Hi Alejendro

Have you managed to find out the solution to your problem!! Im facing the
same problem. The same link connects on another digium card running in
parallel with exactly the same configuration.

Please share with me if you have a clue as I want to try sangoma..i'm
using A104DE instead

Kind regards
Sam

Hi,



I have problems, as linkset shows as DOWN all the time with the following
scenario:



-Dell server with Sangoma A102 (2 E1/T1 Card)

-Ubuntu Server 8.10

-Dahdi Linux 2.1.0.4

-libss7 1.0.2

-wanpipe 3.4.1

-Asterisk 1.6.1.0

#Sangoma A102 port 2 [slot:2 bus:10 span:2] <wanpipe2>

As I don?t have an SS7 equipment/link to test, I decided to make a crossover
cable (1<-->4, 2<-->5) and plugged port 1 to port 2 on the same card.

Everything seems to come up correctly, but when I do: ?ss7 show linkset 1?
it shows as down



*CLI> ss7 show linkset 1

SS7 linkset 1 status: Down



Even if links on the card, and dahdi status seems ok:



*CLI> dahdi show status

Description                              Alarms  IRQ    bpviol CRC4   Fra
Codi Options  LBO

wanpipe1 card 0                          OK      0      0      0      CCS
HDB3 YEL      0 db (CSU)/0-133 feet (DSX-1)

wanpipe2 card 1                          OK      0      0      0      CCS
HDB3 YEL      0 db (CSU)/0-133 feet (DSX-1)



When using ss7linktest I get this:



# /usr/src/libss7-1.0.2/ss7linktest 16 itu 1234 4321

Starting link 1

Link state change: IDLE -> NOTALIGNED

Len = 4 [ ff ff 01 00 ]

FSN: 127 FIB 1

BSN: 127 BIB 1

>[0] LSSU SIO



I have no experience at all using ss7 (I only have used ISDN PRI), so please
be patient if you find I?m doing something totally wrong hehehe.



Thanks in advance for your help!

Alejandro Mej?a
