1.4 External Check
Confirm the following items in advance.
The hardware installation check is complete.
The T2000 is ready.
The T2000-local craft terminal (T2000-LCT) is ready in the laptop.
All equipment on each NE has active and standby power supplies. Check
whether alarms need to be output.
The interface impedance (75 ohms or 120 ohms) of the DDF on each NE is the
same as that of tributary boards and tributary interface boards.
Clock protection is provided. The setting of the clock board is correct. To
achieve clock protection switching, it is required to provide synchronisation
