Description of Model
The main features of a dual standard (SDH/SONET) instrument are as follows:
• Multi-rate BER and jitter testing (opt 200) from 64 kb/s to 2.5 Gb/s (STM-16/OC-48).
• Concatenated payloads at all synchronous rates up to 2.5 Gb/s
• Full PDH/T-carrier testing.
• Direct measurement of protection switching time.
• Powerful thru-mode testing for SDH/SONET ring turn-up.
• Comprehensive SDH/SONET overhead testing.
• Packet over SONET/SDH (POS) and ATM payloads up to 2.5 Gb/s.
• Fast access to key measurement tasks via Smart Test.
• Optical power and line frequency measurements.
• J0 section trace for DWDM testing
• J1 and J2 path trace for network path testing
• Optional integrated graphical printer
• Line frequency offset
• Transmit and Receive can be independently configured.
