INTRODUCTION

The CH2100 is a full function, fully approved V.22bis 2400bps

modem module. It is hermetically encapsulated and has a

footprint that is less than one square inch. This makes the

CH2100 unique in size, performance and reliability . The CH2100

interfaces directly to the telephone line utilizing its built in PSTN

line interface. The modem is completely intelligent and is

controlled by and will communicate via the five volt serial transmit

and receive data pins exclusively. The CH2100 uses the

standard AT commands and status words for command and

control. No additional external pin connections are required.

Even though all other vestigial modem signals have been

eliminated, the CH2100 can communicate with any other

commercially available modem up to and including 56Kbps

modems. The CH2100 supports asynchronous operation at

2400bps, 1200bps, and 300bps to CCITT and Bell standards.

Through-hole or surface mount pins are available. The user

may select from standard temperature range or extended

temperature range versions. The CH2100 is FCC part 68

approved (which is conveyed to the user), is UL1950 and CSA

C22.2 950 compliant and is approvable in Canada to CSA CS-

03 Part I.

DESCRIPTION OF FUNCTIONAL BLOCKS AND

DISCUSSION OF BASIC OPERATIONS

Figure 1 contains a functional block drawing of the CH2100. The

CH2100 is a highly integrated, full-function modem, comprised of

a modulator/demodulator , controller , and an FCC Part 68 approved

PSTN line interface DAA (Data Access Arrangement).

Modulation/Demodulation and Modem Controller.

These functions are provided by a monolithic modem integrated

circuit. This IC has built-in facilities to accommodate integrated AT

command control and contains the necessary resident interfaces

for general communication and routing to the DAA.

Telephone Interface or DAA.

The CH2100 is designed to meet North American telephone

standards as set by FCC Part 68 (USA) and CSA CS-03 Part I

(CANADA). Among the more critical parameters, the telephone

line interface is designed to meet 1500VAC RMS and 2122 volts

peak surge isolation. Consequently, the CH2100 satisfies U.S.

and Canadian requirements, and will meet other international approval

agency requirements that specify this level of isolation.

• Low power operation with automatic reduced power

standby mode

• Automatic adaptive and fixed compromise equalization

• Test modes and diagnostics

• Size: 0.86”x1.10”x0.53” (nominal)

• Fully encapsulated

• UL1950 and CS22.2 950 compliant approval pending

• Extended Temperature: -40oC to 85oC

CH2100 comes with FCC Part 68 approval and is shipped from the

factory with an FCC Part 68 label indicating the registration number

and ringer equivalent. This label should be prominently displayed

on the end product.

GENERAL DESCRIPTION

The CH2100 has very few external pins (when compared to

conventional modems) making the CH2100 extremely easy to

interface to the user’s application hardware. Unique to the

CH2100 archeitecture is the assumption that an intelligent host

is processing the transmit and receive data, providing the AT

commands for control and interpretting the status information

supplied by the CH2100. Pins such as DCD, DSR, RST, CTS,

HS - which are commonly found on conventional modems - are

functionally duplicated with the AT command structure and have

been eliminated. This minimizes the external hardware interface

to the CH2100 while simultaneously consolidating control of the

modem into one place: the user or host controller. All

communication to the CH2100 is conveyed on the TXD (or

transmit) pin with respect to ground. All communication from the

CH2100 is received by the host controller on the RXD (or receive)

pin with respect to ground. For those users that require access

to the traditional pin set or who do not have an intelligent host

controller available for the CH2100, Cermetek recommends use

of one of our many conventional modems which offer a broad

range of externally controlled functions that collectively provide

solutions for virtually every modem application. Please access

the Cermetek web site at www.cermetek.com for other data

sheets.

er Supplyer Supply

er Supply ..

The CH2100 modem module is a complex set of sub-systems.

During the course of normal operation the CH2100 decodes ana-

log signals from the telephone line that are in the millivolt range.

Steps must be taken by the user to guarantee that power supply

noise on all supply lines, including ground, does not exceed 50

mV peak to peak. Any frequency between 20 kHz and 150 kHz

must be less than 500 micro volts peak. If necessary, use dedi-

cated power and ground planes. Failure to provide such operating

conditions could cause the CH2100 to malfunction or to function

erratically.

The CH2100 requires a single +5V ±5% supply . It is recommended

that by-pass capacitors be placed on the power supply as close to

the modem’s supply input as practical. It is recommended that a

10 µF or greater Tantalum capacitor in parallel with a 0.01µF ce-

ramic capacitor be used.

Sleep Mode.

