CHAPTER 1 GENERAL INFORMATION
SYSTEM OUTLINE
NOTE 3:
When connecting the system to the public network by the point-to-multipoint connection that the
plural ISDN terminals and the system use the same B-channels as shown below, during the B-
channels are used by the ISDN terminals, the terminals in the system cannot call to the outside
party (receive ROT, if they call) even if the B-channels of BRT card are idle. Because the system
cannot recognize that the B-channels are used by ISDN terminals.
Therefore, divide the B-channels into the system and ISDN terminals or use the D-channel
packet for the communication of ISDN terminals.
