Pulse dialing for a call

If your external telephone lines use pulse dialing, you can switch to tone dialing by pressing £ after selecting the line. Tone dialing allows your telephone to communicate with devices and services that respond to tone signals, such as automatic switchboards, and fax or answering machines.

Access your system from an external location

You can use the lines and some of the features of Business Communications Manager from outside the system. You can access the lines and some of the features over the public telephone network when away from the office, or you can call from another system, over a private network.

It is important to maintain the security of your system by limiting access to authorized users and limiting those users to the features they need.

For example, a sales representative out of the office needs to make long distance calls to the European office. Your system has a leased line to Europe with reduced transatlantic charges. You provide the sales representative with a Class of Service password that gives access to the transatlantic line. The sales representative can telephone into the system from a hotel, enter the Class of Service password, and use the leased transatlantic line to make calls.

Remote users can access system lines, line pools, the page feature, and remote administration (if enabled through Software Keys). The exact facilities available to you through remote access vary depending on how your installer set up your system.

Note: If the loop start line used for remote access is not supervised, auto-answer does not function and the caller hears ringing instead of a stuttered tone or the system dial tone.

Direct Inward System Access (DISA)

Control access to your system with direct inward system access (DISA). Access to your system from the public telephone network must be controlled with DISA. If your installer programs the line used for remote access to answer a call automatically and wait for a DISA internal number, callers hear a stuttered dial tone and must enter a Class of Service password before they are allowed into the system.

Class of Service (COS)

To control the level of telephone service a remote user can access, the installer can assign a remote filter and remote package to the line used for remote access. The remote filter limits the numbers dialed on the line, and the remote package limits the use of line pools and the page feature. To change the restrictions for the line, the user can enter their Class of Service password when the system answers with DISA, or dial the DISA internal number and enter their Class of Service password.
