Dear all,
I have a pbx and cisco 2821 with vwic.
i want to OPX on my router.
So on my pbx cas is configured with 30 specific number. on router side i have configured 30 seperate DS0 channel to achive 30 dedicated voice-port.
i have als0 30 FXS port on my router.
how can bind each fxs port into specific timeslot?
any idea?

Each fxs had a different plar string for a different timeslot. Any fxs is ok for that.

Hi, you've asked this question already, which signaling type do your PBX uses ?
Eg, if E1 R2, is not necessary to assign each port to a timeslot.

the signalling between pbx and router is fxo-loop-start.
i have provided the connection between pbx phone extension into fxs ports.
but the problem is when you dial-out from fxo phone into pbx every time one number is appeared on pbx phone extension.
it seems some kind of round robin between dso timeslot..but i need one fxs phone uses just one and specific ds0 timeslot for dial-out.
any way thank you for you follow up my friend.

Ok. Remove the 'cas-group' under controller. Configure instead 30 times, cas-group number from 1 to 31 with the correct timeslot - remember you have to skip 16.
Configure 30 dial-peers, one for each of the new 30 voice-ports that are consequently created, with destinaion-patter like C01 ... C31.
Under the voice-ports for fxs, configure "connection trunk Cxx" with xx being number for the corresponding timeslot.
This way, as soon you lift phone, you will have dial-tone from PBX.

HI dear bevilacqua ;
according to your idea I have to small mistake.
I have to define "Connection PLAR ####" for each logical voice port "voice-port 0/3/0:1"
to make pbx extention call into fxs phones..
---here my config------
controller e1 0/3/0
ds0-group 1 timeslot 1 type fxo-loop-start
ds0-group 1 timeslot 1 type fx0-loop-start
.
.
voce-port 0/3/0:1
connection plar 40001
voice-port0/3/0:2
connection plar 40002
.
voice-port 0/1/0
description fxs port
voice-port 0/1/1
description fxs port
!
!
dial-peer voice 40001 pots
port 0/1/0
destination-pattern 400001
!
dial-peer voice 40002 pots
port 0/1/1
!
!
dial-peer voice 41000 pots
port 0/3/0:1
forward-digit all
dial-peer voice 41001 pots
port 0/3/0:2
forward-digit all
.
.
note:
4100X are my pbx extension
behinde my pbx I have about 100 extensions
how can i dial all of them from my fxs phones??
note2:
calls from pbx to fxs are woking fine.

Hi,
under DP 41000 ... 41030 you need destination-pattern. I suggest to use Cxx, but you can use anything that is configured as connection plar under fxs port.
05-08-2008 03:01 AM
please tell me how PBX dial tone will provided?
and what is your meaning with CXX?
05-08-2008 03:20 AM
Once plar completes, fxo goes off hook and you have dialtone. Cxx are just numbers, you can use others.
05-08-2008 03:51 AM
You mean that I should provide "connection plar XXXX" under my FXS voice-port?
that XXXX mentions to PBX phone extension number?
then how it understand to select proper dso timeslot..(To prevent worng caller id on pbx extension)
thank you again.

teh other poitn is that is FXS-DID needed for this isuue or normal FXS can handel it?
05-08-2008 04:00 AM
Each fxs had a different plar string for a different timeslot. Any fxs is ok for that.
