What is the significance of the PortMaster 4s hot-standby modem cards?
A. They help maximize uptime: the PortMaster 4 has 98 modems in each of its modem pools to support 96 connections. If a modem fails, the PortMaster 4 automatically detects this, takes that modem out of service, assigns one of the extra modems, and informs the operator. Competing products do not have these hot stand-by modems.
