CCITT is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The Plenary Assembly of CCITT which meets every four years, establishes the topics for study and approves Recommendations prepared by its Study Groups. The approval of Recommendations by the members of CCITT between Plenary Assemblies is covered by the procedure laid down in CCITT Resolution No. 2 (Melbourne, 1988). Recommendation E.173 was prepared by Study Group II and was approved under the Resolution No. 2 procedure on the 23rd of August 1991. ___________________ CCITT NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency. © ITU 1991 All rights reserved.

Recommendation E.173 Recommendation E.173 ROUTING PLAN FOR INTERCONNECTION BETWEEN PUBLIC LAND MOBILE NETWORKS AND FIXED TERMINAL NETWORKS 1 Introduction 1.1 With the worldwide introduction of public land mobile service there exists a need for interconnection between public land mobile networks (PLMN) and fixed terminal networks (e.g. PSTN/ISDN and PSPDN). 1.2 This Recommendation covers the routing plan for interconnection between PLMN and the public switched telephone network/integrated services digital network (PSTN/ISDN) and between PLMN and the public data networks (PDN). 1.3 It provides guidelines for routing when interconnecting PLMN and fixed terminal networks, and indicates some basic rules for routing of calls between the networks. Routing between networks must adhere to regulatory conditions which exist within a given country or Administration. Bilateral agreements may be required to establish the actual interconnection arrangements between network operators. 1.4 This Recommendation covers terrestrial-based PLMNs. Satellite-based PLMNs are for further study. 1.5 Routing requirements within fixed terminal networks are described in the following Recommendations: E.171 International telephone routing plan; E.172 Call routing in the ISDN era; X.110 International routing principles and routing plan for public data networks; G.173 (Draft) Transmission planning aspects of the speech service in digital public land mobile networks. 2 Terminology CSPDN Circuit swiched public data network DCME Digital circuit multiplexing equipment DSI Digital speech interpolation DTEData terminal equipment FDTE Fixed data terminal equipment, e.g. a DTE connected to the (PDN) IDSE International data switching exchange ISC International switching centre ISDN Integrated services digital network (within this Recommendation ISDN means the circuit switched part of the network; for the packet switched part see PDN) LMDTE Land mobile data terminal equipment, e.g. a DTE connected to PLMN LMS Land mobile station LRE Low rate encoding MSC Mobile switching centre (this is a centre that handles mobile traffic) Recommendation E.173 1 PDN Public data network, e.g. CSPDN, PSPDN or PHPDN in ISDN PHPDN Packet handler public data network PLMN Public land mobile network PSPDN Packet switched public data network PSTN QOS Quality of service TASI Time assignment speech interpolation TE 3 Public switched telephone network Terminal equipment Scope 3.1 This Recommendation includes the routing of calls between users of PLMN and the users of PSTN/ISDN or PDN. The term “call” encompasses all types of user-to-user communication, e.g. normal speech calls, data calls, text messages and emergency calls. 3.2 The following interconnection cases are considered: PLMN <–––> PSTN/ISDN (see Note 1) PLMN <–––> PSTN/ISDN <–––> PLMN (see Note 1) PLMN <–––> PDN (see Note 2) PLMN <–––> PDN <–––> PLMN (see Note 2) PLMN <–––> PSTN/ISDN <–––> PDN (see Note 2) PLMN <–––> PSTN/ISDN <–––> PDN <–––> PSTN/ISDN <–––> PLMN (see Note 2) Note 1 – The abbreviation PSTN/ISDN means one or more networks of the same type in series. Note 2 – The abbreviation PDN means one or more networks of the same type in
