[asterisk-users] TELUS British Columbia PRI Settings

[Jeremy.Hellstrom at synovate.com]

I'm not surprised both the conf file and myself are confused.

 

I've pared things down in chan_dahdi.conf to ...

_________________________________________

 [channels]

spanmap => 1,1,0,esf,b8zs

#include dahdi-channels.conf

switchtype => national

signalling => pri_cpe

context => default

_____________________________

As I read the instructions for chan_dahdi, the spanmap -> span = 1,
timing = from PSTN, LBO = 0, framing = esf and coding = b8zs

 

In the header of dahdi-channels.conf it specifies that it is intended to
be included in chan_dahdi and I have noticed that if I remove that line
then I only generate a pseudo channel and no PRI channels.

; Span 1: WCT1/0 "Wildcard TE121 Card 0" (MASTER) B8ZS/ESF ClockSource 

group=0,11

context=from-pstn

switchtype=national

signalling = pri_cpe

channel => 1-12

group = 63

I still end up with messages telling me that a dchannel cannot be found.
Any other suggestions?

 

Thanks, Jeremy

Oh, and that isn't how a spanmap looks either. It looks like you have
mixed some stuff from system.conf and chan_dahdi.conf here. My guess is
your system.conf is configured at least mostly right, and that is why
everything goes green.

If you're only using one span, is there a reason you are using
trunkgroups? I believe those only get used for NFAS and GR-303

Do you have anything defined in this file? Since it comes at the top,
any changes you make below it won't affect anything defined in that
file.

I didn't think bchannel and dchannel were valid for chan_dahdi.conf.
Don't those only exist in system.conf?

I believe you only declare 'channel' for the b-channels in
chan_dahdi.conf.
