3Com Router 5000 and Router 6000 v2.41 Module Guide Chapter 1 Overview The router series supports hot swapping. Thus, you can remove or install FICs when the router is running without disconnecting the power supply. But before that, you must first execute the remove slot command; otherwise, unknown errors might occur. When you replace the removed FICs, you do not need to execute the undo remove slot command however.

It supports: Transmission/Receiving and handling of synchronous and asynchronous serial z data streams; Different operating modes, such as V.24/V.
PAGE 21
3Com Router 5000 and Router 6000 v2.41 Module Guide Chapter 2 Smart Interface Cards Caution: The baud rate cannot exceed 64 kbps if V.24 cable is used and the interface operates in synchronous mode. II. DTE and DCE The synchronous serial interface supports both DTE (Data Terminal Equipment) and DCE (Data Circuit-terminating Equipment) operating modes. Given that two devices are directly connected, if one operates in the DTE mode, the other will operate in the DCE mode.

3Com Router 5000 and Router 6000 v2.41 Module Guide Chapter 3 Multifunctional Interface Modules (Router 5000) The synchronous serial interface can work in either DTE or DCE mode. Two directly connected devices must work as DTE and DCE respectively. The DCE provides clock synchronization and specifies the communication rate, whereas the DTE accepts clock synchronization and communicates at the specified rate. The router normally works as a DTE.
