Netopia Router PN Series - Manual (Page 181)

Token Security Authentication 8-9
Note: When using CACHE-TOKEN, your passcode is valid for a time
interval determined by the network administrator. When this time
interval expires, you must provide a new passcode for the call
negotiation.
When using PAP-TOKEN for a 2B-Channel call, your passcode is valid
for one call negotiation. For a second call negotiation, you must
enter the next passcode provided by the security authentication
token card every 60 seconds.
You will be able to access information at the remote site that you
are connecting to once authentication is successfully completed.
Troubleshooting
If the security authentication process did not negotiate properly,
check for the following:
■ If your security authentication token card is providing you with a
passcode but is being rejected by the Radius server, your token
card may be out of sync with the Radius server, or the server is
not correctly configured to accept your account information.
■ If your security authentication token card is not providing you
with a passcode, the card may have expired or either the
Netopia Router or Radius server is misconfigured.
For further information on how to troubleshoot these kinds of
problems, contact the manufacturer of your security authentication
software and hardware, or contact Farallon Technical Support.
