System Outline of ISDN-BRI

The system is configured with a Basic Rate Interface Trunk (BRT) for the digital network interface. Since
the MP contains PLO, the system can be synchronized to the ISDN as a clock receiver office.
The figure below shows the system outline of ISDN-BRI.

NOTE 1: NT1 equipment must be installed in the premise.
NOTE 2: We recommend the point-to-point connection when connecting the system to the public network
using the BRT card (Set the second data of CM35 Y=79 to 0).
For the point-to-multipoint connection using the BRT card, when the system is established far
from the public network, the communication error occurs easily because the ISDN signal fades
away.
