port groups In the DTC 16TN and DTC 72MX, the ports are grouped into port groups. Each
port group has eight ports. The DTC 16TN has two port groups, and the DTC 72MX
has three port groups per board. Each port group can be modem or direct-connect. A
port group corresponds to a connector on a board of a DTC 72MX or to a connector
on a DTC 16TN.

RMP Remote Maintenance Protocol. HP proprietary protocol used in DTC management.
RS-232-C The Electronic Industries Association (EIA) Level 1 protocol specification that
defines electrical circuit functions for 25 connector pins. Hewlett-Packard provides
two implementations of this standard: a 3-pin version for direct connections up to a
distance of 15 meters (50 feet), and a version which makes use of additional circuits
and can be used for either modem or direct connections.
RS-423 The Electronic Industries Association (EIA) Level 1 protocol specification
implemented by HP in a 5-pin version which can be used for direct device
connection up to a distance of 1500 meters (4000 feet).
