Affidavit Requirements for Connection to Digital Services
• An affidavit is required to be given to the telephone company whenever digi-
tal terminal equipment without encoded analog content and billing protec-
tion 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
information is being transmitted or that the output of the device meets Part 68
encoded analog content or billing protection specification.
• End use/customer will be responsible to file an affidavit with the local
exchange carrier when connecting unprotected CPE to a 1.544 Mbps or sub-
rate digital service.
• Until such time as subrate digital terminal equipment is registered for voice
applications, 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
digital 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 frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio frequencies.
Operation of this equipment in a residential area is likely to cause harmful inter-
ference 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
entitled “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 Com-
munications.
Change or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.

ix
Canadian Equipment Limitations
Notice: The Canadian Industry and Science Canada label identifies certified
equipment. This certification means that the equipment meets certain telecom-
munications network protective, operational, and safety requirements. The
Department does not guarantee the equipment will operate to the user’s satisfac-
tion.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equip-
ment must also be installed using an acceptable methods of connection. In some
cases, the company’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 degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian main-
tenance facility designated by the supplier. Any repairs or alterations made by the
user to this equipment, or equipment malfunctions, may give the telecommunica-
tions company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connec-
tions 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 prevent overloading. The termination on a loop may consist of any combina-
tion 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
electrician, as appropriate.
