This chapter describes a new scenario for how to transform the existing telephone access network into a real broadband network. The objective is to introduce a low-cost network evolution scenario, which makes maximal use of the huge investments associated with this kind of network. The existing network is sub-divided into a small cell network, each covering an area with an approximate radius of...

OBJECTIVES To characterize variation in pediatricians' telephone referral practices, to identify differences in the types of referrals made during telephone versus office visit encounters, and to examine the impact of referring by telephone on coordination and outcomes of the referral as assessed by physicians. METHODS We conducted a prospective study of a consecutive sample of referrals (N =...

Network operators have long striven to utilize equipment from multiple vendors to drive down costs. Furthermore, in competitive environments, operators have separated out functions of network elements and distributed them in order to differentiate the offered services. This trend began with deregulation in the telephone industry and promises to accelerate in the Internet age.

In this paper we present the telephone network and the recommendations, dealing with the greatest target values of Post Selection Delay. It is shown that the Post Selection Delay is the sum of the delays between the network nodes and that it has the smaller dispersion than the one, recommended as the greatest in the recommendations.

VoIP (Voice over IP) over mesh networks could be a potential solution to the high cost of making phone calls in most parts of Africa. The Village Telco (VT) is an easy to use and scalable VoIP over meshed WLAN (Wireless Local Area Network) telephone infrastructure. It uses a mesh network of mesh potatoes to form a peer-to-peer network to relay telephone calls without landlines or cell phone tow...

SS7 is a signaling system for the public switched telephone network (PSTN) [1,2,3]. SS7 network transports call setup, teardown messages, database queries, trunk status, instructions for remote phone switches and so on, in fact it acts as a glue for the circuit switched networks. Before the deregulation act it was envisioned as a closed community network. After the deregulation, landscape has c...

A dynamic window model is developed which provides admission control for circuit switched networks through the signalling network. This model incorporates distributed processing while achieving desired global congestion control effects. It reflects the interaction between the circuit switched path in the telephone network and the packet switched path in the signalling network. The model is solv...

James J. McAndrews* Networks play an integral part in the production and consumption of certain goods and services, including transportation, communications, and payment systems. A network good or service has two main characteristics: the value a person gets from the product increases as more people consume it and the technique a firm chooses to produce the product will depend on techniques cho...
