Primitive Code

Description

 

 

 

L

Local phone

+VLS=m

0

 

T

Telco line

(cont.)

 

M0

Internal microphone

 

 

 

 

 

M1

External microphone

 

 

 

S0

Internal speaker (requires squelch on any microphone activity)

 

 

 

S1

External speaker (requires squelch on any microphone activity)

 

 

 

H0

External microphone and speaker combination (handset or headset)

 

 

NOTE: For speakerphone applications, see ATI10, +VSP, and “Speakerphone AT Command

 

 

 

Requirements” in the Voice Application Note for more details.

 

 

 

 

 

Automatic Hang-Up Control: This command changes the way the modem responds to hang-up

 

 

commands after it switches from voice mode to fax or data modes.

 

 

Range: 0–2

 

+VNH=m

0

0*

The modem retains automatic hang-ups as normal in data and fax modes

 

 

1

The modem disables automatic hang-ups usually found in non-voice modes

 

 

2

The modem disables all automatic hang-ups usually found in non-voice modes except a

 

 

 

‘logical’ hang-up

 

 

 

 

 

 

Ringback-Goes-Away Timer: After originating a call in voice mode, this command selects the length

 

 

of time the DCE waits between ringbacks before the DCE assumes the remote party has gone off

 

 

hook. After dialing a phone number and detecting a ringback, the modem sends <DLE><O> to the DTE

 

 

if another ringback is not detected within this timer value. This indicates that the remote telephone has

+VRA=m

50

been picked up (that is, gone off-hook). The ringback-goes-away timer is reset every time a new

ringback is detected.

 

 

 

 

 

 

Range: 0–50 (in 100 ms increments)

 

 

0

The DCE returns the ‘OK’ code immediately after ringback.

 

 

50*

(50 = 5.0 seconds)*

 

 

 

 

 

Ringback-Never-Appeared Timer: This command sets the length of time the DCE waits for ringback

 

 

when originating a call in voice mode. After dialing a phone number, the modem sends an ‘Error’ result

 

 

code to the DTE if ringback is not detected before the timer value elapses. This may indicate one of

 

 

several conditions: the remote telephone was picked up before the ringback tone was generated; the

+VRN=m

10

number is no longer in service; or the number was incomplete. This timer is disabled after detecting the

first ringback.

 

 

 

 

 

 

Range: 0–255 (in 1 second increments)

 

 

0

The DCE immediately returns the OK result code after dialing

 

 

10*

(10 = 10 seconds)*

NOTE: An asterisk (*) denotes the factory-default setting.
