1 Scope
The present document specifies the minimum performance parameters for terrestrial digital fixed service radio
communications equipments operating in the 15 GHz to 38 GHz frequency band intended to be used for point-to-point
connections in local and regional networks at data rates between 2 × STM-1 (transported by one carrier) and 4 × STM-1
or STM-4 (transported by two 2 × STM-1 carriers).
Harmonized channel spacings of 56 MHz are not available in frequency bands below 15 GHz at the drafting date of the
present document. However, the present document can be considered as a guideline where national frequency plans
allow the use of 55/56 MHz channel spacing in other frequency bands, or where an allocation of two contiguous
28 MHz channels is possible.
The maximum transmission rate in a given bandwidth depends on system spectral efficiency, a single equipment class is
defined:
Class 5: equipment spectral efficiency based on typically 128-states modulation scheme (e.g. 128-QAM,
or equivalent).
However, for addressing different market requirements, the systems are further subdivided in two grades:
a) Adjacent Channel Alternate Polarization (ACAP as class 5a).
b) Adjacent Channel Co-Polarization (ACCP or CCDP as class 5b).
The above classes are indicative only and do not imply any constraint to the actual modulation format, provided that all
the requirements in the present document are met.
Examples of the spectrum usage are given in figure 1.
The 4 × STM-1 or STM-4 connection is achieved by two 2 × STM-1 carriers. The two carriers can be arranged in three
configurations:
a) Adjacent Channel Alternate Polarization for which ACAP, class 5a is applicable.
b) Adjacent Channel Co-polarization for which ACCP, class 5b is applicable.
c) Co-Channel Dual Polarization for which CCDP, class 5b is applicable. For this configuration, XPIC may be
used.
Examples of the three spectrum usage of a 4 × STM-1 or STM-4 system are given in figures 1a, 1b, and 1c.
A 2 × STM-1 system is achieved by using one single carrier in 55/56 MHz from any of the configurations in figure 1;
the system shall comply with the relevant spectrum efficiency classes (5a or 5b).

NOTE 1: For practical reasons, for configurations in figure 1a and 1b, it may be required to separate the two carriers
due to spectrum availability. However, in all cases the two carriers system is required to be capable of
operating in at least one of the configurations shown above.
NOTE 2: Due to the internal functionality of the cross-polar interference canceller (XPIC) equipment on both
polarization of the same channel is considered to form a single CCDP system according to figure 1c.

The present document, defines the parameters for 2 × STM-1 (311 Mbit/s) carriers. The performance of a 4 × STM-1 or
STM-4 system will be directly implicated from this definition, according to the spectrum efficiency classes 5a and 5b.
The parameters to be specified fall into two categories:
a) Parameters that are required to provide compatibility between channels from different sources of equipment on
the same route, connected to separate antennas.
b) Parameters defining the transmission quality of the proposed system.
The present document does not contain aspects related to test procedures and test conditions however they are to be
found in EN 301 126-1 [9].
Safety aspects are outside the mandate of ETSI and they will not be considered in the present document. However
compliance to EN 60950 [47] will be required to comply with Directive 1999/5/EC (R&TTE Directive) [8].
Technical background for most of the parameters and requirements referred in the present document may be found in
TR 101 036-1 [45].
