Screen Display and Data Entry
Configure the system through use of an asynchronous ASCII terminal (or equivalent) connected to the
D/I Mux III. Configuration settings are stored in Non-Volatile Random Access Memory (NVRAM) on the
CCU, and may be used to reconfigure the system if there is power loss. The stored settings also allow
replacement line cards plugged into the same slot as the card removed to be automatically configured
upon installation.
Note:
On an NVRAM startup, all passwords, along with
ALL
other system configuration parameters are erased. While an
NVRAM startup allows entry that a lost password might otherwise disallow, it is a last resort measure because of the
complete erase feature! An NVRAM startup is accomplished by powering-up the CCU/MCU with both the Alarm Cut-
Off (
ACO)
and the (
BYP
) Bypass buttons simultaneously depressed and held for 60 seconds.
Each system function is accessed by a two-letter command at either the CCU system access screen, or
the MCU Main Menu screen for D/I Mux III parameters (
AC
). For the D/I Mux III system CCU, the first
letter is usually
D
for display, or
S
for set or modify. For the MCU, the first letter is usually
V
for view, or
M
for modify or set, and
R
for remove. For example, the user can enter a
VN
or
DP
command to display
current system parameter settings.
Commands to be entered are shown in
bold type
. A screen example follows each procedure
description. Values shown in square brackets (
[ ]
) are default values. If something other than the default
value is entered, the new value appears in the brackets the next time that parameter is edited. The enter
key, indicated by
[Enter]
in the text, is pressed after each entry to select the default or new values. To
make corrections, simply backspace and retype entries. To return to the prompt, press
[ESC]
from most
functions. To quit, press
[Q]
when the option appears.
Items displayed in the CCU/MCU Main Menu may change depending upon password level. This chapter
describes system operation from the standpoint of the System Administrator (Level 1 password). Lower
level passwords are restricted from some options, and when accessing a user menu, certain restricted
command options will not appear (e.g., as with IP address and password commands).
The Telnet server allows terminal emulation over LAN networks. This allows a Telnet user to log onto a
D/I Mux III and operate it as if connected to a local terminal. To avoid having two simultaneous
connections, a new log-in mechanism allows either interface—local terminal or Telnet terminal
emulation—to lock the other out while updating the local configuration.
Warning:
Do Not
enter a slash (
/
), a backslash (
\
), a colon (
:
), or
CTRL-P
while issuing commands. These are
Coastcom’s proprietary Machine Machine Language (MML) commands and, if used, will cause a system
lockup. If there is such a lockup, press the
ENTER
key repeatedly, until the system responds, or cycle
power on and then off again. System will respond upon re-power-up.
