Electrodynamic Seismic Test System

Telecommunications companies that sell to RBOC’s (Regional Bell Operating Companies) are required to test their product(s) to a set of standards written by Telcordia* (formerly Bellcore). A large portion of this standard includes vibration testing, and can be found in the GR-63-CORE specification. Unholtz-Dickie offers a complete line of shaker systems specifically designed for testing telecommunications equipment to these standards.

The vibration profiles in GR-63-CORE include three specific vibration test methods. Each method requires a shaker system with unique performance design features. Click on the test method listed below for more information and the recommended UD Vibration System.

Office Vibration
Transportation Vibration
