The H4TU-R-402 List 1 remote unit (H4TU-R) functions as the remote end of a T1
transmission system. The H4TU-R, when used in conjunction with an HDSL4 line
unit (H4TU-C), transmits a 1.544 Mbps T1 payload a maximum distance of 12 kft
over two unconditioned copper pairs (26 AWG). Using two HD4-409 List 1 doublers
(H4Ds), the Carrier Service Area (CSA) reach can be extended to 34 kft. (see

OMPATIBILITY
The H4TU-R-402 List 1 remote unit is compatible with ADC H4TU-C List 1 and
H4LXC Version A line units, and H4D-409 doublers. For information on HDSL4 line
units and the HD4 doubler unit, refer to the applicable document.

NSTALLATION
1
Set the S1 switches (SCURR and LPWR), located adjacent to the card-edge
connector, as follows:
2
Align the HRU with the enclosure slot guides, then push the unit in until it is
properly seated in the backplane.

. To order printed
copies, please contact your sales representative.
SCURR and LPWR Switch Settings
SC
UR
R
Disable (default)
Disables the flow of simplex sealing current from the upstream unit.
Enable
Enables the flow of simplex sealing current from the upstream unit.
LP
W
R
Line power (default)
Configures the H4TU-R-402 to receive power from the upstream line unit
over the HDSL pairs.
Local power
Configures the H4TU-R-402 to receive power from a local -48 Vdc supply. If
local power is not present, the HRU reverts to line power mode.
To comply with the intrabuilding wiring requirements of GR-1089
CORE, Section 4.5.9., the shield of the ABAM-type cables that
connect the H4TU-R-402 List 1 DS1 output ports to the cross-connect
panel must be grounded at both ends.
