Cable vs. V.90 modems
Cable modems emerged in consumer markets as an alternative to ISDN and regular modems only a couple of years ago. Promises like speed up 30 Mbps to connect to the internet sounds very attractive given that the service charge is only $35-$55 a month. But the whole thing has been overhyped in my opinion, none of the cable companies mention that the subscribers share the bandwidth plus most cable modems use 10BaseT interface to connect to the PC or Mac which automatically limits the connection to 10 Mbps. Another limitation of cable modems is that ISP’s are connected to the internet back-bone using T1 lines which puts an absolute limits on speed of cable connection to 1.5 Mbps The cable modem access network operates at Layer 1 (physical) and Layer 2 (media access control/logical link control) of the Open System Interconnect (OSI) Reference Model. Thus, Layer 3 (network) protocols, such as IP traffic, can be seamlessly delivered over the cable modem platform to end-users.. Since cable modem technology is very recent the conflict exists between different standards. The only specification that has been approved by ITU (in 1998) is DOCSIS (Data Over Cable Service Interface Specifications) which was developed by MCNS,
