I understand that when you hook up to Telenet, you automatically lease a Paradyne 9600 baud sync modem. Can anyone tell me if this modem has any features not available in the AT&T 9600 baud sync modem, especially things like remote diagnostic capabilities? Are the protocols compatible? In other words, would an AT&T modem work plugged into Telenet? Mark

I imagine the Paradyne model used is the MP-96 (or compatible). The MP-96 is a V.29 compatible modem, so it will talk to any other V.29 modem. However, this is for the main channel only. Paradyne has a quite extensive diagnostics system which runs in the sideband, and I imagine that this is why Telenet recommends (demands) this model. At my former job, we ran the Paradyne system, but later quit buying new modems for the "Analysis" system because the diagnostics were too expensive. For example, for less than the price of a single paradyne modem we could buy TWO Rixon R-96 modems, which, being V.29 compatible, would still act as spares for the Paradyne modems. Now, with Halcyon's $995.00 V.29 modem, the Paradynes are more than three times as expensive. Diagnostics are awfully nice, but, for something as simple as a modem, there is an economic upper bound! In summary, there are two answers to your question. Yes, other modems will talk to the Paradynes, and the answer to whether the AT&T modem will talk depends on whether it is V.29 compatible. HOWEVER, since they provide the network control. it is questionable whether the Telenet POLICY will allow this. (Please post the results of this interaction with Telenet to the net. I think their monthly cost includes modems. Any idea whose modems AT&T's Accunet specifies/requires?)
