5.4.3 Reset Reason
If the BTS undergoes a fatal software reset of any sort, a byte indicating the "reset reason"
is stored in memory before the reset is initiated. During the reset procedure, this "reset
reason" byte is read out, and sent to the management system as a Failure Event Report.
5.5 Configuration
5.5.1 DHCP
The BTS supports the ip.access specific implementation of DHCP.
5.5.2 Fallback OML Link
The BTS supports a fallback link to its BSC, by configuring the "Primary OML Fallback
Address" and "Port" and the associated "Fallback Timeout". If the fallback address and
port are configured, then the BTS will behave as follows
On startup, the primary, non-fallback address is repeatedly tried, until either
connection succeeds or the fallback timer expires
If the fallback timer expires, then the fallback address is repeatedly tried, until either
connection succeeds or the fallback timer expires
If the fallback timer expires, then the non-fallback address is tried again, and so on
If the fallback timer is zero (its default value) then the non-fallback and fallback addresses
are tried alternately.
If the fallback address and port are unconfigured, then the non-fallback address is tried
repeatedly for ever.
5.5.3 Management Model and Attributes
The management model is fully defined in [REF_110]. An example class tree for the
1800MHz EDGE/AMR BTS is given below.
