Nortel Networks 311 S registers

Hayes dialing 467

Command Description

ATEn Echo (n = 0, 1; if n = 1, commands echo back to terminal)

ATTSP! Transparent mode

Note 1: To use AT dialing, enter CTRL-z at carriage return (<CR>) when the port is idle.

Note 2: Follow each command (except A/) by a carriage return (<CR>) to execute it.

For the purposes of this document, when illustrating the prompt/response

sequences, the bold type is what the user enters on the keyboard. All

other type represents the DAC output. Likewise, "xxxxxxx," "yyyyyyy,"

or "zzzzzzz" represents numbers entered by the user, or dialed by the

DAC,and in no way indicates the absolute character limit. The number of

characters is dependent on the feature activated(Auto Dial, Speed Call, for

example). Also, for simplicity purposes, all Result messages are shown in

Verbosecode. See Table 181 "Hayes dialingresult codes and messages"

(page 465) for a complete list of the Verbose and Numeric codes. See

Features and Services (NN43001-106-B) for a complete description of the

features operating.

S registers

These commands allow the user to access various dialing parameters. The

user can determine the present parameter setting, and alter the parameter.

These parameters are grouped into a set referred to as the S registers.

All S registers may be changed with the exception of S1, the Ring count.

If an attempt is made to change thisparameter, the command is accepted

but no action is taken. The Ring count is the number of expired 6-second

intervals since an inbound call has been received. The current count may

be displayed through the DisplayS register command but cannot be altered

After a call is dropped, the Ring counter is set back to 0.

If, when using the display or alter commands, no register or value number is

input, the number 0 is used. For example, ATS?is equivalent to ATS0.

Allowable S registers Table183 "Allowable S registers" (page 468) shows

the supported S registers allowed by the DAC.This table shows the register

number, the range accepted (decimal values shown), and a description of

the register. Whenever a register value is changed, the DAC checks for

validity. If the value entered is not within the allowed range, all processing

ceases and no command processing following the invalidentr y is accepted.

The DAC sends an ERROR result message.
