This chapter describes how to set up a connection to a remote host over a high-
speed serial interface (HSI) using point-to-point protocol (PPP).
The SunLink™ High-speed Serial Interface (HSI) controller card is a four-port
serial communications SBus card. When used with Data Service Unit or
Channel Service Unit (DSU/CSU) equipment (available from third parties) the
HSI controller card can be used to communicate over 1.544 Mbps T1 or 2.148
Mbps E1 telephone lines.
While DSU and CSU are two separate entities, they
are often combined in one physical unit
. The CSU is the point of contact for the
T1 line, and provides termination and signal regeneration for the T1 line. The
DSU converts signals from the router into the bipolar digital signals used by
the digital line.
Note – The Netra software only displays information about network interface
hardware that is currently attached to the Netra server. (Refer to your Netra
hardware installation manual for instructions on adding network interface
hardware. See the “Software Management” module in Chapter 19 for software
installation instructions.)
The High-Speed Serial Interface module only supports the SunLink PPP 2.0
software. SunLink PPP 3.0 and SunLink PPP 3.0.1 are not supported.
