1. GENERAL
The ADTRAN T200 Low Voltage HDSL Unit for
the Remote end (HTU-R), ADTRAN part number
1246026L6, is a network terminating unit used to
deploy an HDSL T1 circuit using 4-wire metallic
facilities. The HTU-R is a T200 mechanics card
which will fit any T200 or T400 mechanics
enclosure. This includes the ADTRAN standalone
metal enclosures (P/Ns 1242034LX), the ADTRAN
HR12 HDSL remote shelf (P/N 1242007LX), or the
ADTRAN HR4 HDSL remote shelf (P/N
1242008L1). Refer to appropriate ADTRAN
practices for more information.
This version of the HTU-R works with multiple list
versions of the HDSL transceiver unit for the central
office (HTU-C), and HDSL Range Extenders
(HREs) as listed on the next page.
