Continued from Page A-1.
Press a function key to select one of the following
branches:
• Local branch
• Remote branch – Only available to a DSU
configured as a control or a point-to-point tributary.
• Messages branch – Only appears when a message
from the NMS is waiting. Once the message is
cleared, this branch no longer appears.
Local/Remote Menu Subbranches
The Local branch menu has five subbranches; the
Remote branch menu has four:
• The Status (Stat) branch provides reports on the
health and status of the DSU and DBM, the DTE
interface, the identity of the DSU and DBM, the
status of the connected DTE’s EIA-232 and V.35
interfaces, and if there is a dialed connection, the
quality of the dial network circuit. If a TDM/Flex is
installed, its status is integrated into the DSU’s
status.
• The Backup (Bckup) branch controls the operation
of the dial backup feature. This branch is available
if a DBM or an external dial backup unit (DBU) is
installed. Only available from the Local branch.
• The Test branch provides extensive testing
capabilities for the DSU; the DDS circuit; the
DBM, if installed; and the backup circuit, if there is
a backup call established. If a TDM/Flex is
installed, testing is available on a per port basis.
NOTE
If the Test branch does not
appear, the DSU is in Display
mode (values can be read, but not
changed).
Only authorized persons can
change configuration option
values for the DSU. Contact your
System Administrator
for further
information.
• The Configuration (Confg) branch provides the
ability to customize DSU software configuration
options, to enter and change telephone numbers (if
a DBM is installed), to change the DSU network
address, and to specify the menu mode for
displaying configuration options of the unit.
• The Control (Ctrl) branch provides the ability to
display and change external leads and enable or
disable the DSU or a DBM or TDM/Flex, when
installed. When a TDM/Flex is installed, the circuit
designation status indicators (TXD, RXD, etc.)
reflect the status of a selected port.
Each selection leads to a functional subbranch of the
menu.
Only three menu selections appear at a time, one over
each function (F1, F2, F3) key. Press the
and
keys to scroll backward or forward through menu
selections.
• Press the
key to go to the previous
screen/menu display.
• Press the
key to return to the starting point –
the top-level menu.
Refer to Chapters 4 and 5 for additional DCP operation
information.
