New Family of Normal/Bypass Switches

Press Release

New Family of Normal/Bypass Switches

• Allows new equipment to be added to or bypassed from E1 Data Links
• Available as 1, 3 or 6-channel units.

Electro Standards Laboratories, Cranston, RI, has just announced its new family of Normal/Bypass Switches, E1 Interface with Remote Control. This switch allows new equipment to be added or bypassed from E1 data links.

The switches are packaged in a rackmount enclosure. Front-panel indicators and pushbutton controls allow the operator to observe switch status, override the remote or automatic control, and to operate the switch manually. The rear panel has RJ48 connectors for cable connection to the E1 link and the new equipment. A DB9 Remote Control connector on the rear panel has a serial data interface and allows the remote operation and monitoring of the switch. The switch is programmed so that detection of power loss or data activity loss returns the switch position to Bypass mode. Power is provided by an external plug-in supply that allows operation at 90-230 Volts AC, 50/60 Hz.

The Model 7141 has one Normal/Bypass switch function, Model 7143 had three, and Model 7146 has six. For more information, call Electro Standards Laboratories at 401-943-1164.
