1.Overview

ZCC-1200N is a Gigabit Ethernet over TDM aggregation gateway that interconnects packet networks via PDH access. It provides three gigabit Ethernet interfaces and 24 E1s interfaces. ZCC-1200N typically deployed at a central location, It aggregates user Ethernet traffic received from remote devices (such as ZCC-100, ZCC-101, ZCC-110, ZCC-110L), thus completing a full access solution from the service provider’s central site to the customer premises. ZCC-1200N can be used in the traffic convergent network, supports point-to-multipoint application. Other typical applications include:

• IP DSLAM and IP base station traffic backhauling.
• WiMAX BTS traffic backhauling.
• Ethernet private line/LAN services.
• Backhauling of network management traffic.
• Aggregation of Ethernet traffic over PDH wireless links.

4.Application

In the application, the Ethernet service of each remote user can be carried by different VCG channels, each VCG can be assigned to 1~16 E1 flexibility and the total bandwidth of the 16 VCG channels cannot be exceeds 24E1s..

As shown in Figure1-4-1, with EoPDH and VLAN technology, the remote Ethernet service can be transmitted and converged into the service center (Switch) by ZCC-1200N (point-to-multipoint); ZCC-1200N support OAM management frame-based E1 channel, by OAM frame, all remote devices can be configured and monitored.
