System Components: Physical Ports
10.12.13 PHONE (POT) Port
These ports are analog extension ports. On older IP Office units these ports were labeled as POT ports rather than PHONE
ports.
PHONE ports on Phone V1/V2 expansion modules can be connected to out-of-building extensions . If this is the case,
connection must be made via suitable protective devices (IP Office Barrier Box) at each end and via each building
primary protection. In addition the Phone module must be connected to a protective ground.
PHONE ports on IP Office control units must not be connected to out-of-building extensions.

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.
