The Digital Lightwave ASA 312 Network Information Computer is a portable analyzer engineered for verification and qualification of telecommunications networks across DS0 through OC-48c protocols. It delivers simultaneous and independent testing of T-Carrier, SONET, and ATM signals—consolidating multiple traditional test sets into a single modular platform. The instrument features a 9.5-inch color touch-screen GUI with remote control capability, built-in optical and electrical measurements, and SONET through-mode operation with overhead manipulation. Its flexible architecture supports field installation, monitoring, and maintenance workflows across evolving network environments.
