3.9.2 Settings for Advanced Mode
Advanced Mode is the recommended mode for RLS implementation.
Note: When selecting Advanced Mode, both the “soft” failure mode (Basic mode parameters) and “hard”
failure mode (Advanced mode parameters) are to be configured.
3.9.2.1. RLS Signal Fault Settings
These settings correspond to “hard” failure mode The RLS signal fault settings are designed to detect and
react to brief bursts of extreme modem block error rates. The RLS signal fault detection and reaction time
is the quickest of the two RLS fault detection methods. RLS signal fault detection works with the RLS
signal degrade settings in Advanced mode.
set rls signal fault parameters [detect time] [percentage errored blocks]
The RLS signal fault parameters command accepts two parameters. [detect time] is the time, in
milliseconds, that the [percentage errored blocks] threshold must be met to activate RLS.
[percentage errored blocks] is the percentage of errored modem blocks to activate RLS on. For
example, the command “set rls signal fault parameters 1000 50” will activate RLS when 50% or more
of the modem blocks received in 1000 milliseconds are errored.
3.9.2.2. Recovery from a Hard Failure
Once a “hard” failure has caused an RLS activation, it uses the “soft” failure - RLS signal degrade
parameters – to determine the length of time to wait before reactivating the Ethernet ports.
3.9.3 RLS Link Control Settings
By default, the disabling and enabling of the data Ethernet port is automatically managed by the Horizon
Compact system in response to detected RLS events. It is possible to enable manual control of RLS
shutdowns, so that the data Ethernet port remains shutdown until a user explicitly re-enables it. There
are two commands that make up RLS link control, namely rls link control and rls link enable.
set rls link control [on/off]
To enable manual control of the data Ethernet port link state, set rls link control to on. The
default setting is off, allowing the Horizon Compact to re-enable the data Ethernet port once the
RLS condition is cleared.
set rls link enable [on/off]
When rls link control is set to on, the data Ethernet port remains in a shutdown state after the
RLS condition has been cleared. The Ethernet port can be manually re-enabled by issuing the
set rls link enable on command. The set rls link enable off command disbles the Ethernet
port.
