LPS-H2C-L7A
HE
The LPS-H2C-L7A is a low-power, HDSL2 plug-in line card that installs in a
™
LoopStar
Chassis, Soneplex
Chassis (BBC), or Soneplex Integrated Broadband Chassis (IBBC). To ensure proper
operation, the LPS-H2C-L7A line unit requires the H2TU-R-402-L7A as the
corresponding remote unit. The system provides 1.544 Mbps full-duplex transmission
on one unconditioned copper pair over the full Carrier Service Area (CSA) range. The
CSA includes loops of up to 12,000 feet on 24 AWG wire or 9,000 feet on 26 AWG
wire, including bridged taps.
