Remote Access Using the Data Communications
Channel (DCC) 6
The DDM-2000 OC-3 system supports CIT remote access from the local terminal
to a remote system using the data communications channel (DCC) over OC-N
interfaces or the IAO LAN. The DDM-2000 OC-3 system supports one incoming
remote login session and one outgoing login session over the DCC at a time. For
example, a local user can gain remote access to a remote DDM-2000 in the same
subnetwork at the same time a remote user at another DDM-2000 in the
subnetwork can gain remote access to the local system. CIT remote login is also
supported in multi-vendor subnetworks, but only between DDM-2000 Multiplexers
(or from FT-2000 to DDM-2000).
Operations Interworking (OI) also allows remote logins between DDM-2000 and
the
SLC -2000 Access System and from the FT-2000 OC-48 Lightwave System to
other Lucent 2000 Product Family systems in the same subnetwork.
