System Configuration via an ISDN
Connection to ISDN is required to use the PCS-B768 ISDN Unit especially
designed for use with this system.

transmission by connecting up to six ISDN lines.

About the number of ISDN lines and B (bearer) channel
Up to six ISDN lines can be connected to one PCS-1/1P via the optional PCS-
B768 ISDN Unit. 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 six ISDN lines with the
PCS-1/1P and select the number of channels used for a single communication
among from 1B, 2B, 3B, 4B, 5B, 6B, 8B and 12B connections.
