Affidavit for Connection of Customer Premises Equipment to 1.544
MBPS and/or Subrate Digital Services
For the work to be performed in the certified territory of ______________ (telco name)
State of ________________________________
County of ______________________________
I, _______________________ (name), ____________________ (business address),
_____________________ (telephone number) being duly sworn, state:
I have the responsibility for the operation and maintenance of the terminal equipment
to be connected to 1.544 Mbps and/or __________________ subrate digital services.
The terminal equipment to be connected complies with Part 68 of the FCC rules
except for the encoded analog content and billing protection specification.
With respect to encoded analogcontent and billing protection:
( ) I attest that all operations associated with the establishment, maintenance and
adjustment of the digital CPE with respect to encoded analog content and billing pro-
tection information continuously complies with Part 68 of the FCC rules and Regula-
tions.
( ) The digital CPE does not transmit digital signals containing encoded analog con-
tent or billing information which is intended to be decoded within the telecommuni-
cations 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 CPEresponsible for the estab-
lishment, maintenance and adjustment of the encoded analog content and billing
information has (have) been trained toperform these functions by successfully having
completed one of the following (check appropriate blocks):
( ) A. A training course provided by the manufacturer/grantee of the equipment used
to encode analog signals; or
( ) B. A training course provided by the customer or authorized representative, using

vi
training materials and instructions provided by the manufacturer/grantee of the
equipment used to encode analog signals; or
( ) C. An independent training course (e.g., trade school or technical institution) rec-
ognized by the manufacturer/grantee of the equipment used to encode analog sig-
nals; or
( ) D. In lieu of the proceeding training requirements, the operator(s)/maintainer(S) is
(are) under the control of a supervisor trained in accordance with _______________
(circle one) above.
I agree to provide ____________________ (telco’s name) with proper documentation
to demonstrate compliance with the information in the preceding paragraph, if so
requested.

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 use/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 par-
ty 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 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 electrician, as
appropriate.
