Structured Data features
Transmitter receiver
instrument generates receives X.50 structured signals kbit/s. Input output signals either channels within Mbit/s systems kbit/s dedicated V.11 interfaces. transmitter receiver operate independently.
Line codes
Line codes available kbit/s are: NRZ, codirectional, contradirectional, 100%, biphase mark space.
Test patterns
instrument receive various test patterns, extracted from X.50 structured channel channel signal, reiterated data signal. Test patterns generated transmitter insertion into same channels receiver. Test patterns include pseudo random sequences, fixed programmable patterns AIS. structured data signal containing test pattern also inserted into channel signal extracted from received signal. pattern also selected fill unused channels X.50 structured generated signal
Receiver
Test measurements
receiver measure simultaneously parameters associated with Pattern errors Framing errors. These include number errors error ratio. More detailed analysis made these error types. These include histogram displaying error distribution over hours with indicators loss synchronisation power, current error ratio error performance measurements G.821.
Signal inputs
receiver receive balanced V.11 balanced signals. received rate measured displayed.

Error injection
errors injected into Pattern bits, Framing bits Envelope bits user specified bits. Errors injected singly keypress single shot automatically rate. Errors also injected into live traffic channels within structured data system using Drop Insert mode.
