<h1>Transmission Equipment Alarm Handling</h1>

<p>This feature harmonises the Fault Code level alarm numbers
of the BSC and Nokia Talk-family, PrimeSite, and MetroSite base stations in
transmission equipment alarms.</p>


<p>The BSC supervises Nokia Transmission Equipment through
the OMU's Q1 service channels. In addition, the BTS can supervise transmission
equipment that is connected to a local Q1 bus. The BSC only sets generic Transmission
Equipment alarms – the reason for the alarm (the fault) has to be analysed
from the supplementary information bytes. With this feature, the BAC starts
to use the same Fault Code level alarm numbers and alarm texts as the BTS
(Nokia Talk-family, PrimeSite, and MetroSite) uses when a transmission equipment
fault is detected. The alarm number consists of 8000 + the Nokia Transmission
equipment fault code.</p>


<p>The following is an example of the BSC Transmission Equipment
alarm format:</p>

<p>In the example above, the supplementary information contains
the Q1 channel number in the BSC, the Q1 address of the equipment, the equipment
type, and the number and numbers that locate the faulty interface.</p>
