Port Designs ( NM-1T3/E3 ) (NM-1T3/E3=) Expansion Module

This flexible network module allows the customer to switch between T3 and E3 applications with a single Cisco IOS command. The demand for increased bandwidth has led to growth in clear-channel T3/E3 deployment. The module provides an integrated line interface unit (LIU) DSU that allows T3 or E3 lines to be directly terminated on a Cisco router, eliminating the need for external DSU equipment.
