Multiple PDH Transmitter Outputs (Options UHC,
[US6])
NOTE A PDH Option must be fitted for this option to operate - see Appendix B.
Specifications
Pulse Shape: As per ITU Rec. G.703
Additional Outputs Delay
NOTE 704 kb/s is only valid when Option UKK, [USB] is fitted.
Description
This test verifies that the 3 additional PDH transmitter outputs meet ITU pulse shape
and level specifications for all rates. Each PDH Signal Out Port is connected to a
Digitizing Oscilloscope terminated in 75Ω and the waveform is checked for
required amplitude and duty cycle at the nominal mid-points.
Pulse Amplitude:
704 kb/s 2.37V ±10%
2 Mb/s 2.37V ±10%
8 Mb/s 2.37V ±10%
34 Mb/s 1.00V ±10%
140 Mb/s 0.50V ±10%
704 kb/s, 2, 8 and 34 Mb/s Signal Out 2 4 bits
704 kb/s, 2, 8 and 34 Mb/s Signal Out 3 8 bits
704 kb/s, 2, 8 and 34 Mb/s Signal Out 4 12 bits
140 Mb/s Signal Out 2, 3, 4 No delay
