Setting SDH Transmit Parameters This section describes how to set the transmit rate, specify the AU under test, set the payload mapping and content, and set the overhead bytes for SDH signals. The CTS850 SDH/PDH Test Set contains independent transmitter and receiver modules. One set of parameters controls the transmitter module and another set controls the receiver module. You can set the parameters that control the transmitter independently or you can choose to link the parameters to the receiver settings. Figure 3 26:Transmit Settings Menu CTS850 SDH/PDH Test Set User Manual 3 71 Setting SDH Transmit Parameters Steps for Setting Parameters The sequence of steps for setting transmit parameters varies with the type of signal to be transmitted. The figures that follow show the sequence of steps required to set the transmit parameters of an SDH signal without a mapped PDH signal and an SDH signal with a mapped PDH signal. See the next section for details on setting PDH signal parameters (for example 2 Mb/s).

H Select 2 Mb/s, 34 Mb/s, 140Mb/s to transmit a PDH signal. See the next section for details on setting PDH signal parameters. H If your CTS 850 test set supports the 45 Mb/s option, there is also a 45 Mb/s signal available for selection. NOTE. Even though there are output connectors for both SDH and PDH signals
