Regulatory information 21
Installation and Maintenance Guide
Enhanced 911 configuration
Radio-frequency interference
Telecommunication registration
BCM50 equipment meets all applicable requirements of both Industry Canada CS-03 and US
Federal Communications Commission (FCC) Part 68 and has been registered under files Industry
Canada 332D-5980A and FCC US: AB6KF15B20705 (key system), US: AB6MF15B20706
(hybrid system), and US: AB6PF15B23740 (PBX system). Connection of the BCM50 telephone
system to the nationwide telecommunications network is made through a standard network
interface jack that you can order from your local telecommunications company. This type of
customer-provided equipment cannot be used on party lines or coin lines.
Caution: Only qualified persons should service the system.
The installation and service of this hardware is to be performed only by service personnel
having appropriate training and experience necessary to be aware of hazards to which they
are exposed in performing a task and of measures to minimize the danger to themselves or
other persons.
Electrical shock hazards from the telecommunication network and AC mains are possible
with this equipment. To minimize risk to service personnel and users, the BCM50 system
must be connected to an outlet with a third-wire ground.
Service personnel must be alert to the possibility of high leakage currents becoming
available on metal system surfaces during power line fault events near network lines.
These leakage currents normally safely flow to Protective Earth ground through the power
cord. Therefore, it is mandatory that connection to an earthed outlet is performed first and
removed last when cabling to the unit. Specifically, operations requiring the unit to be
powered down must have the network connections (central office lines) removed first.
Warning:
Local, state and federal requirements for Emergency 911 services support by Customer
Premises Equipment vary. Consult your telecommunication service provider regarding
compliance with applicable laws and regulations.
Warning: Equipment generates RF energy.
This equipment generates, uses, and can radiate radio-frequency energy. If not installed
and used in accordance with the installation manual, it may cause interference to radio
communications. It has been tested and found to comply with the limits for a Class A
computing device pursuant to Part 15 of the FCC Rules and with ICES.003, CLASS A
Canadian EMI Requirements. Operation of this equipment in a residential area is likely to
cause interference, in which case the user, at his or her own expense, will be required to
take whatever measures may be required to correct the interference.
