5.5.4 Code Download

The BTS supports code download by using the software download function of the

BtsInstaller tool (see [INST_300]).

The BTS examines the header of the downloaded file to determine if the BTS hardware is

compatible with the SW. If any part of the code download is incompatible with the

hardware, then the code download is NACK’d and the transfer is aborted, without affecting

the running or the stored code.

For DHCP triggered TFTP, once the code has been successfully downloaded and the

TFTP is complete, then the BTS shall set an internal flag (not set / get able from the

outside world) to "disable DHCP triggered TFTP on reboot" in EEPROM. The BTS shall

change the "Default" index to the index that it has just successfully downloaded. Then the

BTS should reset itself. Once reset the BTS shall clear this flag (so that on the next reboot

a DHCP triggered TFTP download is permitted) and begin executing this code.

If a code download fails or is aborted for any reason, then a Failure Event Report is sent to

the management system.
