This part of the seven part European Telecommunication Standard (ETS) 300 133 defines the receiver
conformance specification which the different categories of paging receiver must comply with before they
can be operated on the European Radio Message System (ERMES). Essential features are covered which
make up the basic version receiver of each paging receiver category and also the optional receiver
features which, if implemented, must conform to this specification.

weaker and 30 Hz RF frequency offset shall be added. The reference test procedure is given in
Annex A, Clause A.8;
l) channel switching: The average usable sensitivity shall be measured with the following test signal: A
batch shall be transmitted consisting of 139 initial addresses numerically higher than the initial
address of the receiver under test. This shall be immediately followed by the test message shown in
subclause 8.1.1 transmitted on the appropriate channel (see ETS 300 133-4 [1], figure 2). Both shall
be of the same batch type (i.e. same batch number), within the same subsequence and neither shall
contain the home operator identity.
7 User functions
7.1 General
Receiver functions are qualified as essential or optional.
Essential functions shall be implemented in so far as they are relevant to the particular receiver paging
category and shall be subject to type approval. Implementation of optional functions shall be left to the
manufacturers' discretion.
The basic version receiver within each receiver paging category is the receiver offering only the essential
functions.
Additional functions not mentioned in this standard are permitted provided that they do not conflict with the
radio interface and do not adversely affect the functions listed in this standard.
Any additional functions incorporated into the receiver shall be declared by the manufacturer.
Each receiver shall be individually identifiable.
7.2 Radio Identity Code
Each receiver shall have one basic Radio Identity Code (RIC).
Further additional RICs may be incorporated so long as the full receiver specification is satisfied for each
RIC.
Discrimination between calls on different RICs shall be offered.

Bit and word synchronisation shall not be maintained between channels and at least two transmissions
shall be at the extreme of allowable network co-ordination (see ETS 300 133-4 [1], subclause 13.4).
8.2.2 Recognition of zone code
A transmission shall be constructed which contains a message to a home receiver with the same local
address as the receiver under test. The zone code in the SSI word shall be different from the home zone
of the receiver. The receiver shall not receive the message.
8.2.3 Two messages in the same batch
The receiver shall successfully receive a message when the batch also contains a message to a home
receiver with the same local address. A transmission shall be constructed as below. Message 1 is for the
home receiver, message 2 is for the external receiver under test.
NOTE: The PAD in this case will be an initial address lower than that of the receiver under test.

8.2.4 Message reception in overlap regions (BAI=1)
A continuous transmission indicating the home network shall be sent to the receiver. The BAI shall be set
to one. The receiver shall then successfully receive an external message on another channel as illustrated
below.

8.2.5 Message reception in overlap regions (BAI=0)
A continuous transmission indicating the home network shall be sent to the receiver. The BAI shall be set
to zero. The reception quality on the channel shall then be reduced to a level corresponding to a call
success rate not less than 60 %. The receiver shall then successfully receive an external message on
another channel as illustrated below.

The message shall be split equally between the end of the first batch and the start of the next batch.
The message shall consist of every character specified in Annex C except DC1, repeated as necessary to
form a 400 character message. The receiver shall be examined to ensure the characters have been
presented correctly. The control characters ESC, LF, and CR shall not cause any character to be
displayed. If the control characters are used in conjunction with any other characters specified by the
manufacturer, these combinations shall not be sent for this test.
8.4 Alert function
A message as defined in subclause 8.1.1 shall be sent to the receiver. The receiver shall successfully
receive the message.
8.4.1 Normal operation
The receiver shall give an alert when the alert signal indicator bits in the message header are set to 000.
The other alert bit combinations shall also be tested. If the receiver gives an alert to one or more of them,
the alerts shall be clearly distinguishable.
8.4.2 Silent mode operation
The receiver shall have a switch by which it can be set to silent mode i.e. no audible alert given.
The silent mode shall not affect the receiver's other operations. The effect of all alert bit combinations in
the silent mode shall be tested and compared to normal operation as defined in subclause 8.4.1.
8.5 Termination of numeric messages
A receiver offering a numeric feature shall not present any character of the numeric message after having
received a codeword in error.
A message as defined in subclause 8.1.1 shall be sent to the receiver. The receiver shall successfully
receive the message.
In the message part after the message header, 18 numeric characters shall be transmitted namely
123456789012345678. The second codeword shall contain three bits in error. The receiver shall present
characters 1234. In the message header the external bit and All shall both be set to zero.
