5. Is data transfer failing on one of the T1/E1 ports?
YES
• Verify the local T1/E1 connection at the local converter by starting a
local loop-back at the local converter:
- HW mode: set the local converter to T1/E1 loop-back (see page 4).
- SW mode: enter the local T1/E1 loop-back command at the local
converter.
• Use a bit error test unit to run a bit error test.
• Verify the remote T1/E1 connection at the local converter by starting a
remote loop-back at the local converter:
- SW mode: enter the remote T1/E1 loop-back command at the local
converter. (HW mode is not available.)
• Use a bit error test unit to run a bit error test.
• Verify the remote T1/E1 connection at the remote converter by starting a
remote loop-back at the remote converter:
- SW mode: enter the remote T1/E1 loop-back command at the remote
converter. (HW mode is not available.)
• Use a bit error test unit to run a bit error test.
• Verify the local T1/E1 connection at the remote converter by starting a
local loop-back at the remote converter:
- HW mode: set the remote converter to T1/E1 loop-back (see page 4).
- SW mode: enter the local T1/E1 loop-back command at the remote
converter.
• Use a bit error test unit to run a bit error test.

6. Is data transfer failing on the fiber port?
YES
• Verify the local fiber connection by starting a remote fiber loop-back:
- HW mode: set the remote converter to fiber loop-back (see page 7).
- SW mode: enter the remote fiber loop-back command.
• Use a bit error test unit to run a bit error test.
• Verify the remote fiber connection by starting a local fiber loop-back:
- HW mode: set the local converter to fiber loop-back (see page 7).
- SW mode: enter the remote fiber loop-back command.
• Use a bit error test unit to run a bit error test.
