Logical interconnection

WT section

A WT section can be interconnected in a 64k channel.

WT trail

A WT section can be interconnected in a WT section.

When wiring up a WT service in a WT section, a channel with indication of channel number, and optionally, of the frequency range, is created automatically in this section. Each channel can only be contained once within this section.

Frequency plan

The interconnection structures are obtained based on the frequency plan used in ConnectMaster :

Multiports

A WT trail can end on “multiports” in addition to the two end ports if the type “Bus ring” was defined as topology.

“dead” branches

A trail may lie in “dead branches” via so called solder points.  

It can be identified as such in the routing table; as a result, when using the switch-off management, the trail is not detected as faulty if the WT section is disrupted.
