Administration and Provisioning
8-68 Issue 8.0 July 2002
The following rules should be observed when specifying the source node TID,
secondary node TID, and destination node TID parameters.
â– The value of the source node TID parameter (1-way cross-connections)
and the value of the secondary node TID parameter (1-way-DRI
cross-connections) must be the
same
at all nodes. The value must be the
TID of a node where there is a 1-way-DRI cross-connection.
â– The value of the destination node TID parameter depends on exactly what
cross-connections are present. To determine the value of the destination
node TID at the local node, assign the following:
— X is the TID of the local node.
— Y is the TID of the next downstream node with a 1-way-DRI
cross-connection. X and Y will never be the same node.
— Z is the TID of the last node with a 1-way drop cross-connection
when following the circuit from node X to node Y. Z can be node X or
Y, some other node between X and Y, or null if there are no 1-way
drop cross-connections between X and Y.
If Z is X or null, use the TID of node Y as the value of the destination node
TID parameter. Otherwise, use the TID of node Z as the value of the
destination node TID parameter.
The following cross-connections are required to establish the circuit shown in
Figure 8-21:
â– At node 0, a 1-way drop cross-connection is entered by specifying:
— Source (tributary)
— Source line (line 1W)
— Source STS-3 tributary (tributary 6)
— Source node TID
*
(node 0 TID)
— Destination (slot)
— Destination low-speed interface slot (slot 4A).
â– A 1-way-DRI cross-connection is entered by specifying:
— Source low-speed interface slot (slot 4B)
— Destination line (line 1E)
— Destination STS-3 tributary (tributary 6)
— Destination node TID* (node 2 TID)
— Secondary node TID* (node 0 TID).
* In Release 4.1 and later releases, entering a question mark (?) in response to the TID
prompt will display a point-and-shoot list of available addresses in the OC-48 ring. Enter
the Retrieve-Map-Ring command to update the point-and-shoot list.
