ISDN provides two basic types of interfaces to users.

 

  1. Basic Rate Interface (BRI)
  2. Primary Rate Interface (PRI)

Another big wireless network category is ad-hoc networks, where the infrastructure is composed as resorts themselves. The latter agreed to play the role of the router to allow the passages of information from one device to another, without these terminals are connected directly.

Products for ISDN technology from different vendors even with similar features and options may create some compatibility issues. CCITT after good deliberations over the years published the first significant ISDN standards in a number of red binders in 1984 and they were simply known as the Red Book standards. The group subsequently met four years later which culminated in the publication of the 1988 Blue Book standards. These international publications were the foundation for the evolving ISDN national standards. The CCITT eventually was reformed into the group, which is now called the ITU- T. The standards used to define ISDN make use of the OSI reference model with the first three layers of this OSI reference model.

• Session Initiation Protocol (SIP) was designed by IETF and is described in RFC 3261.

SONET (Synchronous Optical Network) is a proposal by Bellcore (Bell Communications Research), SONET is a technique of transport between two nodes, which defines the interface adopted for the NNI (Network Node Interface). She initially concerned that the interconnection of telephone networks of major operators, PTT, carrier, etc. The difficulty of standardization has been to find a compromise between the American, European and Japanese interests to interconnect different operator networks and national networks.

(xDSL) A whole class of digital telecommunication technologies that can offer BROADBAND data rates, up to 50 megabits per second (Mbps), over the existing copper wires of the analogue public telephone system. By employing advanced modulation schemes, xDSL technologies support Internet or other data access simultaneously with voice telephone calls. In the meta-acronym xDSL, the x stands for the first letter of any of the individual acronyms used for these technologies: ADSL, HDSL, SDSL and VDSL.

When data is sent to the receiver, flow control should be carried out so that the flow of data does not overwhelm the receiver. Any receiving device has a limited speed at which it can process the incoming data and a limited amount of memory to store the incoming data. The receiving device should be able to inform the sending device before these limits are reached so that the transmission is stopped or reduced, temporarily.

Routing is the primary element of an ad-hoc network. It takes routing software in each network node to manage the transfer of IP packets. The simplest solution is obviously to have a direct routing, as illustrated in Figure, in which each network station can directly reach another station, without going through an intermediary. The simplest case corresponds to a small cell, with a diameter less than 100 m, as in an 802.11 network in ad-hoc mode.

Wireless networks are developing due to the flexibility of their interface, which allows a user to change positions while staying connected. Communications between terminals can be made directly or via base stations, called access points, or AP (Access Point). Communication between access points can be wireless or cable. The flow rates of these networks are tens of megabits per second.
