â– CONFIGURATION-Enter-Crossconnection-STS3: This input enters a
1-way, 1-way-DRI, 2-way cross-connection.
— A
1-way
cross-connection is entered by specifying a 1-way source
and destination. The source may be a low-speed interface slot, a
low-speed interface slot in a slot pair (for example, slot 2A and 2B)
provisioned for the OC-3 1+1 protected mode, or an STS-3 tributary.
If the source is a low-speed interface slot, the destination must be
an STS-3 tributary. If the source is an STS-3 tributary, the
destination must be a low-speed interface slot, a low-speed
interface slot in a slot pair provisioned for the OC-3 1+1 protected
mode, or the same-numbered STS-3 tributary on the OC-48
high-speed line in the opposite direction. If the source is an STS-3
tributary, the source node TID must be specified. If the destination is
an STS-3 tributary, the destination node TID must be specified.
An input requesting a 1-way cross-connection will be denied if the
specified destination is already cross-connected to a different
source, or the destination is already involved in a 1-way-DRI
cross-connection. An input requesting a 1-way cross-connection will
not be denied if the specified source is already cross-connected to a
different destination. (The bridging capability allows two or more
cross-connections to share the same source.)
— A
1-way-DRI
cross-connection is entered by specifying a 1-way
source and destination. The source is always a low-speed interface
slot or a low-speed interface slot in a slot pair (for example, slot 2A
and 2B) provisioned for the OC-3 1+1 protected mode, and the
destination is always an STS-3 tributary. The DRI secondary node
TID and the destination node TID in the ring must also be specified.
An input requesting a
1-way-DRI
cross-connection will be denied if
the specified destination (always an STS-3 tributary) is already
involved in a 1-way, 2-way, or 1-way-DRI cross-connection. An input
requesting a 1-way-DRI cross-connection will not be denied if the
specified source is already cross-connected to a different
destination. (The bridging capability allows two or more
cross-connections to share the same source.)
