The NCS 2002 relies on the protective devices in the building installation to protect against short circuit,
overcurrent, and ground faults. Ensure that the protective devices are properly rated and comply with
national and local codes.
Caution
The battery return connection is treated as DC-I, as defined in Telcordia GR-1089-CORE Issue 5.Note
If the system loses power or both TNC, TNCE, TSC, or TSCE cards are reset and the system is not
provisioned to get the time from a Network Time Protocol/Simple Network Time Protocol (NTP/SNTP)
server, you must reset the NCS clock. After powering down, the date defaults to January 1, 1970, 00:04:15.
To reset the clock, see the NTP-G24 Set Up Name, Date, Time, and Contact Information . If you are using
the TNC, TNCE, TSC, or TSCE cards, the system clock will run for up to three hours. In this case, no
action would be required.
