The H2TU-R-402 List 7A (H2TU-R) functions as the remote end of a repeaterless T1
transmission system when connected to a HiGain
®
, Soneplex
®
, or LoopStar HDSL2
line unit (H2TU-C). Setting new standards for interoperability and efficiency, HiGain
HDSL2 modules transmit 1.544 Mbps T1 payload on one unconditioned copper pair
over the full Carrier Service Area (CSA) range.

either the LPS-H2C-L7A, H2TU-C-231-L7A,
H2TU-C-319-L7A, or H2TU-C-388-L7A to be used as the
corresponding line unit.

NSTALLATION
1
Configure the H2TU-R for line or local power, as follows:
•
For line power, place a jumper on pins 2 and 3 of P2 and P3.
•
For local power, place a jumper on pins 1and 2 of P2 and P3.
2
Check the setting of the Sealing Current (SCURR) jumper (P1). The default
setting is disabled (jumper on pins 2 and 3). If the H2TU-R is locally powered
and your application requires sealing current, place a jumper on pins 1 and 2.
3
Align the H2TU-R with the enclosure slot guides and slide the unit in. Push the
unit back until it touches the backplane card-edge connector.
4
Place your thumbs on the front panel and push the H2TU-R into the card-edge
connector.
Continued
Wear an antistatic wrist strap when installing the H2TU-R.
Avoid touching components on the circuit board.
