Port Safety Classification
The Avaya IP Office systems have the following ports:
• Expansion ports
• 10/100 BaseT LAN ports
• Telephone ports which are either DT (A-Law encoding) or DS (µ-Law encoding)
• ISDN ports
• Analog ports
• Power Fail ports
• WAN ports
• DTE ports
• Audio I/P port
• DC Power Input port
• External Control port
These Ports are classified as follows:

Compliance with FCC Rules
Transmit and Receive Gain Settings for PRI/T1 and Analog Ports
The Gain settings are password controlled for use by qualified installation personnel only
and must not be made available to the end user. The default gain settings of 0dB ensures
compliance with FCC part 68 section 68.308(b)(5) and TIA/EIA-IS-968 Section 4.5.2.5.
“Through transmission amplification from ports for the connection of separately registered
equipment or from other network connection ports”. Gain setting adjustment by unqualified
personnel may result in violation of the FCC rules. Qualified personnel may adjust gain
settings above these levels only where:
1. Measurement is made to ensure that the power levels sent to line at each network
interface connected does not exceed the maximum levels specified in FCC part 68
section 68.308(b) and TIA/EIA-IS-968 Section 4.5 for that specific interface type.
2. Where gain adjustment away from the default values are made, precautions should be
taken to ensure that the connection of terminal equipment is controlled by qualified
installation personnel.
