Setting up standby or control channel over Dial-In server
Usage example description Purpose: setting up standby or control data channel over wireless or commute connections. A Dial-In server built into SG-17R helps to establish a link between the server and the users of the control centre using the "dial-in over modem" mode. After the link is established, the user may carry out terminal and web control over the SG-17R device. In this mode the user may complete any action needed to configure SG-17R, to access the statistics, etc. Moreover, if additional equipment is connected to the serial ports of SG-17R, such equipment may be operated in console mode without web-browser exit. If operator’s transport network is used, it is possible to establish a standby channel in case of any trouble in the main channel. In order to maintain operation of the system low-speed modems may be used for dedicated lines with RS232 ports that provide greater transmission distances. The maximal number of installed RS232 ports is 16. Different DTE/DCE operating modes are supported for successive modules. Along with linking up the equipment with serial channels any SG-17R interfaces may be used, for example to connect a local network, telephony or to link up voice frequency channels equipment.
