TopServer-30

DESCRIPTION

The TopServer-30 gives service providers a highly scalable means of installing and adding dial-up ports. Each shelf can support 30 ports and unlimited number of shelves can be stacked and connected using a single network bus. All the connected dial-up servers are centrally managed by a host PC.  The system provides the two most important features sought by service providers: log-in security authentication, restrictions and accounting. Both operations are processed from the host PC using encrypted negotiations. The system incorporates several facilities to insure efficient and trouble-free operation. Each modem is equipped with a watchdog circuit that automatically resets the modem when it sense a hang-up. Each port has an off-hooking circuit to force the line into a busy state so that the central office rotary (ACD) can bypass the defective port and prevent it from blocking downstream lines. The system will also carry out a loopback test of all the ports at a given interval to check if the modem and lines are okay. Two power supplies can be installed for redundancy. The host PC management program will also check all the connected servers at a given interval. For further fault-tolerance, the system can utilize two simultaneous host PCs. The extensive monitoring and reporting provide the operator a tool for evaluating port performance and increasing overall efficiency. With a low per-port cost, the TopServer-30 offers a highly scalable and expandable platform. Together with its reliability, it is an ideal choice for a dial-up
