Installation

After unpacking the unit, immediately inspect it for possible shipping damage. If damage is discovered, file a claim immedi- ately with the shipping carrier, then contact ADTRAN Technical Support.

Each ISU 2x64 is provided with an eight-foot power cord termi- nated by a three-prong plug which connects to a grounded power receptacle.

ADTRAN ISU 2x64 part numbers 1200051L1, 1200051L2, and 1200051L5 require a grounded 115 VAC, 60 Hz receptacle for power.

ADTRAN ISU 2x64 part numbers 1200051L3, 1200051L4 and 1200051L6 require a 230 VAC, 50 Hz receptacle for power.

NETWORK CONNECTION

An eight-pin RJ-45 modular jack on the rear panel of the ISU 2x64 allows connection to ISDN Basic Rate service provided by the telephone company or to a leased type of service. This leased ser- vice can be dedicated 2B1Q data service or a nailed-up circuit that provides a dedicated connection between end points such as a limited distance modem or LAD circuit.

If using ISU 2x64, part number 1200051L1 or 1200051L3, connect the telephone company provided ISDN Basic Rate U-Interface to the RJ-45 connector marked ISDN IFC. An external NT1 is not needed in this configuration.
