Appendix C: Command Line Reference Callback 166
Callback
SET CALLBACK MODE type option [number1 number2]
Valid context: Profile/PPP
Several callback modes are available. Each provides different features. For callback to work, both client and
server must use the same mode. The DIVA LAN ISDN Modem can only function as a callback client.
type: NONE, NCP, ISDN
NONE: No callback.
NCP: Supports both the USERSPEC and ADMINSPEC options. This is a Microsoft-developed solution. It is
used by NT4, and devices from Cisco, Ascend, and other vendors. NCP enables you to specify a time delay
before the server calls back.
ISDN: The server does not answer the initial call from the DIVA LAN ISDN Modem (thus there is no charge
for the call). The remote uses caller ID information to return the call. Only works with Cisco IOS.
option: USERSPEC, ADMINSPEC
USERSPEC: (user specified) The DIVA LAN ISDN Modem must supply the server with the callback number
to use. The number must include the appropriate dialing prefixes.
ADMINSPEC: (administer specified) The DIVA LAN ISDN Modem does not supply the server with a number
to dial, instead the server maintains its own table of numbers. The server identifies the DIVA LAN ISDN
Modem by its caller ID or user ID (supplied during call authentication). The server then uses this information
to determine which number to dial for callback.
number1: USERSPEC only. This is the first number that the server dials when calling back. It should be the
first ISDN number assigned to the DIVA LAN ISDN Modem, and include all required dialing pre-fixes.
number2: USERSPEC only. This is the second number that the server dials when calling back. For example, if
you have two ISDN numbers, and you want to establish an MLPPP connection, the server must call in twice,
once to establish each channel.
SET CALLBACK TIMEOUT seconds
Valid context: Profile/PPP
Sets the amount of time the DIVA LAN ISDN Modem waits for the server to call back. During this time, the
DIVA LAN ISDN Modem will refuse incoming calls that are not from the callback server on the phone number
that was configured for callback.
seconds: Length of delay in seconds. Range: 20 to 240. Default: 30.
SET CALLBACK DELAY seconds
Valid context: Profile/PPP
Callback control protocol only. Sets the amount of time the server waits before calling back. The DIVA LAN
ISDN Modem proposes the delay during callback negotiation. The server can either accept or reject it.
seconds: Length of delay in seconds. Range: 1 to 30. Default: 5.
SHOW CALLBACK CONFIGURATION
Valid context: Profile/PPP
Displays the current setting of all callback parameters for the current profile.
