Alarm Name Alarm Description
400 Traffic Channel
Element Failure
This trouble notification indicates the availability of a single channel
element or a set of channel elements. It is generated whenever the BTS
detects an alarm condition on a DSP, its internal path connection, or its
associated span. It is never displayed or latched in the MM and it is only
used to update the MM’s call processing resource list. This trouble
notification contains the address of the channel card along with the list of
affected channel elements.
1200 BTS LAN Connection
Error
This alarm causes the MM to take the BTS out of service. The MM
converts the alarm ID from 1200 to 12–60 (MAWI out of service).
