Configure Systems Network Architecture over IP (SNAIP)
Digi TransPort User Guide 502
Only accept calls with sub-address ending with
This setting is only relevant when the interface is set to ISDN. This is the filter for the ISDN sub-
addressing facility. By default, this setting is blank. When set to an appropriate value, with
answering calls parameter above enabled, the router answers 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 prevents the router from answering any calls where the sub-address
called does not end in 123.
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 router 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 turns off briefly each
time the DLSw protocol enters the DISCONNECTED state. Any attached equipment that needs
to will see signals changing state.
Sync port should not send or receive data when WAN link is down
Causes the Sync port to be deaf and dumb (and have DCD low) while the connection with the
WAN is down. This setting is supported to prevent terminals from assuming if L2 is up, the rest
of the WAN link should be working, at which point the router could go into a management
error state.
SNA parameters
Router to be Master on an unbalanced link
Enable this parameter if this router is to be the master in an unbalanced link, or set to Off if
the router is to be a secondary station.
Polling Response Time
The poll time, in milliseconds, if the router is the master in an unbalanced link.
Polling Stations Addresses
This parameter is only applicable in SNA mode. Lists the station addresses on the data link as
a comma-separated list of hex values, such as c1,d1 for station addresses 0xc1 and 0xd1.
SAPs
A list of SAP values which correspond to the station addresses.
DSAPs(blank=default)
The Destination SAP value, if left blank the SAP value above is used.
Send Null XID (XID with no Data)
When this parameter is set to On, a null XID SSP message will be sent when the router has just
received or sent a REACH ACK SSP message.
Send XID with Data
A hex string to define binary data and defines an XID SSP message that would be sent in
response to a XIDFRAME SSP message being received.
