[asterisk-users] ISDN30 Timing Sources (Jon Morgan)

[Jon Morgan]

Thanks for that Russell. Seems the only difference we have is that you have a cable > 133 feet. :-)

I'm baffled as to why we have these issue now.  It's been working fine for years but just started getting all these pops, clicks and calls cutting out recently.

Cheers,

Jon.

>We have a 2 port Digium TE220P card, one span is configured to connect to our ISDN30 provider (British Telecom), the other span connects to our internal PBX.  Here's the zaptel.conf snip:

>span=1,1,0,ccs,hdb3,crc4
>bchan=1-15
>dchan=16
>bchan=17-31
>
>span=2,0,0,ccs,hdb3,crc4
>bchan=32-46
>dchan=47
>bchan=48-62

FWIW, I (also BT ISDN30 on span 1 with a PBX on the second port of a
TE205P) have the following zaptel.conf.

span=1,1,1,ccs,hdb3,crc4
bchan=1-15
dchan=16
bchan=17-31

span=2,0,1,ccs,hdb3,crc4
bchan=32-46
dchan=47
bchan=48-62

I do all my call recording in asterisk so can't comment on that but the
PBX users are not complaining about the quality.
