Managed External Modem; The MEM-336 Managed External Modem is ideal for applications that require a fail-safe, desktop modem. In order to ensure constant, reliable service, the MEM-336 always resets itself to answer on the specified number of rings and is set to a fixed baud rate at the modem port. This makes the MEM an ideal solution for remote sites that require "must answer" modem communication. The MEM is also extremely well suited for connection to devices that cannot send "AT" setup strings; the MEM configures itself on power-up, without the need for external AT configuration commands.
