    2 FEATURES AND BENEFITS Modularity The DSX-3 (DSX-4U-24) Rear Cross-Connect System is modular for easy expansion at the user’s site, and may provide any number of bi-directional cross-connects in multiples of 120 (up to 240 equipment terminations) per 2.13 meter (7 foot) bay. This allows for installation of a minimal system configuration to meet the immediate needs of a site, and then expanding it as necessary by adding individual DSX-4U circuit modules.
