SONET/SDH

Overview

Aliathon’s SONET/SDH products enable high bandwidth, deeply channelized solutions that support all SONET/SDH line rates and mapping paths, including full Higher Order and Lower Order Path Processing and PDH Tributary mapping and framing.

The cores support multiple asynchronous line interfaces, and are available in channelized and non-channelized variants.  Fine-grained flexibility allows support for all types of client signal, from traditional TDM and PDH to ATM, GFP and POS interfaces.
