We currently have 16 lines in my test facility. These lines are Centrex lines and we get them very cheap ($10 per line), I can not cost effectively move over to a PRI, so I purchased a channel bank from eBay with a couple FXO cards. Each card can handle 8 lines. The PRI connects to the channel bank and the phone lines to the channel bank. Doug

[Asterisk-Users] Fw: Channel Banks, what are they for?

Basically, channel banks save time, energy, space and wiring mess. They also often give higher FXO/FXS interface quality as well. They cost a little more but IMO if you take everything into account they are by far cheaper in the long run. Anyway as mentioned channel banks are an easy/cheaper way to aggregate lines. Instead of having 24 Sipura boxes or 6 TDM400P cards and all the wiring mess that goes with it, you have a single T1 card and a single cable going to a single channel bank, which will have a single D50 connector that you can terminate directly to a single BIX punchdown strip. Channel banks are also typically (much) higher quality than the cards or low-density ATAs you can buy. I am particuarly fond of Carrier Access Adit600s. -A.
Kind of the idea I got.. So then I could take a channel bank and feed my PRI from the telco into it then on the other side I would have a bunch of RJ11 ports to use as normal analog type phone lines? What about this situation... I have a PRI going directly into an Asterisk box now in a location using a TE110P card. What if I wanted to pull off a few of those 24 channels to use for fax lines, dialup internet testing lines etc.. Would this be a job for a channel bank? If so, could you explain how a channel bank, and my Asterisk box would be setup to do something like this? --Todd ----- Original Message ----- From: "Andrew Kohlsmith" <akohlsmith-asterisk@benshaw.com> To: <asterisk-users@lists.digium.com> Sent: Sunday, October 02, 2005 8:31 AM Subject: Re: [Asterisk-Users] Fw: Channel Banks, what are they for?> On Sunday 02 October 2005 09:09, Mojo Jojo wrote: >> > Can someone explain to me what a channel bank is used for? >> > >> > For example, if I had a 24 channel PRI setup with an Asterisk box >> > attached to it via a TE110P, how would a channel bank make my life >> > better? >> > >> > Anyhow, I just have not clue and thought someone could tell me the >> > purpose of these devices. > > A channel bank is a device used to aggregate (or break apart) individual > FXS > and FXO ports to/from a T1 connection. > > Basically, channel banks save time, energy, space and wiring mess.
