12. Pulse amplitude measured at the output of the transformer across a 75
13. Pulse amplitude measured at the output of the transformer across a 120
14. Pulse amplitude measured at the output of the transformer across a 100
15. Pulse amplitude measured at the DSX-1 Cross-Connect for all line length settings from
16. Input signal to RTIP/RRING is jitter free. Values will reduce slightly if jitter free clock is input to TCLK.
17. Not production tested. Parameters guaranteed by design and characterization.
