Configuring the 7400D data module
The 7400D data module is a converted 7400A used for synchronous data
transmission (see Figure 16). It is a direct replacement for the MPDM. You
configure the 7400D just as you would a 7400A, except that there is no SET
INTERFACE option (the 7400D is an answer-only device that cannot originate
calls). It supports DCE mode only. DTE modem-pooling is not supported. The
PHONE and PORT2 connectors are not used.
The following table lists recommended settings for a typical installation. For the
configuration procedure, see the subsequent sections.
