Getting Started The DEFINITY ® Remote Port Security Device (RPSD) is a single line dial-up port protection system that prevents unauthorized access to a host resource. Host resource dial-up ports, called “subscribers,” are protected by the installation of the RPSD Lock hardware unit on the analog interface channel leading to the subscriber por[...]

The RPSD system protects a port in the following manner: a call into the channel to the protected host activates the RPSD Lock. Without involving the protected host resource or its associated modem, the RPSD Lock performs a verification of the caller’s identity through a set of communications with the RPSD Key using DTMF signaling. This process i[...]

The RPSD Lock device is approximately the size of a modem and is connected between the PBX modem and the Central Office (CO) line. The RPSD Key device is of similar size and is connected between the client’s (caller’s) modem and CO line. See Figure 1-2. FIGURE 1-2 RPSD Lock and Key Configuration In Figure 1-2, the term “AT&T Remote Operat[...]

Room Layout/Environment While the location of the RPSD Lock is not critical to its function, it is best if the Lock is kept in an equipment cabinet near the PBX modem. This helps protect the Lock against dust and other precipitate, as well as protecting against physical damaging from being knocked to the floor or having things dropped on it. Altern[...]

Location of Administration Terminal or Printer For the purposes of installation, it is simplest if the RPSD Lock or Key administration terminal or printer is co-located with the RPSD Lock or Key. However, this is not always possible. In the event that the terminal or printer must be located at some distance from the RPSD Lock or Key (in another roo[...]

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 ter[...]

RPSD Power Monitor Adapter The Power Monitor Adapter (PMA) (Comcode 406453662) provides an installation option that allows you to control the behavior of the RPSD during power failure conditions. In the event of a unit failure or a power failure, the RPSD is designed to block incoming and outgoing calls to the port, protecting the port against unau[...]

A second pair of RJ11 port connections may be installed for simple bypass of the RPSD Lock. To bypass the Lock, the modular connection cords are removed from the RPSD Lock Telco and Subscriber ports and connected to the bypass connection block, which connects the line directly.
