Multi-Tech Systems MA820 사용자 설명서

5.  If the modem usage is Modem Sharing and the calls are in-bound, click the 

on option for the Caller ID. 

6. Click 

Update for Modem Configuration: POTS modem x. 

7.  Repeat the above procedure for POTS modem 2 on the MA220, POTS 

modems 2 thru 4 on the MA420 or POTS modems 2 through 8 for the 
MA820. 

The Authentication menu displays two ports for the MA220, four ports for the 
model MA420 or eight ports for the model MA820. The Authentication/Radius 
Client Configuration:POTS modem X fields allow you to select and define 
certain user authentication details on a per port basis.   

The Authentication Type option, on this menu, applies only to RAS, PPP, calls. 

Please Note: When Modem Sharing, in Modem Setup, is configured to 
implement Radius Authentication it will use the RADIUS Client details defined 
here to authenticate the user, regardless of how the Authentication Type option 
on this menu is set. 

 

When the authentication method is local, use the Local User menu to build a 
Database of user credentials. The MultiAccess matches the credentials 
provided by the caller with the credentials listed in the Local User Database. 
Additionally, local users can be configured for PPP call back. 

When the Authentication Type is Radius, the MultiAccess sends the credentials 
provided by the caller to the Radius Server for authorization. 
For RAS calls, dial-in PPP, a second static IP address is needed in the Remote 
Host Address field. This address is for the dial-in user, PPP peer. This address 
needs to be on the same subnet, network number, as that of the MultiAccess.
