73M2901CE Canal+ Compatibility

By: Jeff Sorensen

摘要 : The Teridian 73M2901CE is a V.22bis single-chip data modem for devices that require transferring data over the public switched telephone network (PSTN). Canal+, a major digital television service provider, uses a V.22bis or V.23 modem for Pay-Per-View, access to online services, and other interactive TV applications. The 73M2901CE's combination of dedicated features, Hayes commands, and S registers makes it perfectly suitable for Canal+ applications, with few or no alterations at all. This article describes the compatibility and divergences between the 73M2901CE and the Canal+ requirements, as described in a Canal+ document \"Hardware Specifications for Media Basic Box V3.01.\"
