摘要： The present invention provides for a method of restricting access to authorized users of telephone service from a telephone at a particular location which telephone is accessible by more than one individual. The present invention provides for a method of activating a telephone line by entering a valid access code and deactivating the telephone line by entering a second valid code. Calls may not generally be placed from the telephone when the telephone line deactivated. Calls made from the telephone line after the telephone line has been activated by a valid access code will be attributed to the user associated with the access code. The present invention also provides for a method of routing calls which have been designated as escape codes or priority numbers although the telephone line is in a deactivated state. The present invention also provides a method for activating the telephone line by first entering a logon code followed by an access code which is associated with a user. The access codes may be further used to identify users for which toll calls are not permitted. If an authorized user's access code contains a toll restriction indicator, toll calls attempted by the authorized user when logged in under the user's access code will not be routed.

摘要翻译： 本发明提供了一种限制从特定位置处的电话到电话服务的授权用户的访问的方法，该电话可由多于一个的个人访问。 本发明提供一种通过输入有效的访问代码来激活电话线路的方法，并且通过输入第二有效码来停用电话线路。 当电话线路停用时，通话通常不能从电话中放出。 通过有效的访问代码激活电话线之后，从电话线进行的呼叫将归因于与访问代码相关联的用户。 本发明还提供了尽管电话线处于去激活状态的路由已经被指定为转义码或优先权号码的呼叫的方法。 本发明还提供了一种用于通过首先输入与用户相关联的访问代码的登录码来激活电话线的方法。 访问码可以进一步用于识别不允许长途呼叫的用户。 如果授权用户的访问代码包含长途限制指示器，则授权用户在用户访问代码下登录时尝试的长途呼叫将不被路由。
