■ Physical or Dialer Interface view
Description This command must be configured at the server end when ISDN caller ID is applied for
callback. In Resource-Shared DCC, because both PPP and frame relay protocols can be
encapsulated on dialer interfaces, ISDN interface can encapsulate link layer protocol
dynamically according to corresponding dialer interface.
The caller first searches corresponding dialer interface by matching the caller number
with the
dialer number command. The dialer call-in command is used to
preprocess the ISDN call-in number, determining whether the user with this number
can be permitted to access. If the PBX switch does not provide the caller number,
refuse the call directly.
