Configuring DS0 Channels
The DSU/CSU provides channel configuration options
that allow you to do the following:
•Display the DS0 assignments for the network, DTE
Drop/Insert (DSX-1), and data port interfaces.
•Allocate DS0 channels on the DTE Drop/Insert
(DSX-1) interface to the network interface.
•Allocate DS0 channels on the network or DTE
Drop/Insert (DSX-1) interface to 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 for the network interface, and then
the DTE Drop/Insert (DSX-1) interface, and then any
ports, if desired. See Figure 3-6 for an example of a
conceptual diagram of a channel configuration.
Blank configuration worksheets are provided at the
back of Appendix C, Configuration Options. To complete
the configuration worksheets for DS0 channel allocation:
1. Complete the Network Interface and the DTE
Drop/Insert (DSX-1) Interface tables (unless the
DTE Drop/Insert interface is disabled) as shown in
the example in Figure 3-7.
2. Complete the Robbed Bit Signaling (RBS)
information worksheet as shown in the example in
Figure 3-8.
3. Using the worksheets shown in Figures 3-9
and 3-10, circle the configuration options needed
to implement the logical channel configuration.
Once you have completed the worksheets, enter this
information using the procedures in the Allocating Data
Ports section on page 3-27.
