Filter editor: LCN value

Selecting conditions can be defined by value(s ). See features.
Counting specifications ( for Statistics ) can be defined by value(s ). See features.

Their use is based on the following rules:

  • The different selecting conditions in the panel are exclusive.
  • The auto mode is not available within a Display action (or Counter specifications).

LCN Value. A value condition can be directly edited in either decimal  mode or binary form (0, 1 and x for mask use).

  • Yes. The value condition is selected.
  • No. The value condition is not selected.

LCN Auto

A value condition can be indirectly defined.
  • Yes. The auto value condition is selected.
  • No. The auto value condition is not selected.

The value of the LCN to be used as a selecting condition is automatically determined from the monitoring of the protocol sequence upon recognition of a matching packet type with a Called/Calling address or a Facilities/User data content.

  • Packet. Access to the choice list of the packet types of the protocol layer. A packet type MUST be selected.
  • Called address. Value in digits.
    The Called/Calling address and the Facilities/User data content are linked with a logical OR operation.
  • Calling address. Value in digits. The Called/Calling address and the Facilities/User data content are linked with a logical OR operation.
  • Facilities.
    • User data Ascii... Edition in ASCII mode of a selecting string of bytes which must be a partial or the full content of the Facilities/User data of the selecting packet.
      The Called/Calling address and the Facilities/User data content are linked with a logical OR operation.
    • User data Hexa... Edition in hexadecimal mode of a selecting string of bytes which must be a partial or the full content of the Facilities/User data of the selecting packet.
      The Called/Calling address and the Facilities/User data content are linked with a logical OR operation.

When the matching condition occurs:

  • Only the packets with the related LCN value will be selected until the last one ending the call.
  • The automatic recognition becomes inactive until the last packet ending the call.
