Configuring legacy protocols
Only accept calls from calling number ending with
The filter for the ISDN Multiple Subscriber Numbering facility. It is blank by default. When set to
an appropriate value with Allow this unit to answer calls enabled, the router answers
incoming calls only to ISDN numbers where the trailing digits match the MSN value. For
example, setting the MSN parameter to 123 prevents the router from answering any calls to
numbers that do not end in 123.
Only accept calls with sub-address ending with
The filter for the ISDN sub-addressing facility. It is blank by default but when set to an
appropriate value, with Allow this unit to answer calls 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.
Keep ISDN LAPB link activated when user sends a DISC or X.25 PAD session terminated
When this parameter is enabled, the following setting is enabled:
Wait x milliseconds before attempting to establish the LAPB link after B-channel
becoming active
This parameter sets the length of time (in milliseconds), that the LAPB instance will wait from
an ISDN B-channel becoming active before attempting to establish a LAPB connection, such as
the length of time for which the LAPB instance stays passive. The default is 0, as most ISDN
networks allow CPE devices to initiate a LAPB link. If your ISDN network does not permit CPE
devices to initiate the LAPB link you should set this parameter to a value that allows the
network sufficient time to establish the LAPB link.
Use as x a calling party number when making ISDN calls
This is Calling Line Identification. The router will only answer calls from numbers whose trailing
digits match what is entered in this field. The line the router is connected to must have CLI
enabled by the telecoms provider, and the calling number cannot be withheld.
Async Mux 0710 Parameters
Certain W-WAN modules use LAPB to perform multiplexing of serial channels. If using LAPB for
X.25 over ISDN or serial, you can ignore these settings. Do not change these settings unless
under the instruction of Digi Technical Support.
Mux 0710 mode
If enabled, configures the LAPB instance use for multiplexing of serial channels instead of X.25.
Mux mode
Controls the multiplexing mode.
DLC #
The data link channel number to use for this virtual ASY port.
ASY port
The physical ASY port over which to multiplex.
