We don't have a live SS7 link in the office but I do have an Inet
Spectra SS7 simulator/emulator with ISUP. It has been used to debug
other SS7 stacks on commercial SoftSwitch/NIVR platforms with great
success. It can generate calls and inject maintenance
messages/deliberate errors etc. The Spectra supports up to four SS7
signalling links and multiple point codes. With a bit of fiddling the
Spectra can be used remotely but you have to use a DOS based client; I
don't have the Unix version of the remote client application.
For independent verification of the signalling conversations "on the
wire" we also have a GN Nettest MPA (Multi Protocol Analyser) with
ISUP. This device will also spot transmission errors when performing
long duration tests. (There's nothing like an idle SS7 link,
generating lots of FISUs to really find out if a link is stable)
The bad news is the I only have an old single E1 card in our test
system and the brief loan of a more modern dual E1 card (both Digium).
Can these cards be used to run chan_ss7 or do I have to obtain a TE4XX
card? Our model system uses SuSE 9.2, does that present any problems?
No, it should work with any of those cards. SuSE also should work just
fine.
I actually got it up and running on a switch today that Luciano Ramos
from the list let me try. I found a small bug that I had introduced in
the IAM parsing code when I was adding ANSI support, but I fixed it
tonight and calls should work just fine now.
