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.
Assume station exists (Do not send TEST frames)
When this parameter is enabled TEST frames are not transmitted and the TEST response is
not expected. Instead the unit assumes the station exists and proceeds with the protocol as
if the DLSw has received the TEST response.
Toggle DCD output each time the DLSw protocol enters the DISCONNECTED state
When this parameter is set to “On”, the DCD (Data Carrier Detect) output will turn off
briefly each time the DLSw protocol enters the DISCONNECTED state. Thus any attached
equipment that needs to will see signals changing state.
Sync port should not send or receive data when WAN link is down
This parameter causes the Sync port to be deaf and dumb (and have DCD low) while the
connection with the WAN is down. This is so that some terminals don't get too excited just
because L2 is up and think everything else should be working (and go into a management
error state).
