The RABA CoreFoundry E1 Processor family of products includes E1 processors for multiplexing analog signals into a standard E1 output, or for demultiplexing all voice channels from a standard E1 input.

The rear panel E1 inputs and outputs are Trompeter BJ770 twinax connectors. A suitable cable mating connector is a Trompeter PL75-9.

All analog audio inputs and outputs are on RJ-45 connectors, with four audio pairs per RJ-45 connector. Any standard CAT-5E cable can be used to interface to the audio I/O ports. A 1U breakout panel is available to convert the CAT-5E to standard, unbalanced BNC connectors. Contact RABA CoreFoundry if different connector types are desired (such as bantam), or if balanced operation is desired.

Multiplexer units have an external 2.048 MHz clock input on the RJ-45 connector block. This clock can be selected by the operator to be used as the E1 multiplexer clock. An internal 2.048 MHz clock is also available for this purpose.

On all products, a front panel User Interface is used to setup and monitor operation. The User Interface is comprised of an LCD display with two ‘menu select’ buttons to the left of the display, and four ‘arrow’ buttons to the right of the display. The menu select buttons are used to scroll through the various setup and monitoring menus, while the arrow buttons to the right of the display allow navigation within a displayed menu.

A front panel speaker can be used to monitor a selected timeslot from an E1 input or output. A headphone jack is also provided, and plugging in a headphone cord will disable the audio to the speaker. An associated volume control sets the volume for the speaker or headphone.
