The Digital Loggers DL-PRI is a T1 PRI USB audio logger that captures audio from T1 lines through a transparent Hi-Z connection, eliminating the need for channel banks. It supports all common T1 formats, including SF, ESF, B8Zs, AMI, Japanese CRC, and FT1, and can combine data from two T1s in full-duplex, 24-channel mode. This logger offers USB plug-and-play operation and is compatible with Windows 2003, 2008, Vista, and XP.
