The line items in Exhibit 9 are the ones that create and initialize the core components to the
BTS’s on-board file system. This file system is used to store operating code images,
configuration data, and log files. The BTS Operating System software handles the images, data,
and files and does not require operator assistance.
There are three on-board file systems’ FLASH and RAM drives. The FLASH drive is at /tffs0
and the two RAM drives use /dev0 and /dev1. All on-board file system drives have dedicated
functions and should not be altered or used through manual operations.

The sequence shown in Exhibit 10 initializes the TCP/IP stack on the BTS. The TCP, UDP, IP,
and ARP protocol stacks are created. Interfaces for the stack are then created and attached to the
stack. Three or four interfaces are created depending on the selection for “traffic path” in the
boot parameters.
The Fast Ethernet Controller, fec (0), is created and attached for the 10/100 Ethernet ports on the
BTS. If “atm” is selected, then a WAN Ethernet Controller, WEC (0), is also created and
attached to the stack to perform RFC1483 Ethernet bridging onto the ATM interface. Internally,
the BTS utilizes a high-speed SLIP interface, sl (0), to provide communication between
redundant devices. Finally, a debug local loopback interface, lo (0), is created and attached.
