Configuration and Monitoring
Fixed 270M/Mute Mode
In this mode, the electrical inputs are equalized and fed to the reclocker. If
the bit rate is analyzed as 270Mb/s, the module will reclock the signal at the
determined bit rate and feed this signal to both the electrical BNC and the
fiber optic outputs. With input reporting enabled, the input signal will be
reported as Present.
If no input signal or a signal other than 270Mb/s is detected by the module,
the output of the reclocker will be muted and the outputs will be static
(muted). With input reporting enabled, the signal input will be reported as
Not Present.
Fixed 1.5G/Mute Mode
In this mode, the electrical inputs are equalized and fed to the reclocker. If
the bit rate is analyzed as 1.5Gb/s, the module will reclock the signal at the
determined bit rate and feed this signal to both the electrical BNC and the
fiber optic outputs. With input reporting enabled, the input signal will be
reported as Present.
If no input signal or a signal other than 1.5Gb/s is detected by the module,
the output of the reclocker will be muted and the outputs will be static
(muted). With input reporting enabled, the signal input will be reported as
Not Present.
Auto/Bypass Mode
In this mode, the electrical inputs are equalized and fed to the reclocker.
The bit rate is analyzed by the module. If the bit rate is analyzed as
270Mb/s, 1.5Gb/s or any bit rate above 19Mb/s, the module will reclock
the signal at the determined bit rate and feed this signal to the both the elec-
trical BNC and the fiber optic outputs. With input reporting enabled, the
input signal will be reported as Present.
If a bit rate other than 270Mb/s or 1.5Gb/s is detected by the module or no
input signal is detected, reclocking will not be performed and the signal
will be automatically bypassed to the outputs. With input reporting
enabled, the input signal will be reported as Not Monitored.
Fixed Bypass Mode
In this mode, the electrical inputs are equalized and the reclocker is
bypassed regardless of the electrical input data. The bypassed signal is fed
to both electrical BNC and the fiber optic outputs.
Note In this mode only, HD signals will be invalid on the electrical outputs due to
an SD slew rate applied to the drivers on the electrical BNCs.