To minimize power consumption, the CH2100 includes a power

down feature called Sleep Mode. When activated, the CH2100 will

automatically enter Sleep Mode after 0 to 254 seconds of inactivity.

The inactivity delay is selected using the ATS24 command. The

CH2100 is delivered from the factory with a 5 second inactivity

delay enabled (i.e., ATS24=5). The CH2100 returns to normal

operation when a ring signal is received or upon an input low

signal on the TXD pin. A TS24 = 255 disables the Sleep Mode and

is the default if no value is set in register S24. In Sleep Mode,

power is reduced to approximately 50% of normal operating power .

T ransmission Speed.

In normal operation, the originating modem initiates the call and

attempts to connect to the answering modem at a speed estab-

lished by the originating modem’s controller prior to call initiation.

This is referred to as the Initial Trained Rate. Upon receiving the

call, the answering modem will attempt to connect to the originat-

ing modem at its Initial Trained Rate.

If these two rates are identical, the connection is made. If the

speeds differ, the answering modem must adjust its rate or termi-

nate the call. Table 1 indicates the connection rate that will result

when the calling modem’s Inital Trained Rate and the answering

modem’s Initial Trained Rate are different.

Note that a 2400 baud connection rate will only result if both mo-

dems are initially set at 2400 baud.

SUPPORTED FEATURES

“AT” Command Set.

A 40-character command line is supported. The command line

starts with AT and may contain standard or enhanced commands.

A summary is available in this data sheet while a detailed descrip-

tion is available from our web site.

Serial Host Interface.

The serial interface signals conform to V.24 (EIA-232).

See pin description.

The RI pin toggles low when the CH2100 detects an incoming call.

The RI pin is TTL compliant and can be utilized to activate external

circuitry including the external RST pin.

Speed and Parity Selection.Speed and Parity Selection.

Speed and Parity Selection.

Prior to call initiation, the host controller trains the modem to the

host speed (2400, 1200, or 300 bps) and parity (odd, even, mark,

space, or none) via a host-initiated training sequence. This train-

ing also sets the speed of the data for originate calls. The CH2100

will automatically adjust to the originators speed when answering

calls.

The CH2100 matches the host’s parity when it returns status mes-

sages to the host. During a data connection, however, the modem

passes parity through without interpretation or alteration.

With the exception of the U.S., most countries (including Canada)

require submission of the final product or system containing the

CH2100 to the appropriate governing regulatory agency for

approval. Typically this is accomplished by submitting the final

end product to an independant test house or consultant for

evaluation. The test house/consultant then forwards the test

results and applicable documents to the regulatory agency. Call

Cermetek for a list of consultants.

MODEM CONTROLMODEM CONTROL

MODEM CONTROL

The CH2100 modem may be controlled by sending serial ASCII

command sequences. The commands are sent to the modem

serially on the TXD pin. After execution of a received command, the

modem returns a serial status message that can be read on pin

RXD. This message indicates command completion status. Re-

fer to Table 3 for a complete list of result codes.

The user can also reset the modem externally by applying a low-

going reset pulse to the RST pin for at least 10ms after the +5V

power supply has stabilized. This can be accomplished in one of

two methods. In the Reset on Power Up method, a resistor/ca-

pacitor network is used. Refering to figure 2, the reset pulse, with

the appropriate delays, are generated automatically when 5V are

applied simultaneously to the CH2100 and to the Reset on Power

Up circuit. Delay sending commands to CH2100 for 200ms after

reset has been initiated to allow the CH2100 to properly reconfigure.

TTL Controller Reset.

To reset the modem externally using the second reset method,

TTL Controller Reset, the modem must be powered up and the

5V supply must have stabalized prior to utilizing this method.

Refering to the TTL Controller Reset circuit in figure 2, a 10msec

low-going pulse is sent from the controller through the inverter.

Delay sending commands to CH2100 for 200ms after reset has

been initiated to allow the CH2100 to properly reconfigure.

Training the Modem.

Each modem must be trained to match its host’s speed and parity

so that it is able to recognize serial asynchronous commands

sent to it by the host UART. The host must retrain the modem each

time a reset signal is applied on RST or after a RESET serial

command has been issued.

Modem Training Command Sequence.

The CH2100 is trained by sending it the following sequence:

Enter: AT[CR]

Where: A and T may be either upper or lower case but must be the

same case.

[CR] repesents carriage return

The “AT” sequence is referred to as an attention sequence. The

CH2100 will respond with one of the following status messages,

depending on whether it is optioned for abbreviated or English

status messages.

A T [commands] [CR].

Where: [AT] represents attention sequence.

[commands] represents command strings.

[CR] represents carriage return (ASCII 13 or HEX 0D).

