Overview

Model 7143 RS232 Remotely Controllable Three-Channel Normal/Bypass Switch, E1 RJ48 Interface  

The PathWay® 7143 Three-Channel RJ48 Normal/Bypass Switch supports connection into a network (NORMAL) or disconnection from a network (BYPASS) of an “in-series” type device or terminal. Each switch channel is able to be switched singly or as a group.  The Model 7143 is enclosed in a 1U, full rack size, all metal black chassis designed to provide EMI/RFI shielding and fit in a standard 19” rack. The switch may be controlled locally by manually operating the front panel pushbuttons, or remotely from the DB9 Serial Remote port located on the rear panel.  The front panel LED display indicates if the switch is in Normal or Bypass Mode. Each channel monitors data activity of port “2” and port “3”. The Model 7143 can be set to different modes of operation to respond to data presence and data failure.

  • Allows New Equipment to be Added-To or Bypassed From E1 Data Links.

  • Ideal for inserting or removing devices that are concatenated, linked together in a chain or series.

HOW THE MODEL 7143 NORMAL/BYPASS E1 RJ48 SWITCHER WORKS:

The PathWay® 7143 Three-Channel RJ48 Normal/Bypass Switch is designed to seamlessly insert or remove in-line devices from active E1 networks without disrupting service. In Normal mode, the switch routes traffic through connected equipment; in Bypass mode, it automatically or manually routes traffic around the device to maintain uninterrupted network operation. Each of the three channels can be controlled independently or switched simultaneously as a group, providing flexible operation for multi-circuit environments. The Model 7143 is housed in a rugged 1U, full-rack, all-metal chassis that fits standard 19-inch racks and provides effective EMI/RFI shielding for use in demanding telecom and industrial environments. Switching can be performed locally via front-panel pushbuttons or remotely through the rear-panel DB9 serial control port, allowing integration into centralized monitoring or control systems. Front-panel LEDs clearly indicate Normal or Bypass status for each channel, providing instant visual confirmation. The Model 7143 continuously monitors data activity on ports 2 and 3 and supports multiple operating modes that can automatically respond to data presence or data failure, ensuring network resilience and protecting critical E1 circuits.

FEATURES:

  • Model 7143 is a 3-Channel unit.
  • The switch ports are transparent to all data.
  • All (8) pins of the RJ48 interface are switched via break-before-make electromechanical relays.
  • Normal Position connects 1 to 2, and connects 4 to 3, thereby inserting concatenated device into the network.
  • Bypass Position connects 1 to 4, isolates 2 and 3, thereby removing concatenated device from the network.
  • Simultaneous control of channels.
  • Independent control of channels.
  • When power is lost, unit reverts to the Bypass position.
  • In Manual mode, when power is restored, the unit stays in Bypass position.
  • In Auto mode, when power is restored, the unit will automatically switch to the Normal position if signal is present on Ports 2 and 3 of a given channel.
  • Remote RS232 ASCII commands that allow the user to control switch position, lockout front panel operations, obtain switch status, as well as, query firmware version number, query serial number and enable/disable autosend of switch positions.
  • Remote RS232 commands that also allow Set Filter Default value, unlock/lock designated channel, Auto Mode, Manual Mode, and gang commands.
  • A 6-Channel unit is also available (Model 7146, Cat 307146).
  • A 1-Channel unit is also available (Model 7141, Cat 307141).

SPECIFICATIONS:

  • PORT CONNECTORS: (12) RJ48 female connectors (Four connectors labeled 1, 2, 3, 4, for each of the three channels).
  • FRONT PANEL CONTROLS: (3) Manual pushbuttons allow local switching.
  • DISPLAY: (6) Front panel LED's display switch position and power status.
  • REMOTE: (1) DB9 (F) connector on rear panel accepts ASCII RS232 Serial Data for Remote Control operation.
  • POWER: "Wide Range" CE, RoHS, and UL listed table mount power module (Cat No. 517277) 100VAC/240VAC, 50Hz/60Hz. Has IEC 60320 C14 inlet.  Ideal for international applications.
  • DIMENSIONS: Rackmount 19.0" W x 1.75" H x 8.2" D. (48.3 x 4.5 x 21.9 cm)
  • WEIGHT: Approximately 5.5 lbs (3.5 kg) 

While many networks are transitioning to IP, E1 links remain widely deployed in mission-critical environments such as telecommunications, public safety, utilities, and transportation systems. These circuits often operate for decades and require dependable hardware for monitoring, maintenance, and fault isolation. The Model 7143 enables operators to insert or bypass in-line equipment on live E1 circuits without interrupting service, preserving uptime while supporting legacy systems that remain operational today.

NORMAL/BYPASS E1 INTERFACE APPLICATION:  Allows New Equipment to be Added-To or Bypassed From E1 Data Links along with an ASCII RS232 DB9 Remote Control.

The application drawing shows a device inserted into the network and a device removed from the network. It also shows the DB9 Remote port for ASCII RS232 commands for Remote Control Operation.
