Actually, up in Boston, MFS derives all their pricing by taking the Nynex end-to-end price and subtracting a certain percentage (at least 10%). I may be mistaken but, I think they still do this even with the DS3 Hub. You still pay two chan terms. A Nynex chan term is about $200 so this ends up being quite an expense. The overall savings still makes it worth while if you are going to sell a lot of T1s - if only for the headache, you only need two aspirin at the end of the day instead of four.

1. Cisco serial ports and rack CSU/DSU's. Exspensive. Lot of space. Cisco has a channelized DS3 card. Wire once to dacs and provision in software only.
2. MAX TNT for T1's connecting to a backbone Cisco. Theoretically up to 140 T1's in 1 small box with built-in CSU/DSU's. Unproven?
Vary.
3. Cascade. Similair to TNT approach, very exspensive untill you reach 70+ T1's in a chassis. Cascade has a channelized DS3 card as well. Good for combining many customers who have a physical T1. Split out at the dacs.
Yes tend to be big bucks, but is not that bad if you have many T1s to terminate.
4. Chanellized DS3. Don't know anything about it - can MFS provide circuits this way via a DS3 handoff? No CSU/DSU required? Any other costs/issues? Channelized DS3 stuff only seems to be useful for putting mulitple customers on a single physical circuit. You need to be able to break it out to the DS1 level for each customer. Perhaps MFS, PacBell, etc can do this? It's probably just a matter of them defining that "product". (I.E. Feed MFS a DS3 and they give a T1 to each of your customers.)
Yes, the Cascade and Cisco CT3 have a built in M13 built in. All you need to do is order a DS3 HUB into the providers you want. What we do is run a few DS3s into the COs in our area. You may want to run a DS3 into a few telcos also. They can you get the best price for your customers.
DS3 HUBs can be a little on the high side, but they more then pay for themselves. Say you run a DS3 HUB into Bell Atlantic, you spend around 3K for the HUB. When you order your customers T1s you only order a 1/2 channel term. So you can more then pay for it with around 9 - 13 DS1s.
