Features
Data Modules
Data modules connect DEFINITY ECS with other communications equipment, changing protocol, connections, and timing as necessary.
DEFINITY ECS supports the following types of data module:
■High Speed Links
■Data stands
■
■
■
■Asynchronous Data Unit
■Asynchronous Data Module (for
■Terminal adapters
All of these data modules support industry standards and include options for setting the operating profile to match that of the data equipment.
Modem Pooling
Enables switched connections between digital data endpoints (data modules) and analog data endpoints and acoustic coupled modems. Data transmission between a digital data endpoint and an analog endpoint requires a conversion since the DCP format used by the data module is not compatible with the modulated signals of an analog modem. A modem translates DCP format into modulated signals and vice versa. The Modem Pooling feature provides a set of modems for such conversions.
DEFINITY ECS modem pools are assigned into modem pool groups. A group can have up to 32 modems, called “members.” DEFINITY ECS can have as many as 63 modem pool groups. See Figure 9.
