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 test-
ing 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, – De-
cember 1990) and T1.403–1989 (Carrier to Carrier In-
stallation – DS1 Metallic Interface). Applications in-
clude Channel Service Units and similar equipment that
requires a fully protected interface.
