Connect the incoming DS3 (the DS3 from which the DS1s are dropped) to the DS3 ABNCs.2. Connect the outgoing DS3 to the DS3 B BNCs.3. Connect the DS1s using the amphenol connectors on the rear panel.For more information, refer to “Rear Chassis Connections” on page 4-7.NOTEThe default mapping of the 3/1 cross-connect is for all the DS1s topass straight through from one DS3 to the other. No DS1s aredropped to the DSX-1 ports or the expansion slots. If needed, re-establish the default mapping through selecting the Restore Map toFactory Default option in the “Cross-Connect Menu” on page 6-35.Starting from the default mapping, use the Quick Setup menu to drop the DS1s. Select eachDS1 port (1–16) to which a DS1 needs to be dropped from the incoming DS3. For each DS1port, select the DS1 in DS3 A to be dropped to that DS1 port.Figure 3-4 and Figure 3-5 show an example of setting up a drop and continue application.Figure 3-4 shows the Quick Setup menu before any DS1s have been dropped. Figure 3-5shows the same menu after DS1s 12–15 have been dropped from DS3 A to DS1 Ports 1–4,respectively. DS1s 1–11 and 16–28 continue through from DS3 A to DS3 B. DS1s 12–15 inDS3 B are now filled with AIS going out DS3 B.Amphenol ConnectorsBNC Connectors
