Page 66 - Port Safety Classification Technical Data
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:
Port Name Port Description Port Classification
PRI port PRI ISDN connection (NET) TNV (Operating within the limits of SELV)
BRI ports BRI ISDN connection (NET) TNV (Operating within the limits of SELV)
Analog ports Two wire analog trunk TNV3
Power fail ports Two wire analog trunk TNV3
DTE port Async Data connection. SELV
Telephone Ports Telephone Extension ports TNV2
WAN port WAN connection (NET). SELV
LAN ports 10/100 BaseT attachment to LAN. SELV
Expansion ports Expansion Module connector. SELV
Audio port Connector for Music on Hold. SELV
External Control port Connector for Controlling Ancillary circuits. SELV
DC Input port Connector for DC input power. SELV
Interconnection circuits shall be selected to provide continued conformance with the requirements of
EN 609050:1992/A3:1995 clause 2.3 for SELV circuits and with the requirements of clause 6 for TNV
circuits, after connections between equipment.
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.
