DESCRIPTION:
The 2300M is a state of the art self healing, counter rotating multi-drop data
modem designed to provide the user with trouble free data transmission in
both ring and string configurations. In addition to being equipped with all of the
expected features, local and remote diagnostic capabilities are included in
each modem. The user-friendly diagnostics menu can be accessed via two
small buttons located on the front panel. These buttons are used for scrolling
through the menu functions. The status of any other modem can be viewed
on the SpectraSmart
TM
System. Field technicians can perform local and
remote diagnostics without the aid of a PC. Parameters viewable on the
LCD display are internal modem temperature, power supply voltages, opti-
cal ring status, location of fiber breaks, unit failures and many other critical
parameters. If a parameter is exceeded, a flashing light and audible alarm
are activated at all modems. Both primary and secondary rings are moni-
tored simultaneously by the network diagnostics. If the primary ring is bro-
ken, the LCD will display the address of the modems on each side of the
break providing quick trouble free identification. In the event of a fault, cus-
tomer data will automatically be transferred to the secondary ring.
SpectraSmart
TM
PC, a windows based GUI driven network management
system can be connected to the Master Primary and Master secondary
modems via an RS-232 or RS-485 cable. When a PC is used, the GUI will
display the entire Network and a change of color at the trouble location. The
SpectraSmart
TM
software works in conjunction with the LCD display located
on the individual modems. When operating normally the Primary Master
modem monitors quantity and numerical sequence of slave modems on the
ring and each modem stores the last five alarms, which can be displayed on
the local LCD display. The 2300M family combines sophisticated self-heal-
ing ring topology and computer based local and remote diagnostics to pro-
vide your network with round the clock monitoring. The self-healing ring
immediately detects faults and reroutes communications to keep your net-
work operational while the built in diagnostics reduces the time required by
technicians to analyze, locate and repair the fault.
CONFIGURATIONS:
The modems can be installed as a string or counter rotating fault tolerant
rings. The switch selectable feature allows each modem to be set as a Mas-
ter Primary, Master Secondary or a Slave. The Master Primary and Master
Secondary modems are connected to the PC by an RS-232 or RS-485
cable and provide redundancy if Master Primary or the optical ring is bro-
ken.
