Configuring DS0 Channels
The E1 DSU/CSU provides channel configuration
options that allow you to do the following:
•
Display the DS0 assignments for the Network, DTE
Drop/Insert, and data port interfaces.
•
Allocate DS0 channels on the DTE Drop/Insert
interface to the Network interface.
•
Allocate DS0 channels on the Network or DTE
Drop/Insert interface to particular data ports.
•
Specify whether time-slot 16 (TS16) is reserved for
signaling information.
•
Clear (deallocate) all DS0 channels from the
Network, DTE Drop/Insert, or data port interface.
•
Map data from one port to another.
NOTE
If TS16 is reserved for signaling,
D16 will automatically be
assigned to N16, and DTE DS0
channels allocated to the network
interface must be connected to
the corresponding channel (e.g.,
D1 to N1, D2 to N2, etc.).
To allocate DS0 channels, begin by defining the logical
channel configuration for the Network interface, and then
the DTE Drop/Insert interface, and then any ports, if
desired. See
Figures 3-6 and 3-8 for examples of
conceptual diagrams of channel configurations.
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 E1 Interface and the DTE
Drop/Insert Interface tables (unless the DTE
Drop/Insert interface is disabled) as shown in the
examples in
Figures 3-7 and 3-9 .
2. Using the worksheets shown in Figures 3-10
and 3-11 , 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 3-28. Configuration options are
listed in Appendix C .
