Remote Access Server Port Speed Indicates DTE Rate

Remote Access Service (RAS) for Windows NT Advanced Server does not provide the Data Communications Equipment (DCE) link speed in the RAS Admin User Interface. If you select Port Status, you will see a field for "Port Speed [bps]." This value indicates only the Data Terminal Equipment (DTE) rate (bps, or bits per second, between serial port and modem). It does not adjust for the DCE link speed (bps between two modems).

For example, if your DTE rate is set for 38,400 bps and a client dials in at 2400, your modems will connect and operate at 2400. Your Port Speed will still show 38,400. The client's port status may show 2400 if the initial bps was specified as 2400.

This behavior is by design. Not all the modems supported by RAS will report the DCE link speed in their CONNECT response. However, they all can be configured to report their DTE rate.

Future versions of RAS will provide a way to report the DCE link speed to system administrators.
