4. Wander and jitter measurement options
Choose one option (if required). If you need PDH jitter
measurement then also order PDH/DSn interface option (section 1).
● PDH (tributary) jitter and wander measurement: 2, 8, 34, 140 Mb/s, with HP1, HP2 and............... UHN 1
LP filters to ITU-T O.171 plus 2 Mb/s wander and estimated frame slip measurement.
● STM-1e line jitter and PDH (tributary) jitter; rms, peak-to-peak, auto jitter transfer ...................... A3L 2
and wander measurement: 155 Mb/s electrical interface with HP1, HP2, LP and 12 kHz HP
filters to ITU-T O.171/G.825.
● STM-1o/STM-1e, plus all the capability of option A3L.............................................................................. A3V 2
● STM-4o/STM-1o/STM-1e, plus all the capability of option A3L. ............................................................ A3N 2
† 8 and 140 Mb/s jitter measurement requires a PDH option with 8 and 140 Mb/s
interface to be fitted

5. ATM services layer test options
Choose one option (if required). As these modules use the interfacing provided by a
PDH/DSn and ATM test option, must also order ATM option UKN or UKZ (section 1).
● Provides ATM and AAL capabilities including Channel View, rate history,.......................................0YK† 1
graphical CDV, benchmark traffic.
● As per option 0YK (but occupying two slots) plus native Ethernet LAN .......................................... USL† 2
connectivity tests.
† Option 0YK and USL do not support options A3R and 120 at present.
Please refer to module interworking section (pages 6 and 7).

6. PDH binary interfaces options
Choose one option (if required). Must also order a PDH and ATM test option (section 1).
(Option UH3 does not support options UKZ, 0YK or USL at present.)
● PDH NRZ interfaces: Adds binary Tx clock and data, binary Rx clock and data, ........................... UH3† 1
plus external clock input.
● PDH synthesized BER testing bundle : Includes UH3 (binary clock and data), ................................ 200 3
UKK (unstructured BER module) and HP 8647A synthesizer.
† Option UH3 does not support options UKZ, 0YK and USL at present.
Please refer to module interworking section (pages 6 and 7).
