This equipment complies with Part 68 of the FCC rules. On the equipment is a label or silk screened text that
contains, among other information, the FCC registration number for this equipment. If requested, please provide this
information to your telephone company.
If your T1 equipment causes harm to the telephone network, the telephone company may discontinue your service
temporarily. If possible, they will notify you in advance. But if advance notice is not practical, you will be notified as
soon as possible. You will be advised of your right to file a complaint with the FCC.
Your telephone company may make changes in facilities, equipment, operations, or procedures that could affect the
proper operation of your equipment. If so, you will be given advance notice so as to give you an opportunity to
maintain uninterrupted service.
No repairs may be performed by the user. Should you experience difficulty with this equipment, refer to the Warranty,
Sales and Service Information section on page A.
Make the T1 network connection using a Universal Service Order Code (USOC) type RJ48C jack for single-line
installations and type RJ48H jack for multiline installations. Specify both the Service Order Code 6.0N, as well as the
proper Facility Interface Code, to the telephone company when ordering the T1 line. The T1 equipment can be
configured to support any of the framing format and line signaling techniques shown in the table below. The T1
equipment’s configuration must correspond to the T1 line’s parameters.

The Federal Communication’s Commission (FCC) requires that the end user (person responsible for operation and
maintenance of the equipment) file an affidavit with the local exchange carrier when connecting unprotected
Customer Premises Equipment (CPE) to the public T1 network. The T1 equipment is considered an unprotected CPE
because the analog through transmission gain paths, associated with the voice cards, are user adjustable. This
affidavit is required whenever digital terminal equipment without encoded analog content and billing protection is used
to transmit digital signals containing encoded analog content which is intended for eventual conversion into
voice-band analog signals and retransmitted on the network. This 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 specifications. An affidavit form has been provided for your convenience.
