1.Overview

ZCC-100 is a Network Termination Unit connecting Fast Ethernet LANs over single E1 circuit. The device enables service providers to supply high-capacity Ethernet services to remote locations, and transparent connection of corporate LANs over existing E1 lines. The device can be used in point-to-point or in point-to-multipoint topology work together with Central unit ZCC-1200N/ZCC-1500. The device uses HDLC/GFP encapsulation to map the Ethernet traffic over E1.Typical applications include:

• Ethernet private Line / LAN services.
• IP DSLAMs, Cellular IP, and WiMAX base station back-hauling.
• Inter-office or Enterprise LAN connectivity.
