Original Press Release:

A Great Solultion for Fallback Network Applications, The Model 4421 Cat5 A/B Switch

Electro Standards Laboratories (ESL), Cranston, RI, has just introduced the Model 4421 Cat5 RJ45 Interface A/B Switch for fallback network applications. The A, B, and COMMON ports are RJ45. The switch connects a workstation or device between two other devices or networks. The internal circuitry insures isolation between the A and B devices/networks. A front panel button changes the switch position eliminating the need to plug and unplug patchcords thus minimizing connector wear. Switch position status is displayed on the front panel LEDs.

The unit also includes an RS232 serial security enhanced Supervisory Remote Port. Upon proper authentication, a terminal or computer in terminal mode connected to this port can communicate with the unit, determine its status, change the switch position as desired, and/or lockout front panel switching capability. A modem can also be connected to this port for remote access to the switch. Access to the Supervisory Remote Port feature is password protected. Optional graphical
user interface (GUI) software is available for use with a computer running Windows 95/98/NT/Me/2000/XP.
