The general principle in setting up the SONET frame is to select the relevant
values for the various containers in the multiplexing structure. This is done
either via a drop-down menu or via a launched dialog box, by touching a
drop-down menu or a button in the frame structure diagram.
Note that the currently 'active path' in the structure is highlighted. Note also
that the changes you make will be reflected in the text displayed in the
SONET button in the navigation area, if relevant.
To make the Port 2 transmitter follow the Port 1 transmitter (i.e. copy its
settings), touch the right-most button in the navigation area and select the
Tx1 in the drop-down menu. The Port 2 settings continue to follow the Port 1
transmitter change. The default setting is None. Note that the Port 1
transmitter cannot follow the Port 2 transmitter.
Select the TCM (Tandem Connection Monitoring). The available TCM is
decided by multiplex structure. If you select other TCM, the multiplex
structure on the setup area will be changed.
The possible settings are:
Off
Z5 (STS-3c)
Z5 (STS-1)
Z6 (VT-2/1.5)
Allows you to switch between SDH and SONET.
You can configure transport overhead (TOH) in a special dialog box (TOH
Editor), which is launched when you touch the TOH button.
