[asterisk-ss7] SS7 with 2 link on same linkset

Fri Mar 12 12:44:02 CST 2021

Hi,

I have a 16 port card (Sangoma), all E1 works good, but when I tried to
enable a second link it show a lot of notice with

SS7 got event: HDLC Abort(6) on span 1/1

As far as I know this is because hardware (cable, conecctions, etc) on
wanpipemin signal is Rx Level        : > -2.5db.

Other problem is irq this was solve with chunk_size=80 en dahdi when
compiled (see below).

I already tried:

I compile wanrouter and dahdi with chunk size 80 to solve IRQ problem, this
works because same problem when enabling more than 9 ports, after change to
chunk_size=80 problem was solve, I can enable 16 ports, but just with 1
link. 

using slc=0 and slc=1 on chan_dahdi with no results.

IRQBalance enable and disable, and manual selection of SMP_afinity doesn't
change anything.

On chan_dahdi I tried using span number 1 for all as the config below, and
span 1 to 16 with no change, clock sync on channel 1 of 1 port to span 1,1.

Ej:

span=1,1,0,ccs,hdb3,crc4 on ports with link.

span=1,0,0,ccs,hdb3,crc4 on ports with just cic channels.

Tried with

span=1,1,0,ccs,hdb3,crc4 port with link

span=2,0,0,ccs,hdb3,crc4

.

.

.

span=9,1,0,ccs,hdb3,crc4 port with link

.

.

.

span=16,0,0,ccs,hdb3,crc4

and same results.

Here is my wanpipeX.conf

Changing CRC to NCRC have no efect, HWEC YES or NO works either way.
TE_CLOCK should be normal even on the port with link, as far as I know.

HW_DTMF should be allways disable. And D_CHAN=0

and asterisk/chan_dahdi.conf

Tried with slc=0 below sigchan=1 and slc=1 below sigchan=249. Now is
commented because this is the only way I can have all port UP and 1 link UP.
