Configuring SDH on 1-Port OC-192/STM-64 or
8-Port OC-3/12/48/STM-1/-4/-16 Module
SDH is a standard that defines optical signals as well as a synchronous frame structure for multiplexed digital
traffic. It is is used in Europe by the International Telecommunication Union Telecommunication
Standardization Sector (ITU-T). The SDH equipment is used everywhere except North America.
SONET equipment is generally used in North America. Previously, 4-Port OC3 STM1 or 1-Port OC12 STM4
Module did not support all possible combinations of the SDH hierarchy.
SDH is supported on 1-Port OC-192/STM-64 or 8-Port OC-3/12/48/STM-1/-4/-16 Module along with
SONET. The IM supports the entire SDH hierarchy (except VC-2/C-2).
