While the MAP 3GPP specifications make some effort to divorce MAP from the layer that transports it, the typical transport is via TCAP which in turn is via SCCP/MTP[1-3] and/or SIGTRAN protocols (SUA, M3UA etc.). A MAP_OPEN construct therefore is directly related to a TCAP_BEGIN with a MAP application context, a MAP_CLOSE is a TCAP_END.
An SS7 probe is a physical device to obtain signalling and/or bearer information from a telecommunications network, such as the PSTN or a corporate telephone system. The probe passively monitors the E1 / T1 or SDH / SONET bearer channels, and extracts the signalling information for onward presentation to an application.
In mobile telecommunications network routing, E.214 is one of three prevailing numbering plans used for delivering mobility management related messages. [1]The E.164 numbering plan, which is a maximum of 15 digits and usually written with a "+" prefix, is the historic first-generation format representing the phone number.
The Message Transfer Part (MTP) is part of the Signaling System 7 (SS7) used for communication in Public Switched Telephone Networks. MTP is responsible for reliable, unduplicated and in-sequence transport of SS7 messages between communication partners. MTP is formally defined primarily in ITU-T recommendations Q.701, Q.702, Q.703, Q.704 and Q.705.
Ethernet packet. The SFD (start frame delimiter) marks the end of the packet preamble. It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport

Generic 802.11 Frame. The very first two octets transmitted by a station are the Frame Control. The first three subfields within the frame control and the last field are always present in all types of 802.11 frames. These three subfields consist of two bits Protocol Version subfield, two bits Type subfield, and four bits Subtype subfield.
SS7 or SS-7 may refer to: Signalling System No. 7, a set of telephony signalling protocols; SS-7 Saddler, the NATO reporting name of R-16 missile;
