9. Click the ‘RESET’ button and click ‘OK’ in the prompt; wait approx. 60 seconds and
refresh the Web page
10. Restore your PC’s IP address and Subnet Mask to their original values.
11. Using “Advanced Configuration” and “Protocol Management” screens you can modify all
H.323 and other Gateway parameters. Refer to Section 7.2 for detailed directions of
operating under Web management control.
12. Finally you can establish phone calls between phones connected to the Gateway ports
(for FXS Gateway) by dialing 101-108 numbers.
4.4 BootP and TFTP Procedures
If the Gateway IP address is known, you can use Web browser control for Gateway configuration
and provisioning. Otherwise, you can use BootP (or DHCP) and TFTP protocols for initialization
and software download.
Each time the MP-1xx Gateway is powered-on, it performs the standard BootP procedure.
If "DHCPEnable = 1" line is included in Gateway's ini file and if the BootP server was not found,
the Gateway initiates standard DHCP procedure to configure the Gateway network parameters
(IP address, Subnet mask and Default router address). If DHCP procedure is used, you also need
to find the new Gateway IP address allocated by DHCP server. Usually this information can be
provided by System Administrator or you can connect the MP-1xx to PC hyper terminal using RS-
232 cable and view the Gateway network settings after the Gateway is reset (see chapter 8.4).
If the BootP/DHCP server has not been found, the MP-1xx Gateway starts working from its
internal flash memory.
Usually the application software already resides in the MP-1xx flash memory; therefore there is
no need to use the BootP or TFTP procedure. Their download need only be used for changing
the MP-1xx configuration or for a new software upgrade.
The BootP Protocol enables the network administrators to manage the configuration of the MP-
1xx Media Gateway from a central configuration server - BootP/DHCP server.
The following RFCs (IETF Requests for Comment) describe BootP in detail: RFC 951, RFC 1542
and RFC 2132.
Downloading of the image file by the MP-1xx is performed using Trivial File Transfer Protocol
(TFTP). TFTP protocol is described in RFC 906 and RFC 1350.
Although DHCP and BootP servers are very similar in operation, the DHCP server includes some
differences that might prevent its operation with BootP clients. However, many DHCP servers,
such as Windows
™
NT DHCP server, are backward-compatible with BootP protocol and can be
used for MP-1xx configuration.
Note: The BootP server is normall
