By Peter Rysavy Standards are becoming ever more important in the networking industry.
Standards allow products from different vendors to easily interoperate.
The PCCA Standards Committee is playing an important role in setting open standards for the wireless industry and its latest standard, Annex L, is a significant milestone. The PCCA Standards Committee passed Annex L at its September 25 meeting. An immediate question is why do CDPD modems use AT commands if they are packet-mode devices based on the IP networking protocol. The answer is simple. Consistent with PCCA standard STD-101, CDPD modems can operate either in a command mode or in a data mode.
