RPSD Key Use for details on using this command with the RPSD Key 2 A Installation Hardware Components When you order the RPSD Lock device you receive the Lock power supply a 7 foot cable with modular connectors on each end and a 14 foot cable with modular connectors on each end If any other cables or connectors are required they must be ordered separately In addition any peripheral devices such as the administration terminal or printer are customer supplied A PBX and modem are assumed to be at the customer site already Note Although the printer is not essential to system operation it is highly recommended that a printer be dedicated to the RPSD Lock Because the System Activity Log is limited to storing sixty messages the only means of retaining a more permanent record of system activity is to either install a dedicated printer for the RPSD Lock or to save all messages from the Lock to disc With regard to RPSD Key devices the AT amp T entities which require access to the PBX already have the Keys that they need Any additional RPSD Keys for customer use must be ordered separately Each of the hardware components both supplied and otherwise and their requirements are described in the following sections RPSD Lock The RPSD Lock is 5 75 inches wide by 9 5 inches long by 1 75 inches high The RPSD Lock has seven LEDs on the front panel and four ports on the back panel For a detailed description of the front panel L

D Lock performs a verification of the caller s identity through a set of communications with the RPSD Key using DTMF signaling This process is described in the following procedure and is illustrated by Figure 1 1 1 The Lock installed on tip and ring on the network side of any modem or protected host resource answers the incoming call 2 The Lock sends the caller a polling tone If the calling party has an RPSD Key the Key responds with its User ID If there is no Key on the calling end the Lock terminates the call 3 The Lock must recognize the Key s User ID it must be previously initialized with all valid Keys if not the Lock terminates the call 4 Using an algorithm governed by ANSI DES standards the Lock generates a random 10 digit value known as the dynamic challenge for which there are 10 billion possible values Using a secret encryption key that is uniquely associated with the calling RPSD Key s User ID the Lock puts the value through the encryption process and encrypts it 5 Itstores the encrypted expected value and sends the dynamic challenge to the Key 6 The Key repeats the encryption process and calculates the necessary response The Key transmits the expected value to the Lock 7 The Lock authenticates the response by comparing it to the expected value it calculated and stored If the Lock receives the precise value it expects it generates ringing and sends the call on to the protected resource The en
