*LN

Link Telephone Numbers

 

 

Lets you link telephone numbers stored in the modem’s

 

 

Phonebook. You can provide more than one number to

 

 

call in case one is busy. If a call fails and the number is

 

 

linked, the modem pauses and then calls the linked

 

 

number. NOTE: With this feature enabled, the modem

 

 

dials linked numbers before redialing the first number.

 

 

To link numbers, enter AT*LN, followed by the entry n

 

 

of the number you want to link from, a comma, and the

 

 

entry m of the number to link. Example: AT*LN2,4.

 

 

Here, 2 is linked to 4. To clear this link, enter AT*LN2.
