3. The system starts and sets the internal clock/calendar is set to 0:00:00 Saturday,
January 1, 2000.
4. The phone activates the Ethernet line interface to allow the start of procedures. The
activation occurs soon after power-up or a reset.
The phone displays the speed of the Ethernet interface in Mbps, that is, 10, 100, or
1000. The phone then displays the message Program below the speed until the
software determines whether the interface is 10 Mbps, 100 Mbps, or 1000 Mbps.
5. The IP phone sends a request to the DHCP server and invokes the DHCP
process.
The phone displays one of the following messages:
• DHCP: s secs
where s is the number of seconds that have elapsed after the DHCP process was
started. The phone displays the first message if 802.1Q tagging is off and access
to local programming procedures is not disabled or restricted. For more information,
see
Chapter 3: Using Local Administrative (Craft) Options . on page 25 The phone
displays the second message if 802.1Q tagging is on and access to local
programming procedures is disabled or restricted. If the first and second message
alternate every 2 seconds, 802.1Q tagging is on. When the phone displays both
messages alternately, access to local programming procedures is not disabled or
restricted. Finally, the phone displays the third message if 802.1Q tagging is off and
access to local programming procedures is disabled or restricted.
6. The system determines the DHCP protocol and the applicable parameters that are
enabled.
The DHCP server provides the IP addresses for the following hardware:
• The phone
• The HTTP/HTTPS server
• The TN799C or D Control-LAN (C-LAN) circuit pack on the media server
7. Using the list of gateway IP addresses provided by the DHCP server, the phone
performs a router check. The phone cycles through the gateway IP addresses with
ARPs or pings until it receives a response. When the router is located, the router
processes the received LLDP TLVs. Then the HTTP process starts.
8. While the IP phone connects to the HTTP server, the phone displays one of the
following messages:
HTTP: n ipadd
where n is the number of the IP address obtained from the HTTP server and ipadd
is the IP address.
9. When connected, the phone looks for an upgrade script file.
