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.

content or billing information which is intended to be decoded within the tele-
communications network.
( ) The encoded analog content and billing protection is factory set and is not
under the control of the customer.
I attest that the operator(s) maintainer(s) of the digital CPE responsible for the
establishment, maintenance and adjustment of the encoded analog content and
billing information has (have) been trained to perform these functions by suc-
cessfully having completed one of the following (check appropriate blocks):

FCC regulations require that the following information be provided in this
manual:
1. This equipment complies with Part 68 of the FCC rules. On the bottom of
the equipment housing is a label that shows the FCC registration number
and Ringer Equivalence Number (REN) for this equipment, if applicable. If
required, this information must be given to the telephone company.
2. The following information may be required when applying to the local tele-
phone company for leased line facilities.
3. The following information may be required when applying to the local tele-
phone company for a dial-up line for the V.34 or V.32.
4. The REN is useful to determine the quantity of devices you may connect to
your telephone line and still have all of those devices ring when your num-
ber is called. In most, but not all areas, the sum of RENs of all devices
should not exceed 5. To be certain of the number of devices you may con-
nect to your line, as determined by REN, you should call your telephone
company to determine the maximum REN for your calling area.
5. An FCC compliant telephone cord with a modular plug may be provided
with this equipment. This equipment is designed to be connected to the tele-
phone network or premises wiring using a compatible modular jack, which
is FCC Part 68 compliant. See installation instructions for details.
6. If this equipment causes harm to the telephone network, the telephone com-
pany may temporarily discontinue service. If possible, advance notification

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 equip-
ment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio fre-
quencies. 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 inter-
ference 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 emis-
sions from digital apparatus as set out in the interference-causing equipment
standard entitled “Digital Apparatus," ICES-003 of the Department of Commu-
nications.
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.

Canadian Equipment Limitations
Notice: The Canadian Industry and Science Canada label identifies certified
equipment. This certification means that the equipment meets certain telecommu-
nications network protective, operational, and safety requirements. The Depart-
ment 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
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 elec-
trician, as appropriate.
