> Admittedly, the terminological and conceptual barrier may present<br>> some<br>> impediments to the completeness and specificity of answers, so we<br>> might<br>> have to work at this a bit, but let's see how we can help:
<br>><br>> On Tue, 10 Apr 2007, James R. Stevens said something to this effect:<br>><br>>> We have a T1 coming into the building(FYI-Our Voice and Data are on<br>>> separate T's) terminating at the Smart Jack.
<br>><br>> Are you implying that there are two T1 circuits -- one voice,<br>> and one<br>><br>> data? Or do you mean that the T1 is channelised and some of the<br>> channels<br>> are used for voice and some for data? That's kind of what it sounds
<br>> like.<br>> Sounds like you can do 7 calls on voice channels and the rest are<br>> provisioned as a clear-channel data pipe.<br>><br>> That would mean that you have some equipment for breaking them<br>
> out on<br>><br>> your premises. The channel bank would break out the voice lines as<br>> FXO<br>> analogue lines (if you set it to) and those probably feed into your<br>> PBX.<br>><br>> The rest of the channels used for data would probably be signaled
<br>> out on<br>> another T1 interface, but with some subrate DS0 channels missing.<br>> That's<br>> ust a guess.<br>><br>> But what you say below suggests that my theory is wrong, so perhaps<br>> it is
<br>> the case that you have separate voice and data T1s after all, even<br>> though<br>> you refer to it in the singular.<br>><br>> Do be aware that under no circumstances does anyone generally refer<br>
> to a<br>> T1 as a "T." :)<br>><br>>> I can tell you our current phone system can handle 7 phone calls at a<br>>> time:<br>>><br>>> Does this mean the T only has 7 channels provisioned out of the 24
<br>>> possible?<br>><br>> This is possible. Do you happen to know what kind of signaling is<br>> used<br>> on it? Is it an ISDN PRI, or an E&M trunk?<br>><br>>> Does a channel (In terms of the T1) = a port?
<br>><br>> A port on what? The channel bank?<br>><br>> Channel banks generally do break the DS0s (subrate 64 kbps<br>> channels,<br>> of<br>> which there are 24 on a T1) out, but some more sophisticated ones have
<br>> the<br>> capability to do other things as well.<br>><br>> If so, the answer is yes.<br>><br>>> How many phone calls can one TDM400 support concurrently? (four ??)<br>><br>> If it has four FXO ports and four FXO modules, yes. They come in
<br>> different combinations. Some come with 2 FXO (outside POTS lines<br>> to CO)<br>><br>> and 2 FXS (plain analogue POTS handsets) ports, etc.<br>><br>>> Would I be better off getting a Zapata T1 card and forgetting the
<br>>> Channel bank all together(Use the digital signal)?<br>><br>> You could do that. Personally, the easiest approach I would say<br>> would be<br>> to order a PRI. They've probably considerably gone down in prices,
<br>> too,<br>><br>> especially if you go shopping with some friendly CLECs. The rule of<br>> thumb<br>> in the industry is that generally, once you pass the threshold of<br>> six or<br>><br>> seven POTS lines, it becomes economical to just order an entire
<br>> PRI, and<br>><br>> once you do that, there usually aren't *very* considerable savings<br>> to be<br>><br>> gained from turning down all but a few channels. A PRI has 23<br>> channels<br>> (bearer channels ("B channels")) and one signaling channel ("D
<br>> channel");<br>> it's a type of T1-based ISDN interface.<br>><br>> So, you might potentially be able to get 23 in/outbound phone lines<br>> for<br>> roughly the same cost or a modest increase, which would increase your
<br>> organisation's capacity to do things like conference calling and other<br>> things which tie up large amounts of outside lines.<br>><br>> Do beware that if you go this route, PRIs can be ordered as
<br>> "inward-only"<br>> (typically used for modem and termination-only telephony applications<br>> like<br>> voicemail, IVR, conferencing, etc.) or bidirectionally.<br>><br>>> If we go with a Zapata T1 card for the Asterisk server would we be
<br>> able<br>>> to provision an analog phone line, for say a FAX machine from it?<br>><br>> No, not if the card doesn't have FXS ports on it. But you could<br>> get<br>> another Digium or Digiumlike card that does, even if it's just a
<br>> single-port (like the hugely popular X100P, which is very inexpensive)<br>> and pull that off.<br>><br>> Let me know what else we can answer, or if I substantially<br>> misunderstood<br>> your question.
