The Newtec AZ210 1+1 Modulator Redundancy Switch product provides
a versatile 1+1 protection scheme for satellite modulators. The
AZ210 is easy to operate and switches simultaneously the input
data signals and output IF/RF signals.
The switching between the main modulator and the redundant
modulator can be done automatically through alarm contacts,
manually through the front panel or the dedicated web interface,
or remotely via a monitoring and control system.
When the automatic mode is activated, the AZ210 monitors
the alarm contacts of the two modulators through cable
connections. When an alarm is detected, the input and output
switches are toggled, effectively rerouting the input and output
signals to the redundant modulator. The fast switching ensures a
minimal service interruption.
In its default configuration, the AZ210 switches an output IF
(75 ohms) signal. A wide range of input and output switching
options makes the AZ210 compatible with almost any signal
used in satellite communications. The range of options includes
ASI, optical, G.703, SDH, HSSI and Gigabit Ethernet input
switches, as well as IF, L-band and RF output switches.
The AZ210 is easy to operate and monitor. All control and
monitoring parameters are available locally on the front panel
and remotely through a web interface. It is also possible to
control or monitor the AZ210 via RMCP or SNMP.
