involved. When the carrier provides a timing signal, all other
devices on the T1 must use that signal to derive their transmit
clock. Use the “B” command for the DIU timing options and
select “5” for NET (recovered NETwork clock).
5. There are no more changes required to the default CSU
configuration in order to configure this example. Use the “X”
command to return to the SCC 2020 Main Menu.
Configuring the
DIU 2130
For this example, the SCC 2020 is used with a DIU 2130 module in
the right hand side (slot 2) of a Dual-line Shelf. The SCC 2020
connects directly to the T1 circuit and provides CSU functionality.
The DIU 2130 presents two synchronous serial interfaces for
connecting the Data Terminal Equipment (DTE) and provides DSU
functions.
Before any module may be optioned, it must first be selected. When
you first logged in to the SCC 2020 the default was that the SCC
was selected. To configure the DIU 2130, first select it.
The S) shelf/slot S) shelf/slot S) shelf/slot S) shelf/slot command is used to navigate from one module to
another. Type “S” and press E NTER . The prompt for selecting
another module appears: Enter shelf,slot > Enter shelf,slot > Enter shelf,slot > Enter shelf,slot > For this example the
node has only one shelf (shelf #1) and the DIU 2130 is in slot two of
that shelf. Type “1,2” and press E
NTER .
The prompt line returns as: [1,2] DIU 2130 (UPDATE) > [1,2] DIU 2130 (UPDATE) > [1,2] DIU 2130 (UPDATE) > [1,2] DIU 2130 (UPDATE) > this indicates
that the DIU 2130 has been selected.
NOTE: Whenever the word UPDATE appears in the command line
prompt, it indicates that some information has changed since
the screen was last refreshed. To refresh the screen with
current information, simply press E NTER .
Configuration
Menu
Type “C” and press E NTER to select the DIU 2130 Configuration
Menu. There is a brief delay as the SCC module attempts to
communicate with a CSU module in Shelf 0, Slot 0 since this is the
default value for CSU assignment in a new DIU 2130 module. An
address of Shelf 0, Slot 0 is not possible. Modules are shipped this
way in order that they may be added to a shelf without interfering
with any existing applications. An error message appears:
No response from csu[ 0,0 ] No response from csu[ 0,0 ] No response from csu[ 0,0 ] No response from csu[ 0,0 ].
This error message, in this case, means that the DIU 2130 is new
and has never been assigned to any CSU module in any slot of any
shelf. Ignore this error message.
Then the DIU 2130 Configuration Menu is displayed.
