Operation3-293160-A2-GB21-80 March 1999Configuring DS0 ChannelsThe DSU/CSU provides channel configuration options that allow you to do thefollowing: Display the DS0 assignments for the network, DTE Drop/Insert (DSX-1), anddata port interfaces. Allocate DS0 channels on the DTE Drop/Insert (DSX-1) interface to thenetwork interface. Allocate DS0 channels on the network or DTE Drop/Insert (DSX-1) interfaceto particular data ports. Clear (deallocate) all DS0 channels from the network, DTE Drop/Insert(DSX-1), or data port interface. Map data from one port to another.To allocate DS0 channels, begin by defining the logical channel configuration forthe network interface, and then the DTE Drop/Insert (DSX-1) interface, and thenany ports, if desired. See Figure 3-6 for an example of a conceptual diagram of achannel configuration.Blank configuration worksheets are provided at the back of Appendix C,Configuration Options. To complete the configuration worksheets for DS0 channelallocation:1. Complete the Network Interface and the DTE Drop/Insert (DSX-1) Interfacetables (unless the DTE Drop/Insert interface is disabled) as shown in theexamples in Figure 3-7 and Figure 3-8.2. Complete the Robbed Bit Signaling (RBS) information worksheet as shown inthe examples in Figure 3-9.3. Using the worksheets shown in Figures 3-10 and 3-11, circle theconfiguration options needed to implement the logical channel configuration.Once you have completed the worksheets, enter this information using theprocedures inAllocating Data Ports on page 3-38.
