Com21 Inc. has added two new DOCSIS 2.0 modems to its DOXport line of products — the DOXport 1110XB2 and the DOXport 1112XB2. The DOXport 1110XB2 modem comes equipped with additional features that support the requirements for synchronous-code division multiple access (S-CDMA) and advanced time division multiple access (A-TDMA) upstream modes of DOCSIS 2.0. The DOXport 1112XB2 offers the same capabilities but is designed for the Euro-DOCSIS standard. Used in conjunction with the DOXcontroller 1000XB CMTS, both models are capable of operating at up to 256 QAM upstream.
With Broadcom's 3348 chip as the base, the new generation modems feature the same Broadcom silicon tuner and a 200 MHz processor for improved throughput. Both modems are scheduled for release early in 2003.
