What is ANSI Window Function in Wireshark ?

Wireshark is a packet sniffing and free open-source packet analysis tool. It captures network traffic on the local network and stores this data and displays the captured data for offline analysis. So, in this article, we will learn about the ANSI protocol and ANSI Window in Wireshark. and what are the components?

The Main Window of Wireshark

The main window of the Wireshark while the wireless fidelity capturing. As you can see in the below image there is a tool menu function, main toolbar function, packet list pane, and packet details pane. present the captured network interface.

ANSI Protocol

The ANSI protocol is the function of the Telephony Menu function that provides many functions which help to identify and troubleshoot VoIP and other telephony protocols like H.225 Window, VoIP Calls, MTP3, etc.

In Wireshark, ANSI protocols can include standards like ANSI X3.28, which defines the control sequences used for character-oriented terminal devices, or ANSI T1.403, which specifies the electrical characteristics of digital transmission systems.

ANSI Window

The ANSI Window in Wireshark refers to a set of or a collection of statistical data related to mobile communication protocols, specifically based on the European Telecommunications Standards Institute (ETSI) GSM standards. GSM (Global System for Mobile Communications) is a widely used standard for mobile telephony and data transmission.

ANSI Window Classified into two categories:

1. A-I/F BSMAP Statistics Window
2. A-I/F DTAP Statistics Window

A-I/F BSMAP Statistics Window

The A-Interface Base Management Application Section (BSMAP) Statistics window in Wireshark provides a comprehensive summary of captured messages related to the A-Interface BSMAP protocol. BSMAP is a routing protocol used in mobile networks to control and manage stations.

In the BSMAP Statistics window, you can view a list of messages captured while monitoring or analyzing network traffic. Each message represents a particular event or change of network elements involved in interface A communication.

A-I/F DTAP Statistics Window

The A-Interface Direct Transfer Application Part (DTAP) Statistics window in Wireshark provides a comprehensive overview of the captured messages related to the A-Interface DTAP protocol. DTAP is a signaling protocol used in mobile networks for the exchange of non-circuit-related signaling messages between the Mobile Switching Center (MSC) and the Base Station System (BSS).

Within the DTAP Statistics window, you can observe a list of the captured messages, representing various signaling exchanges between the MSC and the BSS. Each message in the list includes information such as the message type, source and destination addresses, timestamp, and other relevant details.

Overall, the ANSI Windows in Wireshark, specifically tailored to the ETSI GSM standards, serves as a valuable resource for network engineers, operators, and analysts working with GSM-based mobile networks.
