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.
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.

The design of SS7 was influenced by the 6K, an electric locomotive model imported from Japan. [1] The first SS7 was built in 1992 in Datong. In 1997, SS7s were used in Nanning-Kunming Railway. However, SS7's frequent failure lead to Datong Electric Locomotive Works making improvements to SS7s. Failure was reduced to just four cases in one year ...

EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames.
