Thus, the subscriber can access the ATM/IP backbone or the Internet to enjoy services such as high-speed data communication and video on demand (VoD). ADSL transmits data in the high frequency band above 26 kHz. Therefore, it can provide services without interfering with the voice service being provided in the low frequency band (0 to 4 kHz) on the same line. It provides downlink rates in the range 32 kbps to 8 Mbps and uplink rates in the range 32 kbps to 1 Mbps. The ADSL interface cards provide these functions: z Manual ADSL line activation and deactivation, supporting SAR loopback for convenient fault isolation. z Interface standards of G. DMT, G. Lite, and T1.413, auto-sensing. z Trellis coding (except for G. Lite) on ADSL interfaces, enhancing stability of ADSL connections. 3.12.2 Interface Attributes The following table describes the interface attributes of the ROUTER 2-PORT ADSL OVER POTS MIM.
