LANCOM Serial Adapter Kit

For "COM-port forwarding" via TCP

With the Serial Adapter Kit, analog lines in international networks can also be connected to your LANCOM devices with serial interfaces and used for remote maintenance purposes. External Analog or GSM modems (D-Sub9 / D-Sub25) are used as additional WAN interfaces via the serial interface and offer an alternative, highly available connection option via analog telephone lines or the mobile network – beyond the ISDN interface often integrated in Germany.


Internationally, analog telephone connections are just as common in the business world as the predominant ISDN connections in Germany. The operation of international networks thus places particular demands on remote maintenance options and for high-availability of the gateways and thus requires different interfaces than the ISDN common in Germany. Apart from conventional analog telephone lines, mobile telephone networks such as GSM or GPRS may, in certain cases, represent the only way of providing remote maintenance without broadband or other cabled access. In response to these requirements, most LANCOM models with a serial interface can be extended with an additional WAN interface with the use of analog modems, GSM or GPRS.
