Voice T1 or Data T1
As we’ve stated many times before a T1 line physically looks the same in terms of bandwidth, frame rate, clock rate, etc, regardless of what type of information it ultimately transports. So this being the case can’t you just get a T1 and use it for what ever you want? Unfortunately not. We have talked about PRI T1 previously and if you can get this for a small premium over a voice T1 or a Data T1 then that is by far the most flexible solution.
So what is the difference between a Voice T1 and a Data T1? The only major difference is what the T1 is terminated by at the Central Office or switch. If you want a voice T1 then the provider will physically connect your T1 line to a voice only Line card in a switch such as a 5ESS that Lucent Technologies sell in the US. If you need only data then you maybe connected to a physically different piece of equipment such as a Cisco 7500. These cards and equipment are simpler and have less software than a PRI T1 termination line card, hence Voice or Data T1 lines tend to be cheaper but of course you loose your flexibility.
Obviously as user you don’t really care what is at the other end of the T1 line but it is important for you know what sort of T1 you need and want. Let the WhichVoIP team help you get the solution that’s best for your business - Free T1 quote.
