H2TU-R-402
The H2TU-R-402 remote unit is the customer premise side of a transmission system.
The HiGain HDSL2 product family is fully compliant with the HDSL2 standard and
ANSI T1/E1.4. Providing full-rate T1 access using just a single copper pair, HDSL2
is a cost-effective solution that offers an open architecture. The open architecture
inherent in HDSL2 guarantees interoperability, allowing simple and economic
accommodation of network growth.
HiGain HDSL2 products provide 1.552 Mbps transmission on one unconditioned
copper pair over the full Carrier Service Area (CSA) range. The CSA includes loops
up to 12,000 feet of 24 American Wire Gauge (AWG) wire or 9,000 feet of 26 AWG
wire, including bridged taps.

NSTALLATION
1
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.
2
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.
When local power is applied to this unit, it automatically
provides a resistive termination at its HDSL2 port. This
termination will sink 10 mA of sealing current when
connected to a list 3E or higher line unit.
