• In the tributary name field enter a tributary name/identifier.
The name entered in this field is also displayed in the System/Controls
screen for the same DAC.
• The Status icons provide a direct indication of any tributary input or output
problems. The icons shown in the Figure 7-10 example indicate no problems
exist.
• The tributary port is provided via a plug-in single-mode LC transceiver
sub-assembly. Two different sub-assemblies are available; short range, and
long range. Both meet Class 1 eye safety.
For the preferred APAC Opto
tm
transceivers:
Short range specifies a minimum input power of -34 dBm (max.
sensitivity), and a maximum input power of 0 dBm (saturation). The
transmit level limits are: min. -15 dBm, max. -8 dBm. Center Tx
wavelength is between 1261 and 1360 nm (typically 1310 nm).
Long range specifies a minimum input power of -35 dBm (max.
sensitivity), and a maximum input power of 0 dBm (saturation). The
transmit level limits are: min. -5 dBm, max. 0 dBm. Center transmit
wavelength is between 1260 and 1355 nm (typically 1310 nm).

• LOS alarms are suppressed
• AIS alarms are suppressed
• At the optical interfaces the output is
disabled
• Receive traffic will cause an
‘uncommissioned traffic alarm’ in
Events Browser and Alarms screens
• Trib traffic is enabled
• LOS alarm is raised if LOS is
detected
• AIS alarm is raised if AIS is
detected
For protected DAC 155oMs, LOS on the line interface is a switching condition.
Ensure the line trib is commissioned (commissioned tick-box is ticked).
