Step
16. Configure the polling interval.
17. Set the line idle-code.
18. (Optional.) Enable RTS signal
reverse.
19. (Optional.) Set the intended
bandwidth for the
synchronous serial interface.
20. (Optional.) Restore the default
settings for the synchronous
serial interface.
21. Bring up the synchronous
serial interface.

Configuring an AM interface

The analog modem (AM) interface combines the functionality of the asynchronous serial interface and
analog modem. The AM interface supports most of the commands available on asynchronous serial
interfaces and modems. When you configure an AM interface, you can treat it as a special asynchronous
serial interface.
AM interfaces provide dial-in and dial-out services for analog dial-up users. The actual connect rates
depend on the network conditions, including the line quality and connection protocol.
The following are the maximum downstream and upstream rates that the AM interface can provide:
If the peer (typically an ISP) uses a digital modem, the AM interface can use the V.90 Modem
•
standard to set up connections. The maximum downstream rate is 56 kbps and the maximum
upstream rate is 33.6 kbps.
• If the peer (typically a subscriber) uses an analog modem (or an AM interface), the AM interface
can use the V.34 Modem standard to set up connections. The maximum downstream and upstream
rates are both 33.6 kbps.

Remarks
The default is 10 seconds.
The default is 0x7E.
By default, RTS signal reverse is
disabled.
By default, the expected
bandwidth (in kbps) is the interface
baud rate divided by 1000.
N/A
By default, a synchronous serial
interface is up.
