Dn (cont'd)

W or + ± Wait for dial tone. Modem waits for a second dial tone before

 

 

 

processing the dial string. This can be the initial dial tone or a second

 

 

 

tone received when dialing through a tandem PBX (for example,

 

 

 

9+555-6789), or when invoking special features (for example,

 

 

 

70#W555-6789, where 70# disables Call Waiting).

 

 

R ±

Reverse Dial mode. Causes the originating modem to send out an

 

 

 

answertone once it no longer detects ringback. (Ringback is the ring you

 

 

 

hear at the originating site when making a call.) The R parameter must be

 

 

 

the last character in the dial string. For correct operation, at least one

 

 

 

ringback must be detected; therefore, the remote modem should be

 

 

 

configured to answer on the second ring or subsequent rings.

 

 

 

 

 

@± Quiet answer. Wait for five seconds of silence after dialing the number. If the silence is not detected, the modem sends either a NO ANSWER result to the DTE.

!± Hook flash. This causes the modem to go on-hook for 0.5 seconds then return to off-hook.

 

; ± Return to Command mode. Modem returns to Command mode after

 

 

dialing a number without disconnecting the call. This is useful when the

 

 

number exceeds 40 characters, or when the wait time between parts of a

 

 

dial string is unknown.

 

 

Space, ± , and ( ) . These characters are ignored by the dial string and can be

 

 

included in the dial string to enhance readability.
