AudioCodes MP-112R - FXO Line Testing

User's Manual 7. Troubleshooting
Version 6.6 151 MediaPack Series
• 10 = Resistance Ring-Ground [Ohm]
• 11 = Capacity Tip-Ring [F]
• 12 = Capacity Tip-Ground [F]
• 13 = Capacity Ring-Ground [F]
• 14 = AC Voltage Tip-Ring [V]
• 15 = AC Voltage Tip-Ground [V]
• 16 = AC Voltage Ring-Ground [V]
• 17 = All the above
Notes:
• Use the Analog Line testing mechanism only for monitoring and never
when there are calls in progress.
• Line electrical measurements are supported only on certain MP-124
hardware assemblies. For more information, contact your AudioCodes'
sales representative.
