Description
This parameter allows you to enter a name for this SNAIP instance, to make it easier to
identify.
Send SNAIP traffic over interface
This setting determines which physical interface is to be used for carrying SNAIP data. This
can be set to either “ISDN”, “Serial Port” or “SharedPort”. If “ISDN” is selected then SNAIP
data is carried over the ISDN BRI physical interface. By selecting “Serial Port”, SNAIP data
can be routed to either serial “Port 0” or serial “Port 1“ (operating in synchronous mode). To
configure Port 0 or Port 1 for synchronous operation refer to the Configuration - Network
> Interfaces > Serial > Serial Port x > Sync Port x.
If "Shared Port" is selected, the drop down list next to “Shared Port” specifies the SNAIP
instance that has sync port configured. When sync port sharing is enabled only one SNAIP
instance can currently own the sync port. Other SNAIP instances however can share this
sync port in the event that there is more than one terminal residing on a multi-drop sync
line In this situation with multiple terminals, each terminal station will operate a DLSw
state independently of all other stations.
The SNAIP parameter "Priority" is used to select the SNAIP instance to use when more than
one is available; the highest number being given preference.
As an example consider that 4 SNAIP instances to all share sync port 0. To do this,
configure SNAIP 0 in the usual way on "PORT 0" and then configure SNAIP instances 1,2 & 3
to use "SharedPort" and “Sync Port from SNAIP 0”
Use protocol
This parameter sets the appropriate protocol for the interface. Choose “LAPB”, “SNA” for
SDLC or “RAW” for raw mode in which all L2 frames are transmitted and received. You can
also choose “RAW_NOHDR” for raw mode with no DLSw headers.
Allow this unit to answer calls
If this parameter is set to “On”, the unit will answer incoming calls on the relevant LAPB
session. To prevent the unit from answering incoming calls on this LAPB session set the
option to “Off”. This setting is only relevant when the interface is set to ISDN.
Only accept calls with MSN ending with
This parameter provides the filter for the ISDN Multiple Subscriber Numbering facility. It is
blank by default but when set to an appropriate value with answering calls parameter above
enabled, it will cause the unit to answer incoming calls only to ISDN numbers where the
trailing digits of the called number match the MSN value. For example, setting the MSN
parameter to 123 will prevent the unit from answering any calls to numbers that do not end
in 123. This setting is only relevant when the interface is set to ISDN.
Only accept calls with sub-address ending with
This parameter provides the filter for the ISDN sub-addressing facility. It is blank by default
but when set to an appropriate value, with answering calls parameter above enabled, it will
cause the unit to answer incoming ISDN calls only where the trailing digits of the sub
address called match the Sub-address value. For example, setting the Sub-address to 123
will prevent the unit from answering any calls where the sub-address called does not end in
123. This setting is only relevant when the interface is set to ISDN.
