61221002L2-5B 1 ADTRAN ® AHDSL2 Asynchronous H2TU-C Line Card for Alcatel Litespan ® Channel Bank Assemblies Using Narrowband Pairs Installation and Maintenance Practice Section 61221002L2-5B Issue 2, August 2003 CLEI Code: SLL5R3DG_ _ CONTENTS 1. General .
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.
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.
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.
