MEGSM-155CP Chassis STM-1 Equipment

Overview

MEGSM-155CP is a STM-1 optical transmission system, which technical performance complies with ITU-T standards; it has interoperability with popular SDH/MSTP products of other vendors. It provides six 155.52Mb/s optical interfaces, 231 E1 add/drop multiplexing, and both high-order and low-order signals can be non-blocking cross-connected.
It possesses complete network elements timing function and strongly non-blocked cross connection. It can also supports point to point, chain or ring networks, with Sub Network Connection Protection (SNCP).
