Introduction
The main field of application of Point-to-Multipoint (P-MP) systems is to provide access to both the Public
Switched Telephone Network (PSTN) and private networks (Private Digital Network (PDN)), particularly
for remote subscribers. By means of P-MP systems the network service area may be extended to cover
both distant and scattered subscriber locations.
These remote subscribers, in a similar manner to the city subscriber, are offered the full range of services
by the particular public or private network. Subscribers have access to these services by means of the
various standardized user network interfaces (2-wire loop, data, .).
P-MP applications in the metropolitan and urban environment are mainly for the provision of new data
services for business subscribers and for the extension of Integrated Services Digital Network (ISDN)
services to local subscribers.
The frequency bands below 3 GHz are particularly suitable for the extension of telecommunications
services to distant rural and suburban subscribers.
P-MP systems provide standard network interfaces and transparently connect subscribers to the
appropriate network node (local switch, .). These systems allow a service to be connected to a number
of subscribers ranging from a few users to several hundred and over a wide range of distances.
P-MP systems are generally, but not necessarily, configured as pre-assigned systems or as Demand
Assigned Multiple Access (DAMA) radio systems.
The essential features of a typical P-MP DAMA radio systems are:
- efficient use of the radio spectrum;
- concentration;
- transparency.
Radio is often the ideal way of obtaining communications at low cost and almost independent of distance
and difficult topology. Moreover, only a small number of sites are required for these installations, thus
facilitating rapid implementation and minimizing maintenance requirements of the systems.
Concentration means that N subscribers can share n channels (N being larger than n), allowing better use
to be made of the available frequency spectrum and at a lower equipment cost. The term "multi-access" is
derived from the fact that every subscriber has access to every channel (instead of a fixed assignment as
in most multiplex systems). When a call is initiated one of the available channels is allocated to it.
When the call is terminated, the channel is released for another call.

Concentration requires the use of distributed intelligent control which in turn allows many other operation
and maintenance functions to be added.
Transparency means that the exchange and the telephone communicate with each other without being
aware of the radio link.

1 Scope
1.1 Applications
The scope of this European Telecommunication Standard (ETS) covers the following Point-to-Multipoint
(P-MP) applications:
- voice;
- telex;
- low speed data (up to 64 kbit/s);
- Integrated Services Digital Network (ISDN) (basic rate access).
1.2 Frequencies
This ETS covers fixed P-MP services operating in the 1,5 GHz, 2,2 GHz, 2,4 GHz and 2,6 GHz bands and
having the frequency plans as given in CEPT Recommendation T/R 13-01 [1] for 1,5 GHz, 2,2 GHz and
2,6 GHz bands. For the 2,4 GHz band, the CCIR Recommendation F.701 [2] is applicable.
1.3 Access method
This ETS covers Time Division Multiple Access (TDMA) systems.
