Selecting Devices for Remote Users

Telecommuters and mobile users who access the central-site network for fewer than 2 hours per day can use an analog modem. Most laptop and desktop computers ship with a built-in analog modem. When selecting computers for remote users who will use modems, research the performance and functionality of the built-in modem. Some modems are notoriously unreliable, especially when connecting to modems of a different brand or connecting to certain types of services. Read articles in trade magazines and on the web to ensure that you select reliable modems with few interoperability problems, high throughput, low latency, and support for advanced features, such as compression and error correction.

For customers who want higher speeds than an analog modem can offer, remote access can be accomplished with a cable or DSL modem. The most important consideration when selecting a cable or DSL modem is that the modem must interoperate with the provider's equipment. In some cases, the provider supplies the modem to avoid problems. In other cases, the provider supplies a list of products or standards that must be supported in a modem purchased by the end user, such as the Data Over Cable Service Interface Specification (DOCSIS) for cable modems in the United States. For customers who need to connect more than just one user, a router that includes a cable or DSL modem or support for ISDN is appropriate.

Criteria for selecting a router for remote sites include the following:

• Security and VPN features

• Reliability
