RB008 Dual-VCG channel Gigabit Ethernet Converter (RB008)

Overview

RB008 is a dual - VCG channel Gigabit Ethernet Converter, provides 4 gigabit Ethernet interfaces (3 copper and 1 fiber Ethernet interfaces) compliant with IEEE 802.3 series standard and 2 STM-1 optical interfaces, supports 1+1 optical path protection and 2+0 mode. In 1+1 mode, the 4 Etherent interfaces share one VCG and the bandwidth is one VC4 (139Mb/s). In 2+0 mode, the 4 Ethernet interfaces share two VCG channels and the bandwidth is two VC4. Therefore, By GFP and EoS technology, RB008 can realize two 139Mb/s Ethernet traffic transmission over STM-1 optial line.

The ingress port mirroring function can be available Only when both the broadcast strom filtering function and ingress port rate control function are closed.

Application

RB008 supports point-to-point application. In 1+1 mode, the 4 Etherent interfaces share one VCG and the bandwidth is one VC4 (139Mb/s). In 2+0 mode, the 4 Ethernet interfaces share two VCG channels and the bandwidth is two VC4. Refer to section 5.3 for more.
