System Modules

If line B is the active line and you lock the RSM on line B, no switching takes place. The communication is locked on line B. Any automatic switching to the backup line (line A) is stopped.

If line B is the active line and you lock the RSM to line A, the RSM checks the accessibility of line A. If line A is functional, the RSM switches the communication to line A and holds the communication on this line. Any automatic switching to the backup line (line B) is stopped. If line A is broken, the RSM cannot be locked on line A.

At any time, the RSM can be switched from lock mode to automatic mode.

If neither line A nor line B is connected to the RSM or both lines are broken, the red on LED blinks. Also, line A and line B LEDs are red as a visual signal to check for disconnected lines.

The push buttons below the LEDs allow you to switch between automatic mode and lock mode. Lock mode can be enabled for either line A or line B. If the lock mode for one line is activated, the communication cannot be automatically switched to the other line.

Lock mode can be enabled either for an active line or for a backup line. If the active line is locked, the communication cannot be switched to the backup line. If lock mode is enabled for a current backup line by pressing the respective button, the RSM checks the availability of the backup line and (if the line is in working order) switches the communication to it, so that it becomes the active line and locks it. Now, automatic switching to the backup line is impossible.

If the red on LED blinks and one of the A and B LEDs is red while the other one is flashing red, this indicates two possible situations: neither line A nor line B are connected to the RSM or both lines are broken. In this situation, the lock mode can be activated once for testing purposes.

TDM4E Wavelength Channel Modules

The Cisco Metro 1500 series system can be equipped with an optional time-division multiplexing 4 x ESCON (TDM4E) wavelength channel module. The TDM4E uses TDM technology to provide a transmission capacity four times higher than conventional WCMs. TDM technology allows you to combine 4

200 MB ESCON channels into one WDM channel, making optimal use of the available fiber bandwidth.
