The Trunk Data Module (TDM)
Issue 11 December 1999
21-61
The TDM can serve as part of a conversion resource for modem pooling. The
conversion resource performs the analog-to-digital and digital-to-analog
conversions that allow the analog and DCP data endpoints to communicate. A
single conversion resource consists of a modem and a TDM connected at the
RS-232-C interface.
NOTE:
The TDM can no longer be ordered. It has been replaced by the MTDM.
