Modems serve a variety of features in control systems, including communicating with I/O devices, providing a connection method for remote VTS application clients and disseminating messages from the VTS Alarm Dialer.
Modem Pooling
Since VTS handles different types of modems in a different ways, modem management must receive close attention. VTS needs to be able to determine which of the modems is capable of handling each type of communication and direct modem traffic appropriately.
This process is called modem pooling and it allows VTS to manage a group (pool) of modems efficiently. When a modem is required for an outgoing voice call from the VTS Alarm Dialer, the VTS Modem Manager automatically searches its pool of modems for the next available modem capable of handling a voice call.
The same process is followed for outgoing data calls. Similarly, any pooled modem can be configured to allow or deny incoming voice or data calls.
- Supports modem pooling across servers for improved resource efficiency.
- Includes custom Unimodem driver.
- Data and VTS Alarm Dialer requests are automatically routed to appropriate voice and data modem(s). No configuration necessary.
- Supports dedicated modems for functional application areas.
- Supports logging of modem activities.
- Graphics show modem events, usage statistics and modem status.
