2 61221002L2-5B Table 1 lists and defines the H2TU-C Front Panel LED indicators. Each ADTRAN Litespan H2TU-C line card provides a 1.552 kbps data transport over one unconditioned CSA copper pair. These CSA loops can range up to 12 kft of 24-AWG twisted pair wire. The Litespan H2TU-C can be used in Litespan 2000, Litespan 2012, and Litespan ONU chan[...]

61221002L2-5B 3 2. APPLICATIONS The ADTRAN HDSL2 system provides a cost-effective alternative for deploying T1 service over metallic cable pairs. In contrast with traditional T1 service equipment, ADTRAN HDSL2 can be successfully deployed over one unconditioned, nonloaded, bridged-tapped copper pair CSA loop (see Deployment Guidelines , Section 4).[...]

4 61221002L2-5B CAUTION Prior to installing or removing the Litespan H2TU-C, observe the following warning: If the Litespan H2TU-C is removed from a line card slot, wait at least 15 seconds before reinsertion. If connected to the MTI craft interface terminal, wait until the message “AID:MJ,UEQ.” appears (where “AID” is the access identifier[...]

61221002L2-5B 5 Provisioning Commands Upon initial insertion of the Litespan H2TU-C into the Litespan system, configuration options are downloaded automatically to the line card and take precedence over the ADTRAN default provisioning options. NOTE The provisioning options stored in the shelf controller can be pre-configured by the user through the[...]

61221002L2-5B 7 Testing Commands The H2TU-C testing commands are used to initiate and terminate loopbacks and disconnect for testing purposes. Table 8 lists and defines the TL1/Litecraft testing commands. NOTE Before entering loopbacks, the user needs to remove the card from service. This can be done with the RMV-HDSL command. The card can then be [...]
