The NetClock 9483 also includes backwards-compatibility support with all previous generation
NetClock products; thus providing a bridge from legacy devices and equipment to network-
based systems.
The NetClock 9483 series is a truly flexible Time Server/Master Clock, which in addition to
providing highly accurate network time synchronization, also supports a variety of timecodes
(including all NENA formats) and signals to synchronize specific devices. The built-in network
port can be supplemented to include 3 additional Gigabit Ethernet (10/100/1000Base-T) ports
for synchronizing isolated networks, or for restricting administration to a specific management
network. Precise 10- MHz and 1- Pulse- per- second (1PPS) signals are standard features, and
additional optional features include support for T1/E1 signals are available for synchronizing
telecom systems and equipment, and Precision Timing Protocol (PTP) I/O support.
The unit is housed in a 19” rack unit chassis and offers an integrated power supply. DC power
is available as back-up to AC power, or as the primary input power source.
Note: All features described are not available on all NetClock 9400 Series vari

ther management and configuration can be performed via NetClock’s Web-based user inter
