Synchronous Trunk Record-Playback


GL’s Synchronous Trunk Record/Playback (or STRP) application has both Record and Playback features that permits the user to synchronously record any type of traffic (voice, digits, and tones) on multiple complete T1 or E1 lines (trunks) with accurate timestamp.  Playback of some or all of the recorded data permits the user to recreate the transmission exactly as it occurred.

The STRP application records the live T1 E1 traffic, and saves it to a file. The file naming convention is based on coordinated universal time (UTC) with the precision of 100 nano seconds intervals. UTC-based time is loosely defined as the current date and time of day in Greenwich, England.
