Components that can cause an attendant console fault are:

• the console power supply
• the building wiring
• the cross-connect from the console to the line circuit
• the unit on the peripheral line circuit card
• the peripheral line circuit card
• the ringing generator
• the cabinet power supply
If more than one attendant console is affected, look for connections such as:
• they are on the same line circuit card
• there is a problem with ringing or tones
