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 SpectraSmartTM 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, optical 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 monitored simultaneously by the network diagnostics. If the primary ring is broken, 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, customer data will automatically be transferred to the secondary ring. SpectraSmartTM 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 SpectraSmartTM 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-healing ring topology and computer based local and remote diagnostics to provide your network with round the clock monitoring. The self-healing ring immediately detects faults and reroutes communications to keep your network 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 Master 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 broken.
