I happen to work for a manufacturer of data comm equipment. We are working on a new product and are looking seriously into the possibility of an ISDN interface. Since this product is unannounced, I can't be too specific about it. What we are planning is a 2B+D interface (the basic user TE1 / NT setup) for the new product. Documentation I've found about ISDN often leaves out basic things like electrical specs for interconnection to the telco, etc. Also, there are several competing chip sets on the market. For example, has anyone had any experience with the AT&T T72xx series? I guess what I'm wondering is if any other vendors care to share any words of wisdom about doing ISDN for real in a commercial product. One thing we are rather painfully aware of is that we have sold equipment to various phone companies for other purposes and they are real gung-ho on ISDN in future products.
