■Seven-Digit Password for SPM

Release 4.0 has increased system security by requiring a 7-digit password for system managers or technicians who use System Programming and Maintenance (SPM) to perform programming or the Trunk Test procedure. This password is for use in addition to a remote access barrier code.

Release 3.1 Enhancements (March 1996)

Release 3.1 includes all Release 3.0 functionality, plus the enhancements listed below.

■Call Restriction Checking for Star Codes

Beginning with Release 3.1, a system manager can add star (*) codes to Allowed and Disallowed Lists to help prevent toll fraud. Star codes, typically dialed before an outgoing call, enable telephone users to obtain special services provided by the central office. For example, in many areas, a telephone user can dial *67 before a telephone number to disable central office-supplied caller identification at the receiving party’s telephone. You must contract with your telephone service provider to have these codes activated.

When users dial star codes, the system’s calling restrictions determine whether the codes are allowed. If they are allowed, the system’s calling restrictions are reset, and the remaining digits that the users dial are checked against the calling restrictions.

■Trunk-to-Trunk Transfer Set for Each Extension

This enhancement to the Transfer feature enables the system manager to allow or disallow trunk-to-trunk transfer on a per- extension basis. In Release 3.1 and later systems, the default setting for all extensions is restricted.

■Programmable Second Dial Tone Timer

The system manager can assign a second dial tone timer to lines/trunks, in order to help prevent toll fraud (for example, when star codes are used). After receiving certain digits dialed by a user, the central office may provide a second dial tone, prompting the user to enter more digits. If this second dial tone is delayed, and the user dials digits before the central office provides the second dial tone, there is a risk of toll fraud or misrouting the call. The second dial tone timer enables the system manager to make sure that the central office is ready to receive more digits from the caller.

■Security Enhancements

The sections below outline security measures that are implemented in Release 3.1 and later systems.
