Introduction

392xPlus Operational Modes

The 392xPlus operational modes determine how your modem performs in various applications. These operational modes are determined by your modem model and the selected configuration options.

There are two operational modes:

•Singleport mode. Operates on both the singleport and multiport modems. Singleport mode is the only operational mode for the singleport modem. For the multiport modem, it is in effect when the MUX mode configuration option is set to Disable. The Singleport mode only supports one port (DTE 1).

•Multiport operational mode. Operates only on the multiport modems. Multiport mode is in effect when the MUX mode configuration option is set to TDM/MSD or DTE_Bridge. It supports from one to four ports (DTE 1±4), depending on how the modem is further configured.

Using Table 1-1, identify your modem's operational mode based on the 392xPlus modem model and its selected MUX mode configuration option.

Table 1-1
