Please log in for more thread options phones. I have a Avaya ip office Pbx and 2 fax machines and internal firewall servers. I read that one T1/PRI line can be use for voice, fax and internet. so i think i can use 8 channles of T1 for internet and 2 for fax and remaing channels for phone. My PBX has one T1/PRI trunk port. How can i achive this? T1-inband can be configured for the same? Any devices are required. Please help. | ||||||||||||||||

Please log in for more thread options It can, but this is probably the most expensive, most painful way to do it. ISDN is a dialup technology, if you are going to be doing internet access over ISDN, you'll be dialing up over each 64k channel, and bonding them together with some method. MLPPP works, but maxes out in most implementions at 8 channels as you say, but remember, thats only 512kbps (minus whatever overhead). There's not going to be any ISP that is going to be interested in chewing up 8 dialup channels for you to do this though, they'd rather have some sort of dedicated solution. All telcos offer some sort of integrated voip/data T1 solution now-a-days. They'll be doing a little more advanced features rather than straight-up ISDN. Frequently they can offer setups like all channels in use for data until you get a voice call, and it'll either steal data channels as needed, or do some sort of voice over packet with dedicated bandwidth for each voice channel in use. They'll take care of all the hardware and setup needed, handing off your PBX and ethernet feeds to you at the demarc. Since you'll have to match whatever hardware is in use anyway at the other end, this is usually the cheaper/easier way to go. So, shop around to the various telcos in you area asking about integrated data/voice T1s with Internet access and get some priced out. Ask about hardware, but assume they'll take care of it all and hand you back just what you need. Some of the CLECs will be very agressive for all parts of this type of solution, while the ILEC probably will price themselves out of the market. | ||||||||||||||||
