To connect with a normal phone
When you are using an ISDN connection, a normal phone can be connected at
up to five points.
Only the 1B (64K) connection is available for a normal phone.
• When using the ISDN connection, installing the PCSA-MCG80 HD MCU software
in two or more Communication Systems does not allow cascade connection.
• For multipoint connection, only the Communication System with the PCSA-MCG80
HD MCU software installed can be used as main terminal. If you want to use two or
more Communication Systems as main terminals depending on the type of
connection, the same number of HD MCU software installations as that of main
terminals is required.
Using Both LAN and ISDN
Installing the PCSA-MCG80 HD MCU software in one HD Visual
Communication System enables a multipoint connection with the terminals
connected via a LAN and ISDN.