When entering commands to the modem, the backspace charac-

ter-control-H (ASCII 8 or HEX 08) can be used to edit mistakes.

Enter: ATE0A[CR]

Result: 0[CR] (Abbreviated form)

Result: [CR][LF]OK[CR][LF] (English form)

Where: [CR] represents carriage return (ASCII 13 or HEX 0D).

[LF] represents line feed (ASCII 10 or HEX 0A).

An alternate attention sequence “A/” may be sent which behaves

much like the AT sequence except that it causes the previously

entered command specified with an AT prefix to be executed.

When given, it must be in upper case ASCII. No carriage return is

needed.

THE COMMAND FORMAT

Typical commands consist of three elements: the attention se-

quence, the commands themselves, and a terminating carriage

return.

The basic status code subsets are enabled with the Xn command.

Where n=0,1,2,3,4 establishes the result codes allowed by the

user.

X0 - Result Codes 0, 1, 2, 3, 4 allowed

X1 - Result Codes 0, 1, 2, 3, 4, 5, 10 allowed

X2 - Result Codes 0, 1, 2, 3, 4, 5, 6, 10 allowed

X3 - Result Codes 0, 1, 2, 3, 4, 5, 7, 10 allowed

X4 - Result Codes 0, 1, 2, 3, 4, 5, 6, 7, 10 allowed

The CH2100 is factory set to X4, which allows all result codes.

AT Command Set.

The available command set is divided into four types of com-

mands: dial modifiers, basic commands, ampersand and per-

cent commands. Refer to the complete list in Table 5.

AT Command Data Rate.

With the serial interface, the rate is speed sensed for parity and

format.

THE STATUS MESSAGES

The CH2100 responds with a status message after each com-

mand is executed. This status message may either be a single

digit followed by a carriage return or a carriage return and line feed

with a message in English, followed by a carriage return and line

feed.

“AT” and “A/” may not be edited however. Multiple commands may

be placed in the command line. A command line may be as long

as 40 characters, excluding the letters AT. By way of example, the

command below instructs the CH2100 to configure itself to not

echo characters when in command mode (E0) and then put itself

in answer mode (A).

MODEM STATES

The CH2100 can be in either command mode or data mode.

When the modem is idle, it is in command mode by default. When

data transmission is in progress, the CH2100 is in the data mode

state and will not recognize commands. To force the CH2100 to

recognize commands, the host must send an “escape sequence”

to the CH2100 forcing it out of data mode and into command

mode.

The escape sequence consists of a “guard time” (a period where

no characters are sent to the modem), followed by 3 escape

characters, followed by another guard time. At powerup, the guard

time is set to 1 second minimum, and the escape character is set

as “+.” These two parameters can be modified via registers S12

and S2, respectively.

The CH2100 will stay off-hook with its carrier on after the escape

sequence is received and it returns an OK status message when

it is ready to accept commands. The CH2100 can be put into data

mode by issuing the command ATO [CR].

AT COMMAND APPLICATIONS

Dialing A Phone Number.

The Dial command takes the form Dn, where n is a string of char-

acters. In the simplest form, n will be only the digits of the phone

number to be dialed.

Example: Dial number.

Enter: A T D1234567

In response to this command, the CH2100 dials the telephone

number “123-4567” and then waits for a carrier from the distant

modem. If no carrier is detected within a given time (the default

time is 30 seconds), the CH2100 automatically releases the line

and sends a NO CARRIER result code. If a carrier is detected, the

CH2100 gives a CONNECT result code and goes on-line, permit-

ting communication with the distant modem.

The Dial Command may also be issued without a telephone num-

ber. ATD causes the modem to pick up the telephone line without

dialing a number.

Pause During Dialing.

When placing a call from an office with a telephone connected to a

PBX, it may be necessary to dial an access code (usually the digit

9) to get an outside line. Inserting a comma in the telephone

number instructs the modem to pause for a specific length of time.

The factory set default pause time is 2 seconds.

Example: Dial 9, pause, dial number.

Enter: AT DT9, 1234567

Multiple commas may be used to generate integer multiples of the

specified delay time.

Originate a Call in Answer Mode.

The D command forces the modem into originate mode. To call

an originate-only modem, dial the number and set the modem to

answer mode via the R command (reverse originate). This is

done by including an R at the end of the telephone number.

Example: Change modem from original-only to answer mode.

Enter: A T DT 1234567R

Redial Last Number.

Use A/, the repeat command, to redial the last telephone number

dialed.

Return to Command State.

The modem can be forced to reenter the command state after

dialing (without hanging up) by ending the dial command with a

semicolon. This is useful when using the modem as an auto

dialer.

