Greetings list, I've been asked to provide a system for 200 extensions, most of which will be existing analogue POTS handsets, not IP handsets. I've not really had any experience with large channel banks in the past (since most of our deployments are strictly IP-only to the desk), so I'm at a loss as to which ones are worth looking at. If anyone's had experience using channel banks on reasonably sizeable installs I'd be interested to hear what device(s) you used, how simple or complex they were to configure, and whether there'd be any issues attaching multiple units to a single server. This install would be in the UK, so we do need to factor in the different conditions expected by UK POTS handsets (line impedance, etc.). Are most channel banks country-neutral, or do specific models need to be purchased for different line conditions in each country? Thanks in advance. Regards, Chris -- C.M.

I have been told to use Rhino Channel Bank but I am yet to set it up and I appreciate if someone can show me some doco of using Rhino on an E1/T1 with TE410.

> Any luck with the channel bank?Thanks for the reminder Paul but so far no luck. I have been getting: 1) *** Initialising: Trying to frame D4 / ESF on the channel bank 2) Red flashing light on port 2 of the TE412P card I have checked a few things here and there but I think I must have missed some basic stuff. The funny thing is before I purchase the Rhino channel bank, I have been assured that it will work although we are using E1 downunder. Here is my configuration: Asterisk box TE412P Port 1 <---> E1 Port 2 <---> Rhino 24 port FXS (CB24-FXS-UNIV) Port 3 Port 4 [zaptel.conf] # # E1 # span=1,1,0,ccs,hdb3,crc4 bchan=1-15 bchan=17-21 unused=22-31 dchan=16 # # Rhino 24-port Channel Bank # span=2,0,0,esf,b8zs fxols=32-55 Any thoughts?
Have you tried setting the card as being T1 instead of E1 for the port connected to the channel bank?

I assume span 2 is set ti T1... Also you should be using a crossover if your going from the card direct to the channel bank. Remember an RJ48 crossover and an RH45 crossover are not the same.. It you are using an RJ48 crossover and your span 2 is T1 then try auto T1 If All else fails you can contact support...

Good to here, I know the time off set US -> AU is terrible when you need support.
