Loop-H3310 G.SHDSL

Distances vary by line speeds, wire thickness and
environmental factors, depending on max n.
E1, or V.35, X.21 DTE interfaces.
Uses industry standard 16PAM or proprietary 32PAM
line format.
Support line power
Support 1-pair or 2-pair G.shdsl lines
Software Download Firmware
Multi-color LED indicators
As slave to the Loop-H3300 master series
The Loop-H3310 provides high speed digital transport over
a single copper pair using standard 16PAM or proprietary
32PAM technology. Versatility of this series comes from a
choice of digital interfaces and a choice of line rates, with
the lower line rates applicable to longer reaches.
Repeaters are available for extending the reach beyond a
single span.

This stand-alone version is intended for customer premises installation only.

By installing in conjunction with a with
Loop-H3300 at the central office, Loop-H3310 can provide a high speed data link with DTE interfaces (V.35, X.21).
The Loop-H3310 supports configuration and diagnostics
from a local or remote terminal. This allows execution of in-service diagnostics and fault isolation.
