16 System Configuration
Connection to ISDN is required to use the PCS-B384 or PCS-B768 ISDN Unit
especially designed for use with this system.
This allows you:
• To hold a point-to-point videoconference over ISDN.
• To show still images stored in a “Memory Stick”.
• To hold a videoconference with high speeds and highest quality image
transmission by connecting up to three ISDN lines (when using the PCS-
B384) or by connecting up to six ISDN lines (when using the PCS-B768).
System configuration
About the number of ISDN lines and B (bearer) channel
Up to three ISDN lines with the PCS-B384 ISDN Unit or up to six ISDN lines with
the PCS-B768 ISDN Unit can be connected to one PCS-1/1P
. Each ISDN line is
composed of two B channels that carry data signals on the ISDN interface,
enabling both channels to be used for one ISDN line connection (2B
connection), or each for a separate ISDN line connection (1B connection). The
more channels you use for a single communication, the faster speeds and
higher-quality picture you can obtain for your network communication. You
can connect up to three ISDN lines with the PCS-B384 and select the number
of channels used for a single communication from among 1B (64K), 2B
(128K), 3B (192K), 4B (256K), 5B (320K) and 6B (384K) connections. When
using the PCS-B768, you can connect up to six ISDN lines and select the
number of channels from among 1B (64K), 2B (128K), 3B (192K), 4B (256K),
5B (320K) and 6B (384K), 8B (512K) and 12B (768K) connections.
