DTRAN ISU 128
The Adtran ISU 128 provides service over a leased digital network. ISDN network termination is built
into the ISU 128, eliminating the need for an NT1.
Connect the Sync Router to the V.35 interface, and set the DIP switches to V.35 (both should be UP).
Before setting up the equipment, verify your operating mode. The Router Sync+ supports the following:
• for a 64K line: CLEAR CHANNEL SYNC or BONDING SYNC
• for a 56K line: CLEAR CHANNEL SYNC or BONDING SYNC
• for a LEASED 56K: CLEAR CHANNEL SYNC
• for a LEASED 64K: CLEAR CHANNEL SYNC
• BONDING: Bandwidth ON Demand.
• CLEAR CHANNEL: The entire channel (line) is provided to the Sync Router without regard to data
format or protocol.
Use the front-panel keypad to configure the ISU 128 as follows:
Network options:
The network options depend upon whether or not you are using a leased line or a SW56. Configure the
