The H2TU-R can be deployed in circuits using one
H2TU-C and one H2TU-R.
The H2TU-R terminates local loop HDSL2 signals
originating from the Central Office (CO) unit and
transforms the HDSL2 signal into traditional DS1
signals to be delivered to the customer.
The H2TU-R (P/N 1222026L7) can be used with any
H2TU-C to complete a fully span-powered HDSL2
circuit. Span power is provided from the H2TU-C. Span
powering meets all requirements of Class A2 voltages as
specified by Bellcore GR-1089-CORE. This unit is
intended for Span Power Only. If a locally power unit
is needed, refer to P/N 1222024L7.
