PA-8ILCE-A
ISDN Terminal Line Circuit
OFF
• Short Passive Bus mode: This mode is also a point-to-multipoint mode, in which a maximum of eight terminals can be
connected anywhere on the bus. Note that the bus length is limited to 200 m in this case.
• Extended Passive Bus mode: This mode is a point-to-multipoint mode, in which up to eight terminals can be connected.
Note that the terminals must be connected within 50 m from the end of the bus cables as shown below.
