I need to interface a T1 circuit directly into a VME based machine. The idea is to take the T1 circuit and feed it into the computer and twiddle the bits. In other words the computer will perform the functions of a DSU and T1 mux. I am trying to find a VME board that understands T1 signaling and framing. Does anyone know where I might find such a critter? While I am on the subject of T1 and serial IO I have a couple of other questions that the TELECOM Digest readers may be able to answer. 1) Can someone provide me with the names of the standards that define DS0, DS1, etc. I believe that in the old days DS0, DS1, etc were defined by AT&T's documents but I seem to recall that there is now an ANSI spec. 2) Does anyone know of a VME serial board that can handle a ~600kbps unformatted data stream? By unformatted I mean that there is no framing at all. The data consists of a raw bits and a clodk.
