Basic Test Procedures This section gives examples of how to set up and use the CTS850 SDH/PDH Test Set for several common telecommunication network applications: H Network continuity checking H Transmission signal quality testing H Fault tolerance testing H Performance monitoring H Jitter and wander testing H Video timing quality testing Setting Up the CTS850 This section presents setup instructions for the CTS850 in tables. Perform the steps reading from left to right in the table (see example below). The word none in a cell indicates that no action is required. Press Menu Select Menu Highlight Button Page Parameter Select Choice Begin here with Step 2 Step 3 Step 4 Step 1 Step 5 Step 6 Step 7 Step 8, CTS850 Setup is complete Menu buttons are located on the instrument front panel. Select menu pages with the buttons below the display. Use the knob to highlight a parameter; then use the buttons at the right to select a choice. Many setups require several iterations of highlighting parameters and selecting choices. Some setups may require more than one menu button or menu page selection as well. CTS850 SDH/PDH Test Set User Manual 3 1 Basic Test Procedures The first step in each application setup initializes the CTS850 to a known state. Network Continuity Checking With the AUTOSCAN feature of the CTS850, it is easy to make a quick continuity check. The continuity check verifies that a SDH network element (NE), or portion of the network, is correctly set up and provisioned and that the signal passes through intact. In this example, the CTS850 transmits an STM-1E signal into an NE. Then the CTS850 receives the output from the NE and verifies that the AU-4, including its payload patterns, is intact. 1. Connect the CTS850 to the NE as shown in Figure 3 1.
