28、C. 20006 PRICE: Please refer to the current Catalog of EIA 21 as 29 35 3l P P 31 35 s EIA TSB5O 73 = 3234600 0505509 287 W TSBSO User Interface for Authentication Key Entry 2.1.4 User Programming the Authentication Key The user may hit “D” to leave programming mode at any time. The mobile station sh
29、aii leave programming mode after a reasonable period of inactivity. When a user has reached the authentication key programming mode and scrolled to the appropriate MIN, the user may prow the authentication key by pressing the six to twenty six digit number provided by the der. The display shall show
30、 the digits of the ented number as the user is in the process of keying in the complete number. If the user makes a mistake he may clear all or part of the entered number by using the “clear” button. When the complete digit sequence has been keyed, the user shall press “store“. “store” to store the
31、number. At this point the mobile station shall validate the authentication key based on the check sum. If the key is valid, the display shall provide positive acknowledgment, such as the word “OK”, and the phone shall return to its nod operating mode. If the key is invalid, the display shall provide
32、 negative feedback, such as the word “invalid”. At this point the user shall re-enter the number and continue the process until the authentication key is stored correctly. 2.1.5 Programming the Authentication Key at Installation Mobile stations may also be programmable at the time of installation th
33、rough the normal NAM programming mode. Manufacturers may implement this programming capability however they see fit. There is no need for a user interface standard in this area because it is presumed that NAM programming will be done by a qualified technician with access to the manufacturers instail
34、ation and service directions. Mobile stations shall allow NAM programming to be completed without entering an authentication key, in order to allow carriers to implement user programming programs. Mobile stations without displays or the required keys for user programming shall provide means for prog
35、ramming the A-key at the time of installation. 2.2 Revising the Authentication Key New Authentication Keys Overwrite Old From time to time the authentication key in a mobile station may require revision. if a new key is required, it would be entered using the same process as described above, and sha
36、ll overwrite the existing authentication key in the mobile stations memory. 2.3 Access to the Authentication Kev No Access to the Authentication Key Once an authentication key is entered, it may not, under any circumstances or in any mode of operation, be viewed through a mobile stations display or through any device attached to the mobile station. This includes the authentication key and NAM programming modes and any test modes as well as normal operation. Page 2
