CS - SMS-4 Short Message Service for CS8014

:·SMS-4 Short Message Service for CS8014

What SHORT MESSAGE SERVICE Offers

Now, with the option SMS-4, the CS8014 "Automatic FFT Telephone Test System" becomes able to test functionally the PSTN Telephone Equipments (TE) equipped with the Short Message Service function.

The Short Message Service via PSTN is a Service, launched on the market by some Telecom Operators, which provides the possibility for a Subscriber to send and receive Short Messages using specific telephone terminals. The connection from a source telephone to the destination telephone is not direct, but is made through a Short Message Service Centre, which stores the submitted messages and delivers them in a second time.

The ETSI Standard specifies protocols to provide this service on the fixed network. The transmission of messages of up to 160 characters is guaranteed, although much longer messages are possible.
The protocols specified in the ETSI Standard support a User Based Solution, where messages are transported via a Short Message Service Centre using a normal voice band call through the network using in band signalling.
SMS messages are sent via the Short Message Service Centre using a store-and-forward principle.
The Provider of the short message service does not necessarily have to be the operator of the public telecommunications network.

The ETSI Standard ES201 912 specifies two different protocols to provide the SMS over PSTN. Both protocols offer the opportunity to exchange Short Messages with other networks, e.g. GSM and with other services, e.g. Email, Fax.

Protocol 1:
has the advantage of being fully compliant with the GSM SMS service.

Protocol 2:
has the advantage that it specifically focuses on the residential fixed network environment.

SMS-4 option at present meets the above mentioned ETSI ES 201 912 regulation.

The Short Message exchange operates as follows:

Message submitted by a TE:
The TE actuates a standard DTMF dialling to establish the connection with the Service Centre. After received a connection confirmation, the TE send its message using FSK - ETS-300 778-2 protocol.
Message delivered to a TE:
TE must be in off-line condition. The SM Service Centre sends a CLI to the telephone, using the ETS-300 659-2 protocol, where the TAS is an RP-AS Ringing Pulse. After the above connection an FSK string is sent to the TE, including the Calling Party Number of the message. The CLI includes one additional digit having the meaning to identify one of up-to 9 TE connected to the same line. All telephones connected will receive the call, but one only will receive the message.

INCREASED TEST CAPABILITY OF CS8014

The above-mentioned NEW function, the SMS Option, can be installed on all CS8014 having the SIGNAL-OPTION+CLIP already present. The installation requires some changes in firmware and hardware of the CS8014 besides the upgrade of the WIN8014 software installed on the host Personal Computer. In addition, the host Personal Computer must have a second serial port (COM) to permit the connection of the SMS-4 external device, which completes the SMS-4 Option.

The upgraded CS8014 operates as a SM Service Centre: So it becomes able to activate the procedure for submission and delivering an SMS.

You can program a SMS Submitting Test by a panel, like the first picture, where the protocol parameters can be changed to verify the reception limits.

The user can program also the message, the Short Message Service Centre number and the type of message. A panel like the second picture, where you can define the message to be received, the destination address and the message type, can program the SMS Delivery Test.

The SMS Delivery Test is made as functional only. You will able to verify if your TE is able to send a message to the SM Service Centre and if the message will be received without errors.
