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 global title is similar in purpose on the PSTN to the host name on the Internet.In design, however, global titles are quite different. The structure is usually hierarchical, the value can be of variable length, and is not necessarily a wholly numeric value—though it often is for issues of backward compatibility and association with regular telephone numbers.
Signalling System No. 7 (SS7) is a set of telephony signaling protocols developed in the 1970s that is used to setup and teardown telephone calls on most parts of the global public switched telephone network (PSTN).

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.
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.
SS7 is a centralized protocol, characterized by a complex central network architecture and dumb endpoints (traditional telephone handsets). SIP is a client-server protocol of equipotent peers. SIP features are implemented in the communicating endpoints, while the traditional SS7 architecture is in use only between switching centers.
In Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS), subsystem numbers may be used between Public land mobile networks (PLMNs), in which case they are taken from the globally standardized range (1 - 31) or the part of the national network range (129 - 150) reserved for GSM/UMTS use between PLMNs.
