Since you said MCI, it is interlata, and getting the long haul part as a 64kb DS0 is probably EXACTLY the same price you are paying for analog today (tis so with AT&T). The LEC tail cks may cost more, but try for them under the new DDS-II class tariff. It MAY cost about the same to get 64kb digital as your analog service. If the local turkeys haven't filed for 64kb, but do have 56kb with secondary channel, order that and use good CSU/DSUs that can do 56kb, 56kb w/sec, 64kb, (plus probably all the lower speeds, too). The clear channel they provide for those secondary channel bits (that I doubt you want to use that way) will 99+% sure let you click the switch from 56kb w/sec over to 64kb and simply run. Wouldn't you really prefer 64kb with NO analog modems?? 2.4 - 64kb CSU/DSU maybe costs $700. Many vendors still stop at 56kb, but get them from the more progressive sources. > > You could also spend $6600 and buy a ethernet to 9600 baud > bridge to place on each end.

Enet bridges that will do 64kb are well less than $2k, and by the time you get to < $3k, count on T1 or E1 speed. You have a choice of vendors. Times are changing. For starters try NAT ( n.b. not NET ) at 800.543.8777 in CA you may need 408.733.4530. There are others.
