Hi all, Quick question regarding channel banks, I managed to confuse myself ( monday...daylight saving time...no coffee ). If I have 10 copper wires coming in from the phone company, and I want to get a channel bank that will turn those into a t1 to feed into an * box with appropriate hardware, do I want an FXS or FXO channel bank? While I'm at it: Are there specific features I should be looking for? Is there a specific company everyone's had good luck with? Any recommendations on this or otherwise? Thank you. Sean
Daylight Saving Time confused me as well!!! I'll make it simple: FXO ports connect to a phone company line, can be referred to as "O"ffice FXS ports connect to a phone device, can be referred to as "S"tation What kind of features do you want in a channel bank? Not many!! Good channel banks are pretty simple devices. I prefer and recommend an Adtran 750. It has modules that you can change between FXS and FXO. I would look on EBAY for one with 3 FXO cards and 3 FXS cards, that will give you 12 Office lines and the ability to connect 12 analog devices to it as well. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Sean Kennedy Sent: Monday, April 04, 2005 5:40 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] Channel bank question Hi all, Quick question regarding channel banks, I managed to confuse myself ( monday...daylight saving time...no coffee ).

Any > recommendations on this or otherwise?You want CPD (calling party disconnect, also know as far end disconnection, disconnect supervision, etc.). On FXS it doesn't matter but on FXO it's a critical feature IMO. Carrier Access ABI and ABII do not have this feature. CAC's Adit600 does. I don't know about the others. -A.

You want to call your telco and see what the cost of a PRI (T1) is to replace those 10 lines. You have 10 analog lines should be at the point where it is about a break even, if not call a competitive carrier. You do not want to use a channel bank to convert analog to digitial, even if it could be done you are putting bandaids on a huge wound. You will get a lot of features with the PRI you can not get on analog, not to mention it will work, what you are talking about doing makes no sense from a practical standpoint. Do it right, get a PRI and a single PRI digium card (or another PRI terminating device like a T1 chabbel bank)/

You need a channel bank that has at least 10 or 12 FXO ports. I recommend an Adtran 750 or 850. You can get them on EBay for around $ 400 to 500. But most are pre-configured with FXS. You will need to either switch some of those card out. Then you just put in a T110p card into the asterisk. Also if you get this C/B with 12 FXO you can have the other 12 with FXS for normal analog extensions. While I'm at it: Are there specific features I should be looking for? Is there a specific company everyone's had good luck with? Any recommendations on this or otherwise? Thank you.

You may be in luck!!! The Adtan 600 line does have a DSX-1 module available. (you gotta love Adtran!!) http://www.adtran.com/static/docs/64200612L28.pdf Now all you need are a buch of IP phones and your rocking!!!! Trash the CB plan go Digital!!!! -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Sean Kennedy Sent: Tuesday, April 05, 2005 12:47 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Channel bank question Damon Estep wrote:>>-----Original Message----- >>From: asterisk-users-bounces@lists.digium.com >>[mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Sean >>Kennedy >>Sent: Monday, April 04, 2005 4:40 PM >>To: Asterisk Users Mailing List - Non-Commercial Discussion >>Subject: [Asterisk-Users] Channel bank question >> >>Hi all, >> >>Quick question regarding channel banks, I managed to confuse myself ( >>monday...daylight saving time...no coffee ). >> >>If I have 10 copper wires coming in from the phone company, and I want>>to get a channel bank that will turn those into a >>t1 to feed into an * box with appropriate hardware, do I want an FXS >>or FXO channel bank? >> >>While I'm at it: Are there specific features I should be looking for? >>Is there a specific company everyone's had good luck with? >>Any recommendations on this or otherwise? >> >>Thank you. >> >>Sean >> >> > > >I am assuming you are in the USA, correct me if incorrect. >Correct.>You want to call your telco and see what the cost of a PRI (T1) is to >replace those 10 lines.

I have one provider who is brave enough to ATM a t1 out to my location. Everybody else won't touch us. Currently, we have what our vendor is calling a burstable t1. I don't know if this is a common term or not, but bassically it means voice and data share the t1, voice eating into the bandwidth as needed. The t1 is actually terminated into an Adtran 616 which I am currently researching to see if it can feed out a t1 feed instead of the 10 copper lines. But I digress.>You do not want to use a channel bank to convert analog to digitial, >even if it could be done you are putting bandaids on a huge wound. > >Agreed.

However, this situation is different given the line costs.
