Abstract
To provide a graphic user interface, supported by HTML or Java script, to a personal computer (102) for the control of SONET/SDH network elements (106), an RS-232 port of a PC is used to establish a PPP session to a remote access server, RAS (122). The network element (106) is therefore configured to imitate a modem, and to route PPP packets into its related management system across an optical ring (12). The management system may include an intermediate network manager (120) and a DHCP server (124). Once legitimacy of the PC is established through the IP session, the PC is provided with an IP address to invoke the PC's IP stack. Subsequently, IP is communicated across the PPP session, with the RAS (120) configured to terminate the PPP session and forward IP packets into an IP network (128). IP packets (131), received at a web server (140), are converted into command line interface (CLI) messages 135 and are sent directly to the network manager (120) within an IP packet. The network manager (120) terminated the IP packet and re-packages the CLI messages into an optical carrier format (140) for relay to an addressed network element (106). The addressed network element (106), which is…
