Public switches (AXE10) not capable of handling sustained call setup bursts on E100P
Hi,
I'm running a simple test from asterisk towards a
public telco switch (AXE10) over E100P.
Here is the test case:
1) 30 calls are setup simultainously, 20 sec ringing
time.
2) no calls answers (just calling a vacant public tax
office :=)
3) Each channel will continue on its own with the same

Useful information - UK exchanges and SystemX/SystemY and how ISDN works!

contact BT to see if the D channel going up and down is a problem.
It turns out that this is perfectly normal and the ETSI ISDN specification
doesn't state that the D channel has to be permanently up or down.
Apparently, there are two kinds of exchanges:
System Y exchange (AXE10) - Thorn/Ericsson
Layer 2 (D channel) drops every 50 seconds
System X exchange - Marconi
Layer two stays active permanently
So, if you see this warning, you know what the problem is (or rather that
there isn't a problem!).
Cheers,
Nick.
