The panels of HS-R modules include two status indicators for each channel:
• The TEST indicator lights up when a loopback is activated on the
corresponding channel.
• The LOS indicator lights up when the corresponding channel looses V.110
protocol synchronization to the remote end. Note that when the channel
operates at 64 kbps, no framing is used, and thus the LOS indicator lights
when the Megaplex main link loses synchronization.
The HS-R module panel also includes two 25-pin D-type female connectors, each
serving two channels.
All the functional configuration parameters of the modules are determined by
software. Jumpers are used only to control the connection of ground reference to
each channel.
