Cisco AS5300 Configuration 2-15
Verify
Verify
To verify the configuration:
• Launch a voice call into the access server using a standard POTS telephone. If you hear modem
squelch (tone) from the access server’s internal modem, the configuration works. See Figure 2-2.
Figure 2-2 Voice Test Call
• Enter the show interface serial 0:23 command. The term “spoofing” means that the interface is
presenting itself to the Cisco IOS software as up and operational. This interface can now receive
routes. There are 23 more channels behind this interface that you do not see (for example, S0:0,
S0:1, and so on). The D channel decides which serial channel to assign to an incoming call.
