3Com Router 5000 and Router 6000 v2.41Module GuideChapter 3Multifunctional Interface Modules (Router 5000)3-22Asynchronous serial interface is generally used as dialing port and connected to amodem or a Terminal Adapter (TA). In this case, regardless of the operating mode ofthe device, only an appropriate baud rate for the interface needs to be selected.Serial interface is generally used for the direct connection to such a device as DDN,frame relay, or X.25 switch.3.6.2 Interface AttributesThe interface attributes of Router 4-Port Serial MIM are given in the following table:Table 3-14 Interface attributes of Router 4-Port Serial MIMDescriptionAttributeSynchronous AsynchronousConnector DB100 (Router 4-Port Serial MIM)Number ofconnectors 1 (Router 4-Port Serial MIM)V.24 V.35Interface standardand operatingmodeDTEDCE DTE DCERS232Minimum baudrate(bps)1200 1200 1200 300Maximum baudrate(bps)64 k 4.096 M 2.048 M 115.2CableV.24 (RS232) DTE cableV.24 (RS232) DCE cableV.35 DTE cableV.35 DCE cableRouter 4-Port Serial MIM conversion cable (Router 4-Port Serial MIM)ServicessupportedDDN leased lineTerminal access serviceDialup through modemBackupAsync leased lineDumb terminal access
