[asterisk-ss7] Link Not Aligned

Tue Dec 15 14:18:30 CST 2009

Hi Guys,

This is the first time , I am posting , but have been reading the list
quietly for a while.

I have a Sangoma A102  , connecting to a Siemens D900 Switch , I cannot get
the link to align at all, The far end switch is  Siemens GSM [ SR 13 ]
switch  , config from the switch side is NCRC, NAT0 , HDB3 , NO Multiframe ,
BCR

[root at in-tickets libss7]# ./ss7linktest 16 itu 2259 2256

2 . AFT-A102-SH : SLOT=14 : BUS=0 : IRQ=58 : CPU=A : PORT=2 : HWEC=64 : V=33

Card Cnt: A101-2=1

I am using the following version of the software

1. Dahdi $Revision: 7539 $, $Date: 2009-11-09 20:32:45 +0100 (Mon, 09 Nov
2009) $
2. LibSS7 - trunk
3. Asterisk - 1.6.2
4. Centos 5.3
5. 2.6.18-128 Kernel

Everything compiles fine and i am able to load dahdi , but the SS7 link is
never aligned and the status is always down
