ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

You can configure the dialer and test options if you wish. However, if you are using SW56, the Router will act as a dialer.

D.6.2 ADTRAN 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:
