Hi

Hi dicko

i have small confusion when installing R4T1 rhino card

on the trixbox 2.6 when i installed R4T1 card on the zaptel.conf i have the following parameters.

#SPAN 1 in Rhino R4T1 for Etisalat ISDN PRI
#span=1,0,0,ccs,hdb3
span=1,1,0,ccs,hdb3 # As span port is directly connected to Telco to accept timing source from them
bchan=1-15,17-31
dchan=16

where do i place this parameters when i install elastix 1.6 as when i checked the dahdi-channel.conf it was auto generated

; Span 2: R4T1/0/1 "R4T1 (PCI) Card 0 Span 1"
group=0,12
context=from-pstn
switchtype = euroisdn
signalling = pri_cpe
channel => 17-31,33-47
context = default
group = 63

is it necessary for the following statement "span=1,1,0,ccs,hdb3" to be on the dahdi-channel.conf

when i checked some forum they say the above line has to be put on /etc/dahdi/system.conf

pls help


pls advice

When zaptel was zaptel the hardware and the connected trunks were defined/described in /etc/zaptel.conf and the channels on the hardware in /etc/asterisk/zapata.conf (and it's inclusions)

When zaptel turned into dahdi, the same division is made, the hardware and trunks in /etc/dahdi/system.conf and the channels in /etc/asterisk/chan_dahdi.conf (and it's inclusions)

The confusion many have is that dahdi is a kernel level driver that is loaded on system startup and presents the dahdi/zaptel hardware as "system devices" it has nothing to do with asterisk per-se and the devices can indeed be used by FreeSwitch etc.

How that hardware is partitioned, conditioned and used by Asterisk is in the standard /etc/asterisk/diurectory conf files.

My guess is that Elastix setup already has done this for you in

/etc/dahdi/system.conf

Just check it, if you have extraordinary spans as to timing source or build-out here is were to change it just like in zapata.conf.
