Asynchronous Call Control (ACC)
You can configure the ACC module to answer calls made to a modem
connected to an asynchronous port, to validate the user making the call and to
configure the port to the mode appropriate for the desired service. Also, you
can configure ACC to originate calls by controlling a modem attached to an
asynchronous port and to switch the port to the appropriate mode once a
connection to the remote device is established.
To assign a user an IP address and MTU (Maximum Transmission Unit) for use
with an ACC call, enter the command:
SET USER=login-name IP=ipadd MTU=mtu
To assign an IP address and MTU to the asynchronous port accessed by the
ACC call, enter the command:
SET ASYN=asyn-number IP=ipadd MTU=mtu
For more information about ACC, see the Asynchronous Call Control (ACC)
chapter in the Software Reference.
ADSL and ATM (models with ADSL port)
The AR440S router supports ADSL Annex A for connection to a POTS line. The
AR441S router supports ADSL Annex B for connection to an ISDN line.
The routers support ATM permanent virtual channels (PVCs), AAL5, and a
number of higher layer protocols that can be configured over ATM and ADSL
on the router as shown in Figure 12 on page 72.

■ PPPoA
■ IPoA
■ RFC 1483 Routed
■ RFC 1483 Bridged
For more information about ADSL and ATM, see the ATM over ADSL chapter
in the Software Reference. The chapter includes step-by-step configuration
instructions and examples for PPPoE over ATM, PPPoA and RFC 1483 Routed
(used in the sense of a connection where the subscriber premises device routes
packets onto the ADSL link, for a detailed definition see the ATM over ADSL
chapter).
