The 802060 Dual T1 HDSL WAN Card has two ports that that are equipped with 82100 T1 HDSL modules. The
HDSL modules provide 1.544 Mbps T1 transmission over 2 copper pairs. Both modules have to be installed for
proper operation and do not support redundancy. Table 9 depicts the various T1/E1 WAN card specifications. In
addition to the specifications listed in Table 9 (below) the 802060 card is in conformance with ITU-T Q.421 and
ITU-T Q.422. The transmission range is software selectable for the following: 0, 133, 266, 399, 533 or 655 ft. (up
to 200 meters), and CSU (allowing connections to the equipment side of a co-located external CSU over a short
distance, four-wire cable). Software selectable line build out (LBO) settings are also available for all of the
aforementioned transmission ranges.
