Affidavit Requirements for Connection to Digital Services
• An affidavit is required to be given to the telephone company whenever digital
terminal equipment without encoded analog content and billing protection is
used to transmit digital signals containing encoded analog content which are
intended for eventual conversion into voice band analog signal and transmitted
on the network.
• The affidavit shall affirm that either no encoded analog content or billing informa-
tion is being transmitted or that the output of the device meets Part 68 encoded
analog content or billing protection specification.
• End user/customer will be responsible to file an affidavit with the local exchange
carrier when connecting unprotected CPE to a 1.544 Mbps or subrate digital ser-
vice.
• Until such time as subrate digital terminal equipment is registered for voice appli-
cations, the affidavit requirements for subrate services are waived.

Federal Communications Commission Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a Class A dig-
ital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in
a commercial environment. This equipment generates, uses, and can radiate radio fre-
quency energy and, if not installed and used in accordance with the instruction man-
ual, may cause harmful interference to radio frequencies. Operation of this equipment
in a residential area is likely to cause harmful interference in which case the user will
be required to correct the interference at his own expense.
Shielded cables must be used with this unit to ensure compliance with Class A FCC
limits.
Canadian Emissions Requirements
This digital apparatus does not exceed the Class A limits for radio noise emissions
from digital apparatus as set out in the interference-causing equipment standard enti-
tled “Digital Apparatus," ICES-003 of the Department of Communications.
Cet appareil nuerique respecte les limites de bruits radioelectriques applicables aux
appareils numeriques de Class A prescrites dans la norme sur le materiel brouilleur:
"Appareils Numeriques," NMB-003 edictee par le ministre des Communications.
Change or modifications to this unit not expressly approved by the party re-
sponsible for compliance could void the user’s authority to operate the equip-
ment.

Canadian Equipment Limitations
Notice: The Canadian Industry and Science Canada label identifies certified equip-
ment. This certification means that the equipment meets certain telecommunications
network protective, operational, and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be con-
nected to the facilities of the local telecommunications company. The equipment must
also be installed using an acceptable methods of connection. In some cases, the com-
pany’s inside wiring associated with a single line individual service may be extended
by means of a certified connector assembly (telephone extension cord). The customer
should be aware that compliance with the above limitations may not prevent degra-
dation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian mainte-
nance facility designated by the supplier. Any repairs or alterations made by the user
to this equipment, or equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of
the power utility, telephone lines and internal metallic water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.
The Load Number (LN) assigned to each terminal device denotes the percentage of
the total load to be connected to a telephone loop which is used by the device, to pre-
vent overloading. The termination on a loop may consist of any combination of
devices subject only to the requirement that the total of the Load Numbers of all
devices does not exceed 100.
Users should not attempt to make such connections themselves, but
should contract the appropriate electric inspection authority, or an elec-
trician, as appropriate.
