The receive traffic descriptor index. The reason why
we duplicate this index is to allow the user to change
the traffic descriptor without deleting the connection
AND without any changes to the RFC1695.mib. RFC1695
describes the traffic descriptor indices only the
vcl/vpl tables. Hence if the user wishes to change
the TD after creating the cross-connection, then the
user has to
delete the cross connection to ensire that the receive
direction of the low end of the cross connect is equal
to the transmit direction of the other VCL at the high
end of the cross connect.
10/18/96. Since we dont want to create Vcl without
cross connecting them, NMS will now call this table
which would allow the creation/deletion and
modification of Cross Connect Entries.
