hey i was wondering why our T1 at work is so slow, it downloads at about 30 KB/S, we go through one company for our phone and internet, is this a f@*K up on their part or is this the speed i should be expecting?

    No should be hella faster then that. However they may have limits on how it's split up throughout your network so no one person can hog the bandwitdh. Just ask your admin.

    Just because you have a T1 doesn't necessarily mean you have the full T1 bandwidth. T1 providers offer "channels" - a T1 is split into 24 channels of 64K each. Each voice line is 64K, and depending on what your employer wants to pay every month, they can choose exactly how many channels they pay for.

    So, they might only be buying 512K or 384K off of a full T1. It's a lot cheaper than the entire 1.5mb available.

    If you are getting 30 Kbytes per second that translates to 240 kbits per second. So if everything is working right you most likely have either a 256 k line (4 channels) or a 384 K line ( 6 channels) and something is using the other bandwidth.

    there's about 10 phones running off this thing too (each one is one of those types that you can have several people on hold or talking) , so does each phone take some of the bandwidth too even if we're not using them?

    we're a small buisness so we don't have an admin, i guess the best thing to do is to call our provider and ask them about our account, cause i'm sure as hell no one here knows.

    Are you sure you have a t1 and not say a 2mb fibre optic line for example. Your phones and your t1 are 2 seperate lines.

    Not true. I have a single T1 coming into my office, with 4 channels split off for voice and another 12 channels for data. A single T1 can handle both voice and data traffic.

    Youvegotjermz: The phones take up no bandwidth when they are idle. They don't really take up "bandwidth" per se, as the channels are split off before the lines are turned on. So, no matter what, the voice and data are seperate. However, many providers offer "bonus bandwidth" (mine does this).. With a modern Adtran unit or whatever, the bandwidth that is idle when there are no phone calls taking place can be allocated to data. So, I have a 768K T1 (12 channels), but have an additional 256K of "bonus" bandwidth when nobody is on the phone. Take off a few K for overhead for the voice buffer and all that, and I actually have about 900K for most of the time.

    Cool at the companies I've been at anytime they wanted to get a T1 line run, or were entertaining the thought they were always told they had to get a seperate line run. Which just killed that idea.

    I didn't know that was how a T1 worked... you learn something new every day. That also explains why T1 upload speed matches T1 download speed. It ends up being, essentially, an advanced form of ISDN - correct?

    pretty much. I mean, they are both digital, they both are channelized, but architecturally they aren't very similar. But yes, as an ISDN is 64K per channel as well, that is a similarity.
