The ISDN dissector is partially functional. It assumes that it is supplied with a frame for some protocol layer (such as ["LAPD"] on a D-channel, or a protocol such as ["PPP"] on a B-channel), ,and an indication of the channel, displays the channel number, and dissects all D-channel traffic as ["Q.931"]. It attempts to guess whether B-channel traffic is ["V.120"] or ["PPP"]; it could perhaps be enhanced either to attempt to guess other traffic types or to allow a traffic type to be specified by a preference.

Integrated Services Digital Network (ISDN)

XXX - add a brief ISDN description here

History

XXX - add a brief description of ISDN history

Protocol dependencies

ISDN runs on top of the hardware supplying time-domain-multiplexed channels on a BRI or PRI line, so it depends only on hardware.

Example traffic

XXX - Add example traffic here (as plain text or Wireshark screenshot).

Wireshark

The ISDN dissector is partially functional. It assumes that it is supplied with a frame for some protocol layer (such as LAPD on a D-channel, or a protocol such as PPP on a B-channel), ,and an indication of the channel, displays the channel number, and dissects all D-channel traffic as Q.931. It attempts to guess whether B-channel traffic is V.120 or PPP; it could perhaps be enhanced either to attempt to guess other traffic types or to allow a traffic type to be specified by a preference.

Preference Settings

There are no ISDN specific preference settings.

Example capture file

Display Filter

A complete list of ISDN display filter fields can be found in the display filter reference

  • Show only the ISDN based traffic:

Capture Filter

As Wireshark doesn't support capturing raw ISDN traffic, there are no capture filters for it.
