Avaya 40DHB0002USCL Manuel D’Utilisation

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:

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. 

 

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.
