STS3 Explanation to Figure 1
This report shows the primary, secondary, source and destination nodes. Observe
the following from the report (no DRI switch means traffic is coming from the primary
node):
• Scan the report in the Cross-connection column and locate a 1-way DRI. A
1-way DRI is a 1-way add cross-connection and a 1-way through cross-connec-
tion sharing the same outgoing tributary. Note that one of these cross-connec-
tions will be active (dashed line) while the other will be standby (dotted line). In
this report, the At Node column indicates Concord-MA is provisioned with a
1-way DRI cross-connection.
•Theprimary node is a node at which a 1-way DRI cross-connection has been
provisioned. In this report, Concord-MA is the primary node. Concord-MA is
also the active source node because the add cross-connection is dashed and
not dotted.
•Thesecondary node is given in the TID column associated with the incoming
tributary of the 1-way DRI. In this report, the secondary node is to the right
(East) of the 1-way DRI, Chicopee-MA. Chicopee-MA is also the standby
source node because the through cross-connect is dotted.
•Thedestination node is given in the TID column associated with the outgoing
tributary of the 1-way DRI. In this report, the destination node is to the left
(West) of the 1-way DRI, Worcester-MA.
• Note: If a DRI switch occurs and the secondary node becomes the active source
node, the through cross-connection will be dashed and the add cross-connection
will be dotted.
Additional information on this type of report is described in Chapter 11 of this manual.
