  Condition: For Parts or Not Working
  This Adtran DSU II All Rate Data Service Unit is being sold AS-IS for parts or repair. The unit is missing its fuse and fuse cap (rated 0.1A Slo-Blo Type 3AG), and has not been tested or verified functional. A fixed AC power cable is attached. The chassis and front panel appear cosmetically clean with no visible cracks or major damage. All rear interface ports — V.35 PRI Sync, ASYNC, PRI Sync Subrate, and Telco — are present and appear intact. Due to the missing fuse and fuse cap, we cannot confirm whether this unit powers on or operates correctly, so it is offered strictly as-is.
