Compatible Systems HSSI-10/100 User Manual

Suggested for DECnet
Setting the parameters above should be adequate for most installations.

In order to use the WAN interface, you may want to set some physical parameters.  Then set up 
the link and protocol parameters.

Required for Dedicated Line Operation
No changes from the default values are required for standard operation over a T3 line.  The 
default values are listed in 

.

Suggested for Dedicated Line Operation
Changing to a different clocking or CRC setting may be required. These parameters can only 
be set using the command line interface. 

TB:  Use configure and the HSSI Interface WAN 0 section.

This section covers the settings required for PPP (point-to-point) protocol operation of the 
HSSI WAN interface. 

Required for Dedicated Line Operation
This is the only mode of operation supported via the built-in HSSI CSU/DSU.

•

Set Dedicated connection

•

Set PPP connection

CV:  Use the Link Configuration: WAN Dialog Box.

TB:  Use configure and then set the Mode and ConnectMode keywords in the Link Config 
WAN 0 section.

Suggested for Dedicated Line Operation
Dedicated line operation generally does not require additional parameters for operation.

Required for IP
WAN interfaces which are set for PPP operation do not generally use an IP address.  They are 
set to act as an “unnumbered interface.”  In this mode of operation, there are no required 
settings.

Suggested for IP
These parameters help supply information about the segment that the interface is connected to.  
With this information, routing can take place.  

•

Set IP RIP 1, IP RIP 2, OSPF (Open Shortest Path First) or BGP (Border Gateway 
Protocol)

•

Set IP static routes

CV:  Use the TCP/IP Routing: WAN Dialog Box to set RIP, and the IP Static Routing Dialog 
Box (under Global/IP Static Routes) to set static routes.  OSPF and BGP can only be config-
ured using text-based configuration.
