Connecting to a V.34 Modem Module
If your ARN contains an optional, back-panel V.34 modem module, you need only
connect the telephone line to the V.34 interface for access to the router.
Table 1-5
provides the default settings for the back-panel V.34 modem adapter.
Note:
The default settings for the back-panel V.34 modem differ from the
default settings for the front-panel V.34 modem adapter module. Refer to
“Connecting to a V.34 Modem Interface” earlier in this chapter for information
about the V.34 modem adapter and its default settings.
Table 1-5.
