connection must be made via suitable protective devices (IP Office Barrier Box) at each end and via each building

• REN: 2
• Off-Hook Current: 25mA.
• Ring Voltage: 40V rms.
• Minimum Wire Size: AWG 26.
• Maximum Cable Length:
• AWG26: 0.5km / 1640 feet.

Except on some older equipment, these ports do not include a ringing capacitor. Therefore for connection to 4-wire
analog phones where this is a requirement (typically the United Kingdom and New Zealand), connection should be via a
Master socket containing ringing capacitors. On some older Small Office Edition, IP403 and IP400 Phone V1 modules,
pins 2 and 6 are internally connected via ringing capacitors.
Structured Cabling Line Cord
This is an RJ45 to RJ11 cable suitable for connection from a structured cabling system RJ45 port to a DS phone. It can
also be used for two-wire analog phone extensions.
