    ADSL. 1.2 ALC1224 Overview The ALC1224 (ADSL Line Card) provides ADSL service for 24 subscribers over existing telephone wiring, thus avoiding the cost and hassle of installing new wiring. ADSL allows you to extend the reach of broadband services up to 18,000 feet. This makes the ADSL line card perfect for providing high bandwidth broadband service to subscribers who are spread out over a large area.

    13.1.1 Supported MIBs The ALC1224 supports the MIB II IF MIB and ADSL line MIB (RFC-2662). MIB II is defined in RFC-1213 and RFC-1215. The ALC1224 can also respond with specific data from the ZyXEL private MIBs (zyxel.mib, zyxel- AS.mib, zyxel-AS-ATM.mib and zyxel-AESCommon.mib). MIBs let administrators collect statistics and monitor status and performance.
