CallPilot SMDI Link interface requirements
CallPilot SMDI link RS-232 demarcation point
The demarcation point of the CallPilot SMDI Link is the point at which the
RS-232 interface of the CallPilot server terminates in an RS-232 connector
for external equipment attachment.
The CallPilot SMDI Link external equipment requirements are specified
with two industry standards for all CallPilot applications and configurations.
An installation can employ whatever modem type (or no modem) meets the
particular application criteria (for example, modulation scheme,
interoperability, familiarity, reliability, product longevity, and cost).
