SDH, SONET and PDH Measurement

Measurement at Bit Rates from 1.5 Mbit/s to 10 Gbit/s

A mapping route to a bit rate of up to 10 Gbit/s can be set.

The MP1570A mainly supports SDH, SONET, Japanese

mapping, PDH of the European system and DSn of the North

American system for digital communications. For concatenation

mapping, a route can be set from STM-1c up to STM-64c.

Furthermore, the MP1570A supports a combination of channels.

For example, 64 channels of VC4c, 16 channels of VC4-4c, and

four channels of VC4-16c.(See figure 1 in page 20)
