Usually, however, it is because the worker needs frequent access to the corporate network to synchronize e-mail and schedules and to use the company's network resources. In this situation, a permanent high-speed connection may be required. This may mean using cable modem, ISDN, or DSL service, depending on what is available in your area. It may also mean that the telecommuter must install and maintain a firewall at his or her end of the connection, to keep data transfers secure. If you work for a large company, you may be required to connect to the company's network.
Some companies allow remote workers to access the Internet only through the company's proxy servers.
In this case, the company may install a high-speed connection for the worker, as described earlier. This may sound cumbersome, but the approach has many advantages. For example, the worker is always connected to the corporate mail system and can use the company's network servers just as easily as if he or she was sitting in a company office. No matter which approach best fits your needs, each one carries its own set of responsibilities. For example, the telecommuter is generally responsible for interacting with the local phone company or ISP, to ensure that installations and service are problem-free.
