Telephone transmission in MORSE

Print version

5. Telephone transmission in MORSE

There are several examples of a telephone network appearing in the MORSE system:

5.1. Connection of two PLCs over the MORSE network

It is used with the Hayes protocol as an alternative to telephone modems and a telephone network.

Direct connection of two PLCs

Connection over a telephone network and TM telephone modems

Connection over the MORSE network

The block CU-MORSE network-CU behaves in the same way as block TM-telephone network-TM and replaces the link between both PLCs. Data is transmitted through the MORSE network in packets as opposed to connection-oriented transmission over the telephone network. For a more detailed description see Hayes protocol for MORSE.

5.2. Connection between two CUs over a telephone network

This is used in the case of servicing a CU which is out of reach of a MORSE network.

Direct connection of two CUs

Connection over a telephone network and TM telephone modems

Service connection of two CUs over a telephone network

CUs with MARS-A protocols can communicate this way through telephone modems via a telephone network. This is used occasionally for servicing. The use of a telephone line is not suitable for normal data transmission. For a more detailed description see the MARS-A protocol description, chapter Connection via telephone or GSM modem.


5.3. Data transmission over a GPRS network

MG100 is a MORSE communication unit which uses a GPRS module in place of a standard radio part. It transmits data over a GSM mobile telephone network. For a more detailed description see GPRS modem MG100.

5.4. Service cable – remote access

Connection between PC and CU via a service cable

Standard connection between Setr and CU used for configuring the CU.

Connection between PC and remote CU over MORSE network

This is used for service access to a remote, unconfigured CU2 via CU1, which is accessible via MORSE routing. A more detailed description is given in chapter Local mode in the MORSE guide.

Connection between PC and remote CU over a telephone network

This is used for service access to a remote, unconfigured CU using a telephone modem. The remote CU can have default settings, however, the only necessary parameter is (R)emote dial-up in the MARS-A protocol. For a more detailed description see the (R)emote dial-up access chapter in the MARS-A protocol description.
