Post by w***@gmail.comI would like to setup one work environments with fax internet and
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.
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.
