the unit is ready to send data. If CTS remains off, check the
Forced RTS, Circuit Assurance and Anti-Stream settings.

If CD is not lit, there is no valid carrier signal detected.

operation, from the remote Model 2500RC Series). If NS is lit,
check for an unplugged cable, broken wire or an incorrect Line
Rate selection.
• “OS” glows red to indicate Out-of-Service. This means the
Model 2500RC Series has received an Out-of-Service signal
from the digital service provider and indicates a problem with
the service provider’s equipment. If this condition persists,
contact your service provider.
• “ER” glows red to indicate that an Error has been detected in
the received signal. ER will flash if the Model 2500RC Series
receives illegal bi-polar violations or framing errors. During the

Detector has detected a bit error.
