Troubleshooting

The DSU/CSU is designed to provide you with trouble-free service. However,

Table 4-6 gives you some direction if a problem occurs.

For problems other than those listed in the table, please contact your service

representative.

Table 4-6. Troubleshooting (1 of 2)

Symptom Possible Cause Solutions

No power 1. The power module is not

securely attached.

2. The wall receptacle has

no power.

1. Check the power module

attachment.

2. Check the wall

receptacle power by

plugging in some

equipment that is known

to be working.

Power-Up Self-Test fails The DSU/CSU has

detected an internal

hardware failure.

Contact your service

representative.

Message LOS at

Network appears 1. Network cable problem.

2. No signal is being

transmitted at the

far-end.

3. Facility problem.

1. Check that the network

cable is securely

attached at both ends.

2. Check the far-end status.

3. Contact your facility

provider.

Message LOS at DTE

appears 1. 1.DTE Drop/Insert

(DSX-1) cable problem.

2. No signal being

transmitted from the

DTE.

1. Check that the DTE

Drop/Insert (DSX-1)

cable is securely

attached at both ends.

2. Check the DTE status.

Message OOF at

Network appears 1. Incompatible framing

format between the

network and the

DSU/CSU.

2. Network cabling

problem.

3. Facility problem.

1. Check that the framing

format for the network

interface is correct.

2. Check that the network

cable is securely

attached at both ends.

3. Contact your facility
