98 Using System featuresEnterprise Edge 2.0 Feature Programming Telephone Guide P0911589 Issue 03An example of how remote access works is a sales representative out of the officewho needs to make long distance calls to the European office. Your Enterprise Edgesystem has a leased line to Europe with reduced transatlantic charges. You providethe sales representative with a Class of Service password that gives access to thetransatlantic line. The sales representative can telephone into the Enterprise Edgesystem from a hotel, enter their Class of Service password, and use the leasedtransatlantic line to make calls.Remote users can access Enterprise Edge lines, line pools, the page feature, andremote administration (if enabled through Software Keys). The exact facilitiesavailable to you through remote access vary depending on how your installer set upyour system.Controlling access to your Enterprise Edge systemIt is important to maintain the security of your Enterprise Edge system by limitingaccess to authorized users and limiting those users to the features they need.Direct inward system access (DISA)Control access to your Enterprise Edge system with direct inward system access(DISA). Access to your Enterprise Edge system from the public telephone networkmust be controlled with DISA. If your installer programs the line used for remoteaccess to answer a call automatically and wait for a DISA internal number, callershear a stuttered dial tone and must enter a Class of Service password before they areallowed into the system.Class of Service (COS)To control the level of telephone service a remote user can access, the installer canassign a remote filter and remote package to the line used for remote access. Theremote filter limits the numbers dialed on the line, and the remote package limitsthe use of line pools and the page feature. To change the restrictions for the line, theuser 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.TipIf the loop start line used for remote access is not supervised, auto-answerdoes not function and the caller hears ringing instead of a stuttered tone or thesystem dial tone.Remote users can make long distance calls.Remember that a remote user can make long distance calls that are charged toyour company and can make page announcements in your office.
