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.

Next, the user interface through the console port on the BTS is activated. It should be noted

however, that once the Telnet Daemon has been started, this same interface is available remotely

through a password protected telnet session. You can access the remote shell service by

telnetting directly to the well-known Telnet port (23) of the BTS:

This invokes a suite of tools accessible by the Navini developers to assess runtime loads of

various components in the system:

Starting Load Monitoring Tools............Done

This creates a database of commands that can be issued from the shell:

Loading Target Shell Symbols..............Done

This in turn invokes a suite of tools accessible by the Navini software developers to access

runtime debugging of the system:
