DESCRIPTION

The DS2290 T1 Isolation Stik provides all the surge and isolation protection that is necessary to connect a piece of equipment to a T1 line. It offers a function similar to that provided by a Data Access Arrangement (DAA) when a modem is connected to a phone line. The DS2290 is FCC Part 68 pre–registered so the user can connect equipment to T1 lines without any further testing or qualification. It contains onboard waveshaping circuitry that creates transmit pulses meeting the latest T1 specifications including TR 62411 (Accunet* T1.5 Service Description and Interface Specifications, – December 1990) and T1.403–1989 (Carrier to Carrier Installation – DS1 Metallic Interface). Applications include Channel Service Units and similar equipment that requires a fully protected interface.
