[Asterisk-Users] Telmex PRI line configuration problem

[Oscar Carriles]

Hi,

Im so confused regarding Telmex specification of my ISDN PRI line.
The following is the line specification from Telmex:
----------------------------------------------------
Phisical interface:g703 
coding: hdb3 
signalling:isdn pri 
clock: recover 
crc4: yes 
framing:pcm30 or cas             
In case you have a Cisco device: 
controller E1 X/X/X 
framing CRC4 (esto depende de como esta armado del otro extremo) 
pri-group timeslots 1-31 

interface SerialX/X:15
no ip address
load-interval 30
no snmp trap link-status
isdn switch-type primary-net5
isdn incoming-voice modem
isdn T310 120000
isdn negotiate-bchan
isdn sending-complete
isdn outgoing-voice info-transfer-capability 3.1kHz-audio
no cdp enable
-----------------------------------------------------

1) Is it possible to have CAS framing with no R2?

Could be my zaptel.conf look like this?

; no "cas=" defined here cause the driver assigns that to MFCR2
span 1,1,0,cas,hdb3,crc4,yellow
bchan=1-15
bchan=17-31
dchan=16

Some help needed
Thanks in advance
