b. 800 calls must go out the analog lines, 800 calls CANNOT go over the T1, it against the law, and most CLEC's and LD carriers will not complete the call if sent over the T1 span.

What about if one has a ISDN-PRI into the KX-TD1232, perhaps with an Ascend router or equivalent between the CSU/DSU and the KX-TD1232?
Things start to look economically feasible if we can bundle the LEC charges (200 $/month) with internet access (55$/month for 1500/128 ADSL via PPPOE dynamic IP) and maybe reduce long distance (220 $/month) too.
I am beginning to see why some people hire a consultant to help decide which telecommunication suppliers to select.

Here's the skinny on T1 since I've done one on a TD1232, and numerous others on other systems.
1. TD187 module is required for T1 it provides 24 channels w/ 8 analog lines
per system, (single/dual cab)
( A channel bank could be used, but I personally feel, if you are like to
mess with lots of wires,and punch blocks and cross connect, and have
Napoleonic visions of a large PBX room as your office, then they are ok. Most of my customers have limited space, and want a minimum of stuff hanging
everywhere, so I opt for the TD187. Conversely, the price of the channel
bank , and all the TD180 CO modules you'll need, plus the dual cabinet to
contain all the analog lines far exceeds the cost of TD187 module.
Especially, on a single cab system.)
2. A CSU is optional but in most instances required by the LEC or CLEC in MD it's required by law.( I would recommend a CSU.)
3. Programming on the TD1232 is slightly involved, and you need to know your terminology for implimenting it. B8ZS, AMI, ESF, etc. (if you don't know these, you'll need help, or refer to a qualified installer)
4. DID can be performed on T1, as well as TIE lines. No Caller ID (CLID). DNIS is provided for the DID.
5. Tarriffing for LD is usually on a per call, per minute charge with incremental billing, as well as a per month charge for the line. typically $500/mth, 5c/min, 6s increments
6. 800 inbound can be applied to the T1 with similar cost as the LD. Advantages to this is an increase of inbound coverage with the 24 channels.
7. The T1 can be split by the most LD companies or the CLEC for outbound/inbound (examples being 12in/12out, 20 in/4out, etc.) This would depend on your business app.
8. Analog lines are required for THREE reasons:
a. If the T1 span goes down, you have backup
b. 800 calls must go out the analog lines, 800 calls CANNOT go over
the T1, it against the law, and most CLEC's and LD carriers will not complete
the call if sent over the T1 span.
c. you still need analog lines for local inbound/outbound traffic9. Call centers obiously benefit from T1, if you are line heavy with lots of LD and inbound 800 traffic, they are great.
10. I have a very busy tech support center with multiple 800's coming into the location, a dual cab with the 8 analogs handing local tech support on 4 of them, with the other 4 for admin/sales calls. They have used all 32 lines available to them. We split the T1 for 16 inbound, 8 outbound. It works great, but it took 2 days to get the LD carrier to send me the correct DNIS info for call routing. They can be a bear to get running, but once they run, they run well.

I wish that there were a way to take a T1 (on which the ISDN-PRI is carried), split half for say 11B+ 1D channels, and use the rest (768K BPS) for internet access.
I have been involved with a good deal of video conferencing over the years where this is done quite frequently.
I was trained on this series of products when it was under the Ascend name: http://www.lucent.com/livelink/0900940380004901_Brochure_datasheet.pdf
I provides bandwidth on demand for phone, data, and video conferencing. Look at back view of Multiband MAX 6000. I has T1/E1/PRI to WAN or PBX. You can configure channel allocation to your hearts content.
Of course these units are far from cheap, but if you have a need for voice, data, and video conferencing with bandwidth on demand this is the magic box.
