Central Management

Central management of all VCN AC ports is performed through LMA port 1 (the leftmost LMA of the VCN AC) or Telnet. The user sends commands to the management agent in card slot 1 through a locally attached management terminal or remotely through a Telnet session. The management agent controls the communications ports by sending them commands and receiving responses through a proprietary management message set. The user monitors and manages the VCN AC from a single point and can view status and statistical information on the VCN AP-VCN AC lines as well as perform certain configurational options such as setting full or half duplex.

Remote Management

An VCN AC can be centrally and remotely managed via Telnet. Instead of attaching a terminal to the LMA, the user connects to the VCN AC management agent (in the leftmost card slot) though the Telnet protocol over the Internet. Access is password protected. Messages in the management user interface are carried in the VCN AC card slot 1 LAN port, which is connected by an Ethernet link to an Ethernet switch. It is not neccesary for LMA port 1 to be used.
