Calls from an ISDN terminal are then automatically connected to the LE of the ISDN network. The bypass may
also be activated manually.
in the boxes refer to the IC-4BRV's four BRI port numbers.

Network integration

With the configuration options tabulated above 4 BRI ports of the IC-4BRV can be connected in one of three
network configurations:
• All four ports (ports 0–3) are connected to a subscriber PBX as shown in
• Three ports (0, 1, 3) are connected to the PBX and one port (2) to the ISDN network (local breakout) as
shown in figure 19 on page 40. The local breakout port can be used to route calls from and to the ISDN
network. This is the fallback situation described in section
fails or the bypass is manually activated, ports 1 and 2 are inter-connected through the bypass relay, provid-
ing a lifeline to the ISDN network.
• Two ports (0, 1) are connected to the PBX and two ports (2, 3) to the ISDN network (see
page 41. In this case, both local breakout ports (four B-channels) can be used to route calls to the ISDN
network. Only port 1 is protected by the bypass relay.
