Naming
DATA/DAC (Module) Name. A name can be entered or a name changed by
right-clicking within the DATA module in the System Summary screen, selecting
Rename, and typing. The default name is ‘unnamed’.
• The name entered will appear in all CT screens where the DATA module
function is identified. Includes Plug-ins, Protection, Circuits, System
Summary, and System/Controls screens.
Trib Naming
. Trib names should relate to its circuit name to permit easy
association of trib with circuit when setting a DAC BER test using the circuit
loopback feature. Trib names are entered in the DAC Plug-ins screens; circuit
names are entered in the Circuits screen.
Tributary Protection
Tributary protection on a Node is provided by operating two identical DACs as a
protected pair. Refer to Node Protection on page 8-1 for configuration
information.
Tributary protection on a protected Terminal is provided by operating two
identical IDUs as a protected pair. Refer to Terminal Protection on page 8-17 for
configuration information.
Two tributary protection options are provided on the IDU 155o, three on the IDU
20x. Tributary protection and tributary always-on applies to both IDUs; hot
standby: no tributary protection applies only to the IDU 20x.
Tributary Protection (TT)
• ‘Y’ cables connect the paired DACs/IDUs to customer equipment.
• In the Rx direction (from the customer) both DAC/IDUs receive data, but only
the online Rx DAC/IDU sends this data to the bus/radio.
