Applications

2.1 OC-12c/STM-4c
The "OC-12c/STM-4c" options expand the applications of the virtual instruments (VI) of the
ANT-20 to include the following signal structures:
• STS-12c SPE
• STS-12v SPE
• VC-4-4c
• VC-4-4v
These signals have a payload bit rate of 599.040 Mbit/s.

The "Signal Structure" VI can be used to set the appropriate mapping for concatenated
containers for the transmitter (Tx) and receiver (Rx).
The following VIs can be used for tests after the settings are made:
• Performance Analyzer
• Anomaly/Defect Analyzer
• Anomaly/Defect Insertion
• Overhead Analyzer
• Overhead Generator
• Pointer Analyzer
• Pointer Generator
• Jitter Generator/Analyzer
• ATM Signal Structure
• ATM Traffic Analyzer
• ATM Background Load Generator
The "OC-12c/STM-4c ERROR TEST (BULK)" and "OC-12c/STM-4c ATM TESTING" options
provide test functions for contiguous concatenation mapping.
With the "OC-12c/STM-4c ERROR TEST (BULK)" option, a bulk signal is mapped into the
concatenated containers. With the "OC-12c/STM-4c ATM TESTING" option, cells are mapped
into the containers.
