Actus G300 is a flexible multi-service access switch with two available optional slots which fit for various types of TDM and Ethernet multi-service line cards. The User Service modules are available for STM-1/OC-3, E1/T1 and Ethernet services. The G300 can locate as a small scale aggregation site for the wireless backhaul network. The compact design of G300 1U height supports very low power consumption and saves space. The G300 offers a full scale of carrier class high availability with G.8032 ERP (Ethernet Ring Protection). The ERP function provides SONET level of protection within 50m seconds. In addition, the G300 offers carrier grade OAM features, such as 802.3ah, 802.1ag and Y.1731.

In conjunction with G200, the G300 provides end-to-end service for the 2G/3G and 4G wireless backhaul network.
