V.25 bis Autodialer
Modem 3600 11-9
If circular linking (1 to 8 to 7 to 1) is used, dialing is discontinued after
the addressed number in the dial command has been dialed twice. If
only one parameter follows the PRL command, the number at address a
is unlinked from its forward link.
For example, if the link list 4 to 8 to 3 to 7 to 9 to 1 exists and PRL 7 is
received, 7 would be unlinked from 9, but not from 3. This would result
in two link lists: 4 to 8 to 3 to 7 and 9 to 1.
