ISDN Settings parameters
Use number x to make outgoing ISDN calls
Used to specify an ISDN number. Use when no ISDN number is provided with the ATD command
when making an outgoing call.
Use prefix x
A dialing code the router places in front of the telephone number that is issued by the terminal in
the ATD command. For example, if the Use Prefix setting is set to 0800 and the number specified
by the terminal in the ATD command is 123456 , the actual number dialed by the router is
0800123456 .
Remove prefix x from number in ATD command
A dialing prefix that is normally inserted by the terminal in the ATD command that is removed by
the router before dialing takes place. For example, if the Remove prefix setting is set to 0800
and the terminal issued an ATD command containing 0800123456 , the actual number dialed by
the router is 123456 .
Use suffix x
The Suffix # parameter may be set to contain additional numbers that are dialed after the
number specified by B-channel ISDN #. For example, if B-channel ISDN # is set to 123456 and
Suffix # is set to 789 , the actual number dialed is 123456789 .
On the main interface
Deactivate LAPB session x seconds after TPAD X.25 call has been cleared
Once a TPAD X.25 call has been cleared, the router keeps a LAPB instance active for the length of
time set by this parameter. This allows further TPAD transactions to occur without having to
make another ISDN call. The default value of 10 seconds is acceptable for most applications. The
value of 1 is a special value which means terminate Layer 2 immediately the transaction is
finished. (When the X.25 call is cleared.) If you select LAPD as the TPAD Layer-2 interface, this
value is automatically be set to 0 to disable Layer-2 deactivation. You can override the 0 setting
by entering a new value, but most network service providers prefer that LAPD connections are
not repeatedly deactivated.
On the backup interface
Deactivate LAPB session x seconds after TPAD X.25 call has been cleared.
Equivalent to the deactivation timer above, but applies only to backup calls.
