Setting PDH Receive Parameters This section describes how to manually set the receive rate, receive level, framing, and test pattern for PDH signals. Pressing AUTOSCAN sets the receive parameters automatically based on the received signal. Steps for Setting Parameters The sequence of steps for setting receive parameters varies with signal to be received. Figure 3 60 shows the sequence of steps required to set the receive parameters for PDH signals (for example, 2 Mb/s).

This menu has all of the setup items required to configure a 64k or N x 64k signal, along with duplicates of the framing selections and test pattern choices. Figure 3 62:64k Rx SETTINGS from RECEIVE SETTINGS menu Table 3 22:64k Rx SETTINGS Choices 64k RX Settings Choices Framing Selects the framing for the underlying 2 Mb/s signal. Choices are 2Mb/s PCM30, PCM31, PCM30CRC, and PCM31CRC. Configuration Selects the 64k configuration. The menu choices are 1x64k, Nx64k Contiguous. Number of Time- If the configuration is N x 64 k, this selects the number of slots contiguous channels (N) that make up the signal. This choice will not display for a 64k configuration. 3 148 CTS850 SDH/PDH Test Set User Manual Setting PDH Receive Parameters Table 3 22:64k Rx SETTINGS Choices (Cont.) 64k RX Settings Choices Starting Timeslot This selects the starting (or only) timeslot.
