General Description

The AETHER-2.5GS is a single-chip implementation of an STS-48/STM-16 LTE/MSTE, with additional capabilities to support grooming, configuration and performance monitoring functions. This “single device solution” complies with SONET/SDH standards and specifications, including ANSI T1.105, Bellcore GR-253-CORE, ITU-T G.707 and G.783. Figure 3 shows a simplified architecture of AETHER-2.5GS.
