Please let me know how to upgrate 4 e1 channel to 8 e1 channel ?
please suggest . i have asked for internal configuration modification.
If you’re talking about bearer channels, just edit the DAHDI system.conf and Asterisk chan_dahdi.conf configuration files.
If you’re speaking about the actual layer 1 links, you can’t make a 4-port E1 card terminate 8 E1s; you’d need an 8-port E1 card for that.
I am talking about bearar channel. thx for your suggestion malcolmd !!
When i am changing Dahdi system.conf . it is not working !! getting error. chan_dahdi.conf file shows no issue . **
is it possible manually configure /etc/dahdi/system.conf or where need to configure manually? After that need to recompile asterisk or will it work just after restart asterisk and dahdi. please help.
My working procedure are below:
1.Shutdown server.
2.Change e1 card HW ( 4 e1 to 8e1).
3.Startup server.
4.Modify >> /etc/dahdi/system.conf file for 8 e1 channel.
5.Modify >>/etc/asterisk/chan_dahdi.conf file for 8 e1 channel.
6.execute command : # Ispci -nn | grep d161
//Output: 04:08.0 communication controller [0780]:Digium,Inc,Device[d161:] (rev 02).
**7.Execute command:#modprobe wct4xxp.
//No output.
8.Execute command: #dahdi_cfg -vv
// Shows channels reserved.
9.Restarted Dahdi // Failed. (Note: If i used existing /etc/dahdi/system.conf . dahdi start and restart successfully).
10.Restart asterisk // successfully restarted.
After that call not connecting. Channels show 0.
What were your original system.conf and chan_dahdi.conf as well as your modified files? Are changing system.conf, you’ll need to re-run dahdi_cfg.
My existing/original system.conf and chan_dahdi.conf files were in following location:
/etc/dahdi/system.conf
/etc/asterisk/chan_dahdi.conf
After modified those were in same location and after changing system.conf file i hv re-run dahdi_cfg by dahdi_cfg -vv command.
Please suggest where was my mistake and let me know can i edit system.conf file manually directly ?
For your information, after re run dahdi_cfg -vv command . I have got like following error:
1 X X (In use) (EC: VPMOCT032 - INACTIVE)
2 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
3 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
4 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
5 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
6 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
7 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
8 X X (In use) (EC: VPMOCT032 - INACTIVE) RED
Assuming this is a current, genuine DIgium, product, the correct way to get support is through Digium’s commerical support channels. They will need the card serial number.
Is there any wrong of my process ? please suggest.
