1.Overview

ZCC-1300 is a STM-1 SDH terminal multiplexer that transports Gigabit Ethernet over SDH networks. It provides 4 Gigabit Ethernet interfaces and 2 STM-1 interfaces, supports 1+1 path protection and 2+0 mode. In 1+1 mode, the 4 Gigabit Ethernet interfaces share one VCG and the bandwidth is one VC4 (139Mb/s). In 2+0 mode, the 4 Gigabit Ethernet interfaces share two VCG channels and the bandwidth is two VC4. Therefore, By GFP and EoSDH technology, ZCC-1300 can realize two 139Mb/s Ethernet traffic transmission over STM-1 line.
