Local Management

The VCN AC enables local management of every communication port. Figure 5 shows the VCN AC front panel with the Local Management Access (LMA) ports uncovered. For every VCN AC communication port there is an LMA port. The LMA ports are for connecting ASCII terminals that provide the management interface. The user monitors and manages each communication card through a management terminal directly attached to the card LMA port. Line status information on the VCN AP-VCN AC connection is available.
