Appendix E. Using the Optional
Modem Feature
E.1 Background
The modem option allows the ServSwitch to act as an Internet connection server
that increases security and flexibility when connecting with the managed
computers. Unlike the TCP/IP connection used with the standard Web
configuration and VNC clients, the modem creates a one-to-one connection
between the ServSwitch and the computer you are using to manage your network.
This connection is essentially private, since it bypasses the public Internet
completely. This option requires both an external modem (most standard
connection protocols are supported) and a dedicated phone line that can be
connected to the modem for external access. While it is technically possible to use
the modem feature through some PBX systems, this increases the connection’s
complexity and reduces its performance. For clarity, the instructions presented
here assume that the modem is connected to a typical POTS (plain old telephone
system) line that is not routed through a phone management system or shared
with other devices. If you want to use this feature through a PBX system, you might
need additional support from your telecom services provider.
E.2 Connecting a Modem
The ServSwitch works with virtually any Hayes
®
compatible modem that recognizes
the standard AT command set. Some modem manufacturers offer “enterprise”
modems that include technology to improve the connections’ stability. To
determine whether or not you need this type of modem, ask yourself:
1. Is the modem connection mission-critical?
2. Will your telecom infrastructure support such a modem?
3. Will your budget provide enough money for a higher-quality modem?
