The 2300R is a state-of-the-art, rack mount, multi-drop data mo-
dem designed to provide the user with trouble-free data transmis-
sion in both self-healing ring and Multidrop string configurations.
This 2-slot card modem has self-diagnostic capabilities that can
be monitored on a computer via the front-panel mounted RS-232
or USB ports. A front panel mounted RS-485 port is provided for
interconnecting the network diagnostics on two or more master
modems. The PC based Network Management system incorpo-
rates real time system diagnostics for monitoring various net-
work and modem parameters including, but not limited to: Optical
connectivity, Optical budgets, Power supply voltages, Individual
modem operating parameters, alarms & alarm history and network
BER. A GUI network representation monitors the fiber connectiv-
ity for other modems that are on the ring / string network. If a fiber
is broken an alarm activates, giving the user a visual representa-
tion of a broken fiber and its location in the network. Both primary
and redundant fiber rings are simultaneously monitored by the
network diagnostics. The 2300R product family combines so-
phisticated self-healing ring topology and computer based diag-
nostics to provide your network with round the clock monitoring.
The self-healing ring automatically detects faults and reroutes
communications on the ring to keep your network operational while
the built in diagnostics reduces the time required by technicians to
analyze, locate and repair the fault.
The modems can be installed in a string or counter-rotating,
fault-tolerant ring network. The switch selectable feature allows
each modem to be set as a Master (primary or secondary) or
Slave. The Master modems are connected to the PC via the
RS-232 or USB ports. This modem interfaces with both additional
PX-2300R modems as well as Meridian’s PX-2300M, surface-
mount Multidrop modem. The 2300R can be installed in all of
Meridian’s card chassis, desk chassis and 19” racking frames.
These systems can be made a standalone system by using the
SR-1000/S, 2 slot desk / wall mount chassis (87VAC-264VAC)
