If the expected result does not appear, determine the cause in accordance with
Subsection 7.4.2, “WAN line cannot be connected”.

(4) Assurance on ATM Line
[Example]
To assure the ATM line, enter the show nif (ATM) command from the device
management terminal as follows:
> show nif 0 [CR]
The result will appear as Figure 8-38, which assumes that the NIF No. 0 is an NIF of
OC-3c/STM-1 ATM (multimode) and the corresponding line No. 0 is connected to an
applicable device, e.g., DSU or ATM switch. In this example the line is enabled
because of the following:
The subject NIF is operating normally (in this example, “NIF0: active”).
The subject line is operating normally (in this example, “Line0: active up”).
If the expected result does not appear and the line is not operating normally (“Line0:
active up” is not given), ensure the following:
Is the cable disconnected or loosely connected?
Is multimode cable used? (Is single-mode cable mistakenly used?)
Is startup of the connected device complete?
