HIGH-SPEED VOICE AND DATA LINK (HVDL) 3.1
HVDL 3.1 enables a single copper pair to deliver three voice channels and one
high-speed Ethernet data channel to small business and residential subscribers
on loops of up to 56,000 ft. Utilizing low-noise, low-power TCPAM (G.shdsl)
line coding, the system multiplexes three 64Kbps clear channel voice lines and
one 1Mbps symmetrical data line for transport, then demultiplexes at the
subscriber site via a line-powered remote terminal. HVDL is the ideal way to
bring DSL to remote and low-density areas with minimal start-up costs and
pay-as-you-grow scalability.

Timing and Synchronization
TIMESOURCE
®
2700, 3000 AND 3500
The TimeSource 2700 is a CDMA Primary Reference Source (PRS) providing two
precise synchronization outputs. The system antenna mounts inside the
building, dramatically lowering installation and maintenance costs. Stratum 1
holdover is provided for up to 21 days, if CDMA signals are disrupted.
The TimeSource 3000 is a GPS PRS providing up to 10 precise synchronization
outputs. The system uses a standard roof-mounted antenna. It provides
undisturbed Stratum 1 synchronization when locked to four GPS satellites, with
continued Stratum 1 performance for up to 72 hours upon loss of GPS.
The TimeSource 3500 is a GPS PRS that uses an antenna mounted inside a
window. The unit needs a single satellite in view for as little as 10 hours per
day. Up to 10 precise synchronization outputs are provided with Stratum 1
holdover for up to 21 days upon loss of GPS.
