OSCAR Open Signal Computing and Analysis Resource. An OSCAR
resource consists of Windows 2000 OSCAR node on which
algorithms such as speech synthesis, speech recognition, and the
Internet Audio Server allow speech-based transaction processing. The
Avaya MPS node with which the OSCAR node is associated can be a
Solaris or Windows 2000 node.
The MPS node provides telephony and application processing
services. The OSCAR node provides resource processing such as
speech recognition and synthesis. Avaya supports OSCAR speech
synthesis and recognition resources provided by multiple third- party
vendors and also provides an Internet Audio Server resource.
For additional information about the OSCAR resource, refer the
Avaya Media Processing Server (Avaya MPS) Series OSCAR 6.0.1
Reference Guide.

out-of-band signaling The phone line communication scheme where the dialing and
supervisory signals are separate from data transmission. All signaling
information for a group of lines (23 per T1 span, 29 per E1 span) is
carried on a single dedicated channel known as the D-channel. The
other channels (B-channels) carry the data for that line. With out-of-
band signaling, data is transmitted distortion free.
Out-of-band signaling decreases a span’s caller line capacity by one
line. One line is required to carry the signaling information for the
other lines. One D-channel can carry the signaling information for 2
spans.
The Avaya MPS uses ISDN for out-of-band signaling.
Contrast with in-band signaling.

Manual.
