Revising Allowed Lists may affect other features, including Auto Dial, Automatic Route Selection (ARS), calling restrictions, Conference, Directories, Forward and Follow Me, Night Service, personal lines, Remote Access, Speed Dial, and Toll Type. For more information, see the Feature Reference.

NOTE:

When Allowed Lists are used in conjunction with Remote Access to restrict calls made through the system from remote locations, the Allowed Lists can be assigned to either a specific barrier code (password) or to specific types of remote access trunks (for example, all tie/DID trunks).

In Release 3.1 and later systems, star codes may be included in Allowed and Disallowed Lists. In these releases, dialed star codes are ignored by ARS for routing calls. Star codes are provided by the central office (CO) to allow the use of special features (for example, in many areas *70 turns off a call-waiting feature provided by the central office). In Release 3.0 and earlier systems, the star code digits were processed as dialed digits by ARS, Allowed Lists, Disallowed Lists, and calling restrictions. Therefore, the actual called party number was not properly processed when a star code was entered.

Release 3.1 and later systems permit system managers to include star codes in Allowed and Disallowed Lists. If a star code is allowed, the digits following the star code are checked normally by Allowed/Disallowed Lists, calling restrictions, and ARS.

The MERLIN LEGEND Communications System Release 3.1 and later observes these Bellcore standards for star codes:

■Only 2- or 3-digit star codes are recognized. Two-digit star codes must begin with 1, 4, 5, 6, 7, 8 or 9. Three-digit star codes must begin with a 2 or a 3.

■The star code or codes must come at the beginning of the string of digits dialed, not at the end or in the middle.

■Multiple leading star codes are allowed. For example, *67*705551212 is recognized correctly, but in 5551212*67*705553131 the stars are ignored.

Valid Entries

6 digits for each number (an area code plus an exchange, or 6 digits with a leading 1, where required)

Asterisk (*, Release 3.1 and later systems only) preceding a maximum of one leading star code per entry

10 numbers for each list (numbered 0 through 9)

8 lists for each system (numbered 0 through 7)
