Each ring builder has two external trunk connections by which
a ring builder may be connected to other token ring devices
capable of supporting a backup path, e.g. another ring
builder. Each external connection attaches to a dual ring
cable. One of the rings is used to carry traffic in a fault
free network. The other ring is used as a backup. If an error
should be detected on the main ring then suitable stations can
wrap the active path onto the backup. The ring builder is
such a device. The fault recovery is handled at the ring in
and ring out ports.
Each of these two connections may be placed in one of the
following states:
openRing (1):-
This external connection is configured to be connected
to the external ring. NOTE: In this mode if there is no
external ring the ring will be broken.
wrapRing (2):-
This external connection is configured to isolated from
the remote ring such that the external ring in/out port
is looped from main to backup ring.
failSafe (3):-
In this mode the ring builder monitors the ring in
signal for a phantom voltage. If this is present then
the external connection is placed into OPEN state. If
the phantom voltage is not present then the external
connection is placed in WRAP state. In this mode the
actual state of the connection can be obtained by
reading the state parameter.
Note that not all devices support the generation of a phantom
voltage and so the FAIL-SAFE mode may not be appropriate.
