Hardware Features
Fiber Interface
The LCS60 supports a single multiplexed fiber interface to the data switch CPM-
HS module. This is a distinct advantage in terms of cable management and effi-
ciency over traditional terminal servers which require separate asynchronous
connections.
Network Security
Complete network security is achieved through the Lucent Technologies Net-
work Access Control (NAC) System. When a data-switch connected modem
accepts a call from a remote user, a PDD can force that user to authenticate
through a NAC. Once authenticated, the user can request a TCP gateway session
or a remote access session (such as ARAP, PPP, or SLIP) with an LCS60 by means
of a simple dialstring. From the LAN, all sessions bound for the data switch net-
work can be forced to be authenticated by means of the TCP service port feature.
Additionally, the LCS60 supports a first-time authentication option with the
NAC. This option requires the LAN users to authenticate only once with the
NAC as long as the TCP/Async session remains open with the LCS60. The
actual duration time of an authenticated session is a NAC-dependent variable.
Therefore, consult the NAC documentation (refer to the section Reference Docu-
mentation in this chapter) for complete details on this feature.
