3. 67 A Connecting a Modem The Digital KVM via IP will work with virtually any Hayes compatible modem that recognizes the standard AT command set Some modem manufacturers offer enterprise grade modem products at a premium price that include technology to improve the stability of connections whether this type of product would be beneficial to your application depends on whether you consider the modem connection to be mission critical the quality of your telecom infrastructure and your budget for implementing this solution The model of modem attached is essentially transparent to the Digital KVM via IP It is important to note that modems that offer 56K or 56 000 bps connections often achieve connection speeds that are far lower than their maximum capabilities Given the limitations of telecom infrastructure many locations have yet to implement fully digital switching technology and still rely on older analog technology for some segments the maximum upstream transfer rate is limited to a maximum of 33 600 bps between two modems the downstream rate is often within a similar range for a typical connection Therefore speeds below 56 000 bps do not indicate a problem with the modem or the but simply reflect the line conditions at the time the connection is made The SERIAL port on the rear panel must be used for the modem connection It requires the use of a null modem serial cable Place the modem near the Digital K
