Connection to ISDN is required to use the PCSA-B384S or PCSA-B768S
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 PCSA-
B384S) or by connecting up to six ISDN lines (when using the PCSA-
B768S).
System configuration
About the number of ISDN lines and B (bearer) channel
Up to three ISDN lines with the PCSA-B384S ISDN Unit or up to six ISDN lines
with the PCSA-B768S ISDN Unit can be connected to one PCS-TL50
.
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.
When using the PCSA-B384S, you can connect up to three ISDN lines 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 PCSA-B768S, 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.
