HIGH SPEED Modem and FAX FAMILY

Cermetek Microelectronics 

Cermetek Microelectronics, Inc.

CANADIAN APPROVALS

The HS Modem family is approvable for use by DOT to

CSA CS-03 Part I. However, per Canadian

procedures, approval can only be granted after the HS

Modem has been installed into the end product.

Typically, Canadian approval is obtained by submitting

the final end product to an independent test house or

consultant for evaluation. The test house/consultant

then forwards the test results and applicable

documents to the regulatory agency. Cermetek offers

a list of consultants to assist with this process.

High Speed Modem and FAX Family

In addition to restriction notification, the FCC requires

that Cermetek make all repairs to all products in the

HS Modem family. If repairs are necessary after

installation of the HS Modem and the end product has

been delivered to the end user, the end product must

be returned to the end product supplier where the HS

Modem can be removed and then forwarded to

Cermetek for repair. The following notice is

recommended and should be included in the end

product’s user manual.

PAN-EUROPEAN TBR21 APPROVALS

The CH1799TBR/ETBR and CH2056TBR/ETBR

products have been designed to meet the

requirements of ETSI TBR – 021 Pan-European

Approval for Connection to Analogue Public Switched

Telephone Networks in addition to the FCC Part 68

conveyed approval, Canadian DOT CSA CS-03 Part I

compliance and UL 1950 Edition 3/CSA C22.2 950

recognition. Test reports (as required for CE marking)

demonstrating TBR21 compliance are available upon

request.

FOR YOUR USER’S MANUAL

The Part 68 rules require the following (or equivalent)

be provided to the end user of the equipment

containing a DAA:

Type of Service. The (insert end product name) is

designed to be used on standard device telephone

lines. It connects to the telephone line by means of a

standard jack called the USOC RJ-11C (or USOC

RJ45S). Connection to telephone-company-provided

coin service (central office implemented systems) is

prohibited. Connection to party lines service is subject

to state tariffs.

HS MODEM HANDLING AND ASSEMBLY

RECOMMENDATIONS

The HS Modem contains static-sensitive components

and should only be handled by personnel and in areas

that are properly protected against static discharge.

There are two mounting techniques that are

recommended for physically connecting the HS

Modem to a PCB:

1. Direct soldering.

2. Sockets.

Changes in Attestation Procedure for Plugs and

Jacks. (Name of applicant) attests that the network

interface plugs or jacks used on this equipment comply

with and will continue to comply with the mechanical

requirements specified in Part 68, Sub-part F,

specifically the dimensions, tolerances and metallic

plating requirements. The compliance of these

connectors will be assured by purchase specifications

and incoming inspection. Documentation of such

specifications and/or inspections will be provided by

the FCC within 30 days of their request for the same.

Direct Soldering. The HS Modem may be wave

soldered onto a circuit card. All HS Modem products

are hermetically sealed and will not be harmed by

industry standard wave soldering processes.

Socketing. The socketing approach to mounting

eliminates cleaning and desoldering concerns. When

the socket is used, it must make a solid connection to

all pins. Failure to do so will cause unreliable or

intermittent operation. Also, steps should be taken to

assure that the module remains tightly seated in the

socket after the end product is shipped. Cermetek

recommends socket CES-150-01-T-S by Samtec, 50

pin strip socket.

FCC REGISTRATION

All products in the HS Modem family are registered

with the FCC (except the CH1799LL) under Part 68.

To maintain the validity of the registration, you must

serve notice to the end user of the product of several

restrictions the FCC places on the modem and its use.

Telephone Company Procedure. The goal of the

telephone company is to provide you with the best

service it can. In order to do this, it may occasionally

be necessary for them to make changes in their

equipment, operations or procedures. If these

changes might effect your service or the operation of

your equipment, the telephone company will give you

notice, in writing, to allow you to make any changes

necessary to maintain uninterrupted service.

In certain circumstances, it may be necessary for the

telephone company to request information from you

concerning the equipment which you have connected

to your telephone line. Upon request of the telephone

company, provide the FCC registration number and

the ringer equivalence number (REN); both of these

items are listed on the equipment label. The sum of all

of the REN’s on your telephone lines should be less

than five in order to assure proper service from the

telephone company. In some cases a sum of five may

not be useable on a given line. Consult your

telephone provider.
