Establish Remote Login
1. Connect CIT and establish session with near-end DDM-2000.
Reference: DLP-521
2. NOTE:
The command
toggle
(Ctrl T) may be used to toggle back and forth
between a remote DDM-2000 terminal and the near-end terminal. If no
remote session is in progress, the toggle command will be rejected.
NOTE:
A remote login within a remote login or a remote login entered to the near
end while a remote session is suspended by the toggle command is not
allowed. (A remote session is suspended when a remote session is
under way and
toggle
(Ctrl T) is entered to toggle control to the near
end.) A remote login will also be denied if one is already in progress at
the remote site.
NOTE:
If security has been enabled on the DCC port being accessed, a login
and password are required to do the remote login.
NOTE:
Far-end communications (fecom) must be enabled in the far-end shelf in
order to remote login to that shelf. The command
rtrv-fecom:
can be
used locally at the far-end shelf to determine if
fecom (DCC/LAN) is
enabled or disabled. The
set-fecom:
command can be used at the
far-end shelf to enable DCC/LAN communications. If security is enabled,
the
set-fecom:
command can be executed by privileged users only.
NOTE:
Remote login to FT-2000 OC-48 systems are not allowed from the
DDM-2000 OC-3 system.
NOTE:
A remote login session may be terminated in some cases due to events
in distant shelves and may not be noticeable until you begin typing in the
rlgn session. Events such as disabling fecom, failure of the DCC or LAN,
init-sys:
or
reset
, removing OLIUs, etc., may abruptly terminate a
remote login session. This is normal because all the network elements
must relearn the network after one of these events.
