•The Control (Ctrl) branch provides the ability to
display and change external leads, enable or disable
the DSU-DBM, and access and monitor the external
leads for Ports 1 through 6. The circuit designation
status indicators (TXD, RXD, etc.) reflect the status
of the selected port.
NOTE
In most of the examples that
follow, additional menu
selections that do not fit onto the
DSU’s screen are shown
beneath the DCP. To display
those menu selections, press
the or key to scroll the
selections into view.
Each selection leads to a functional subbranch of the
menu tree. Five factors determine which selections or
options are available.
•Whether the DSU is in Display mode and the
DSU’s mode of operation.
•Whether the DSU is a control or tributary.
•Whether your selections are from the Local or
Remote branch (Local or Remote mode).
•Whether a DBM is installed.
•Whether a TDM or MCMP is installed.
Refer to the menu in Appendix A. You will see Port
Select under some of the menu selections, which means
that a Port Number screen will appear when operating in
TDM, MCMP, or Bridge mode. Use the F1 and F2 keys to
display the port number of your choice; then press the F3
key to activate your choice.
The following sections highlight only those areas of the
DCP menu and operation that are unique to operating in
TDM, MCMP, or Bridge mode.
For information on how to access menu branches and
DCP operation (regardless of the options installed), refer
to the COMSPHERE 3600 Series Data Service Units,
Models 3610 and 3611, Operator’s Guide.
Status Branch
The Status (Stat) branch reports on the health and
status of the DSU and DBM, the DTE interface, the
quality of the PSTN connection, the identity of the DSU
(model number, serial number, etc.), and the terminal’s
power. (It checks the presence of voltage on the DTE’s
RTS lead on Port 1). For a DSU with TDM or MCMP, the
health and status of the TDM or MCMP is integrated into
the health and status of the DSU.
Of the five Status branch selections shown below,
CircQ (Circuit Quality) only appears when a V.32 DBM is
installed.
