Applications
SONET analysis
The FST-2310 can be used to verify end-to-end network performance via BER
testing at SONET rates up to OC-48 as well as to analyze SONET network
performance under abnormal conditions by simulating pointer justifications and
inserting error and alarm conditions. Users can also manipulate and analyze all
applicable SONET overhead bytes to verify network element performance (for
example, pointer adjustments, alarms, DCC bytes, SONET sync messages, and
K1/K2 bytes) (figure 4).
Qualify the performance of SONET networks quickly and easily with the FST-
2310’s intuitive GUI. By supporting various payload mappings, the FST-2310
enables testing and verification of individual payloads inside an OC-n signal
(DS1, DS3, multiplexed DS3, VT1.5, OC-n subrates).
Additional functionality includes the ability to drop and insert all mappings (OC-
12/3/DS3/DS1) from an OC-48 signal. Monitor individual DS1, DS3, or OC-n
subrate payloads within SONET signals for analysis, and verify signal power and
signal frequency of a received signal. Technicians can also name and identify trace
messages and payloads by using the FST-2310’s user-configurable path trace
messages.
SDH analysis
The SDH functionality on the FST-2310 enables performance verification of SDH
networks at the STM-16, STM-4 and STM-1 rates. The FST-2310 supports
performance testing of individual payloads inside an STM-n signal (STM-16c,
STM-4c, STM-1c). Ensure proper network operation with error/alarm analysis as
well as the manipulation/analysis of all applicable SDH overhead bytes. Correct
network timing can be monitored through pointer adjustment measurements.