Example: Touch-tone dial 9, pause, dial number, return for

command.

Enter: A T DT9, 1234567;

Result: OK

Automatic Answering.

The S0 register controls the number of rings that must occur

before the modem answers a call. The register may range in

value from 0 to 255.

S0 = 0 DO NOT ANSWER TELEPHONE

S0 = 1 ANSWER ON RING 1

S0 = 2 ANSWER ON RING 2

S0 = 3 ANSWER ON RING 3

S0 = 255 ANSWER ON RING 255

When S0 is set to 0, the modem will not auto-answer.

CONNECTING TO THE HOST UART

Since the CH2100 communicates data serially and most host

products handle data in a parallel format, a UART is needed to

make parallel-to-serial and serial-to-parallel translations.

The modem is controlled by sending it serial commands over TXD

and can be monitored by serial status messages returned on

RXD. RI is optionally used to monitor the ring signal.

PHONE LINE CONNECTION GUIDELINES

1) The CH2100 must be mounted in the final assembly such

that it is isolated from exposure to any hazardous voltages

within the assembly. Adequate separation and restraint of

cables and cords must be provided.

2 ) The circuitry from the CH2100 to the telephone line interface

must be provided in wiring that carries no other circuitry other

than that specifically allowed in the FCC rules (such as A and

A1 leads).

3) Connection to phone line should be made through an RJ-11

jack.

4) PCB traces from the modem’s RING and TIP pins to the RJ-11

jack must be 0.1 inch spacing or greater to one another and

0.2 inch spacing or greater to all other traces. The traces

should have a nominal width of 0.020 inches or greater.

5 ) The RING and TIP PCB traces should be as short as possible

and oriented to prevent coupling other high speed or high

frequency signals present on the host circuit PCB.

6) No additional circuitry other than that shown in Figure 3 may

be connected between the modem module and the RJ-11

jack. Doing so will invalidate the FCC approval.

7) The CH2100, the RJ-11 jack, the interfacing circuitry and all

PCB traces in between, must be contained on a PCB with a 94

V-0 flammability rating.

8) The supplied FCC registration label must be applied visibly

on the outside of the product.

9) The product’s User Manual must provide the user with instruc-

tions for connection and use as recommended in the FCC

Registration Section below.

Table 5. CH2100 “AT” Command Set Summary

CH2100 HANDLING AND ASSEMBLY

RECOMMENDATIONS

The CH2100 contains static-sensitive components and should

only be handled by personnel and in areas that are properly pro-

tected against static discharge.

There are two mounting techniques that are recommended for

physically connecting the CH2100 to a PCB: 1) sockets, and 2)

direct soldering.

Direct Soldering.

The CH2100 may be wave or vapor phase soldered onto circuit

boards. All CH2100 products are hermetically sealed and will not

be harmed by industry standard 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

operation. Also, steps should be taken to assure that the module

remains tightly seated in the socket after the end product is shipped.

Recommended socket is CES-150-01-T-S by Samtec, 50 pin strip

socket. Socketing SMD versions of the CH2100 is not recom-

mended.

FCC REGISTRATION

All products in the CH2100 family are registered with the FCC

(Federal Communications Commission) under Part 68. To main-

tain 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.

In addition to restriction notification, the FCC requires that

Cermetek make all repairs to all products in the CH2100 family. If

repairs are necessary after installation of the CH2100 in the end

product and the end product has been delivered to the end user,

the end product must be returned to the end product supplier where

the CH2100 can be removed and then forwarded to Cermetek for

repair. The following notice is recommended and should be in-

cluded in the end product’s user manual.

FOR YOUR USER’S MANUAL

The Part 68 rules require the following (or equivalent) be provided

to the end user of 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 tele-

phone 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.

Changes in Attestation Procedure for Plugs and Jacks:

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

Cermetek Microelectronics, Inc. Document No. 607-2100 Rev.C (8/99) 71999

In certain circumstances, it may be necessary for the telephone

company to request information from you concerning the equip-

ment 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 aII 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.

If Problems Arise: If any of your telephone equipment is not oper-

ating properly, you should immediately remove it from your tele-

phone line, as it may cause harm to the telephone network. If the

telephone company notes a problem, they may temporarily dis-

continue service. When practical, they will notify you in advance of

this disconnection. If advance notice is not feasible, you will be

notified as soon as possible. When you are notified, you will be

given the opportunity to correct the problem and informed of your

right to file a complaint with the FCC. Contact your local telephone

service provider if you have any questions about your phone line.

In the event repairs are ever needed on the (insert your product

name), they should be performed by (insert your company name)

or an authorized representative of (insert your company name).
