00 ;international prefix value for
incoming calls
ss7_nationalprefix=0 ;national prefix value for
incoming calls
ss7_subscriberprefix= ;subscriber prefix value for
incoming calls
ss7_unknownprefix= ;unknown prefix value for incoming
calls
ss7_explictacm=yes ;ACM is send as soon as call enters
the dial plan...may not accepted yet though
linkset= ;arbitrary name for this set
of channels
pointcode= ;the point code for this
system...aka SPC
adjpointcode= ;the point code for the system
that we are signaling to... aka APC
defaultdpc= ;the point code for the system
that the CICs will be negotiated with...aka DPC
networkindicator=international ;NI value for MTP3
cicbeginswith= ;the starting value of the CICs
channel= ;the channels that are CICs
sigchan= ;the signaling channel
