E.214 provides a method to convert the IMSI into a number that can be used for routing to international SS7 switches. E.214 can be interpreted as implying that there are two separate stages of conversion; first determine the MCC and convert to E.164 country calling code then determine MNC and convert to national network code for the carrier's ...
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.
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.
This indirect connection is called quasi-associated signaling, which reduces the number of SS7 links necessary to interconnect all switching exchanges and SCPs in an SS7 signaling network. [ 12 ] SS7 links at higher signaling capacity (1.536 and 1.984 Mbit/s, simply referred to as the 1.5 Mbit/s and 2.0 Mbit/s rates) are called high-speed links ...

The ISDN (Integrated Services Digital Network) User Part or ISUP is part of Signaling System No. 7 (SS7), which is used to set up telephone calls in the public switched telephone network (PSTN). It is specified by the ITU-T as part of the Q.76x series.
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.
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.
