Message Logging Systems

Message Logging Systems

Paging Message Logging software collects data decoded off-the-air and sends the data to the logging server. Logs can be used to prove messages were actual transmitted and were capable of being received without error. The log scanning option can detect specified message content and notify system operator of alarms or other action to be taken. Requires PDR-4 or ipBSC with internal PDR activated.

Paging Data Receivers

The PDR-4 Paging Data Receiver is a multi-function paging data receiver/off air decoder/pager for receiving paged messages and processing them in a variety of ways.

The Prism-IPX ipBSC has a PDR built-in so the data is sent to the Prism server Dispatcher archive and then on to the ECHO software for logging and reporting.

Message Logging Software

The Prism-IPX ECHO software is designed to receive and log paging messages using Prism-IPX Paging Data Receivers (PDR). ECHO receives decoded paging messages from PDRs and logs the information showing proof of transmission over the air verifying the paging system is working. ECHO is positive proof that the paging system is working. For verification that a page was actually transmitted the ECHO log can easily be searched for the message.

The Prism-IPX ECHO software can send periodic test pages with unique message content so when the off-the-air data is decoded ECHO searches for these messages. If a message(s) is missing ECHO can send a notification via any of several different protocols to a designated location(s) calling attention to the problem. Notification can be sent to your paging system paging, email or smartphones or even other paging systems. Notifications are often sent to technical staff so they quickly respond to a system problem.
