… Frequently used settings for PLC-systems PSTN Network Most PLC-systems and other industrial applications where modems are used require the same changes to the standard settings. The most commonly encountered problems concern speed, parity and control signals from the connected equipment. If this action does not solve the problem the modem’s answering codes and possible echoing of commands might be the source of the difficulty. Below follows a list of commands that might resolve the problems.
… TDW-33 – Secure Call-back The TDW-33 is connected to a PLC which one want to restrict access to. The TDW-33 can support access control through the Secure Callback function. In this example password and callback to a predefined number is chosen. The modem in the calling end is here chosen to be a PSTN modem, but can be any of the PSTN, ISDN or GSM modem from the Westermo product range.

… TDW-33 – Silent answering on predefined number The TDW-33 is connected to a power meter which is remotely monitored. The TDW-33 shares the PSTN line with normal telephones which is preferred not to give a ring signal when the meter is read.
