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 tog ether. This precaution may be particularly important in rural areas.

CAUTION: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority or electrician, as appropriate.

NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface.

Returns a “high-order” byte of the calculated EQM (“eye quality monitor”). This can range from 0 to 255. When the value is 8 or greater, the modem will automatically retrain if enabled by the AT%E1 command. The value for a normal connection ranges from 0 to 2 and approaches 8 for a progressively poorer connection. Returns an OK result code.

This section defines the purpose of the modem registers, and sequentially lists the registers and describes their functions. These registers affect various operating characteristics and allow you to obtain information about the modem, as well as test the modem. Each register has a factoryset value, which you can read or change to fit your needs.

This extended-format command selects the modulation and, optionally, enables or disables automode, specifies the lowest and highest connection rates, selects m-Law or A-Law codec type, and enables or disables robbed bit signaling generation (server modem) or detection (client modem) using one to five subparameters. The command format is:

+MS=<mod>[,[<automode>][,[<min_rate>][,[<max_rate>][,[<x_law>] [,[<rb_signal>][,[Maxup_rate>]]]]]]<CR>

Notes:

1. For 14400 bps and lo wer speeds, the Nn command and S37 register can alternatively be used, in which case the +MS subparameters will modified to reflect the Nn and S37=x settings. Use of the Nn and S37=x commands is not recommended but is provided for compatibility with existing communication software. (S37 is not updated by the +MS command.)

2. Subparameters not entered (enter a comma only or <CR> to skip the last

subparameter) remain at their current values.

Reporting Selected Options

The modem can send a string of information to the DTE consisting of selected options using the following command:

+MS?

The response is:

+MS: <mod>,<automode>,<min_r ate>,<max_rate>,<x_law>,<rb_signaling>

Reporting Supported Options

The modem can send a string of information to the DTE consisting of supported options using the following command:

+MS=?

The response is:

+MS: (list of supported <mod> values), (list of supported <automode> values),(list of supported <min_rate> values), (list of supported <max_rate> values), (list of supported <x_law> values), (list of supported <rb_signaling> values)

For example,

+MS: (0,1,2,3,9,10,11,56, 64,69),(0,1),(300-33600),(300-56000),(0,1),(0,1) [56000]: maximum rate

Notes:

1. See optional <automode>, <min_rate>, and <max_r ate>

subparameters.

2. For V.23, originating modes transmit at 75 bps and receive at 1200 bps; answering

modes transmit at 1200 bps and receive at 75 bps. The rate is always specified as 1200 bps.

The modem may also automatically s witch to another modulation (automode), subject to the following constraints:

a. The modem may not be able to automatically switch from the current

modulation (specified by <mod>) to some other modulation. For

example , there is no standard wa y to automode from Bell 103 to V.23. b. The DTE may disable automode operation (see <automode> belo w). c. The DTE may constrain the range of modulations available by

specifying the lowest and highest rates (see <min_r ate> and

<max_rate> below).

3. <automode> is an optional numeric value which enab les or disab les automatic modulation negotiation using V.8 bis/V.8 or V.32 bis Annex A. The options are:

<automode> Option Selected

0 Automode disabled 1 Automode enab led using V.8 bis/V.8 or V.32

Boca 112K DynamicDuo ModemBoca 112K DynamicDuo Modem

Boca 112K DynamicDuo Modem

Boca 112K DynamicDuo ModemBoca 112K DynamicDuo Modem

Annex A (Default)

4747

The default value is 1, which enables automode. Note , however, there are modulations for which there is no automatic negotiation, e.g., Bell 212 (<mod> = 69).

For <automode> = 0 (automode disabled, i.e., fixed modulation):

a. If <max_rate> is within the rates supported by the selected modulation,

the selected rate is that specified by <max_rate>. For example: +MS=10,0,1200,4800,0,0,4800 selects V.32 bis 4800 bps fixed rate.

b. If <max_rate> is greater than the highest speed supported by the

modulation specified by <mod>, the starting rate is the highest rate supported by the selected modulation. For example:

+MS=10,0,2400,50000,0,0,14400 selects V.32 bis 14400, 12000, 9600, 7200, or 4800 bps.

c. To emulate issuance of the N0S37=x command sequence to select fix ed

mode operation, specify the <max_rate> and <min_rate> both to be the (same) requested speed, and <mod> to be the modulation for that speed. For example: +MS=11,0,16800,16800,0,0,21600 selects V.34 16800 bps fixed mode (no comparable S37 command). +MS=10,0,12000,12000,0,0,14400 selects V.32 bis 12000 bps fixed mode (same as N0S37=10).

For <automode> = 1 (automode enabled, i.e. , automatically selected speed and modulation):

The modem connects at the highest possible rate in accordance with V.8 bis/V.8, or V.32 bis Annex A if V.8 bis/V.8 is not supported by the remote modem.

a. If <max_rate> is greater than the highest rate supported by the modulation

specified by <mod>, the modem automodes down from the highest rate of the selected modulation. For example: +MS=10,1,1200,24000,0,0,14400 selects automoding down from V.32 bis 14400 bps.

Modem Command ReferenceModem Command Reference

Modem Command Reference

Modem Command ReferenceModem Command Reference

4848

b . To emulate issuance of the N1S37=x sequence command, specify the

modulation and the rate to start automoding down from using <mod> and <max_rate>, respectiv ely. Set <min_rate> to 300 to allo w automoding all the wa y down to V.21 300 bps. For example: +MS=11,1,300,16800,0,0,28800 selects automode starting at V.34 16800 bps (no comparable S37 command). +MS=9,1,300,12000,0,0,12000 selects automode starting at V.32 bis 12000 bps (same as N1S37=10).

3. <min_rate> is an optional number which specifies the low est r ate at which the modem may establish a connection. The value is decimal coded, in units of bps, e.g., 2400 specifies the lowest r ate to be 2400 bps. The default is 300 for 300 bps.

4. <max_rate> is an optional number which specifies the highest rate at which the

modem may establish a connection. The v alue is decimal coded, in units of bps, e.g., 14400 specifies the highest rate to be 14400 bps. The default is 28800 for 28800 bps.

5. <x_law> (56K only) is an optional number which specifies the codec type. The

options are (µ-Law):

0 = µ-La w 1 = A-Law

6. <rb_signaling> (56K only) is an optional number which enables or disab les robbed bit signaling generation in a server modem or enables or disab les

robbed bit signaling detection in a client modem. The options are:

0 = Robbed bit signaling generation (server modem ) or detection (client modem) disabled (default)

1 = Robbed bit signaling generation (server modem ) or detection (client modem) enabled

Note that ATZ will reset the <rb_signaling> selection to 0 (disabled). Result Codes: OK V alid subpar ameter string

ERROR Otherwise.
