Communication control system
First Claim
1. A communication control system having a rescue architecture comprising:
- a rescue bus connected to units in a multiple formation;
switch parts each including a line switch, a rescue bus connection switch and a rescue switch, the line switch connecting a signal in a channel on a line and a signal processing part that processes the signal in normal operation and disconnecting the signal from the signal processing part when a fault has occurred, the rescue bus connecting switch connecting the line and the rescue bus when the fault has occurred, the rescue switch connecting the rescue bus and a backup signal processing part that processes the signal instead of a faulty unit that is one of the units in which the fault has occurred;
at least one communication unit including one of said switch parts and said signal processing part;
a rescue unit including another one of said switch parts and said backup signal processing part and performing at least one of a complete rescue based on a unit basis and a provisional rescue based on a channel basis; and
a monitor control device monitoring occurrence of a fault and perform switch control of the switch parts.

Abstract
A communication control system equipped with an efficient and economical rescue architecture is provided. A rescue bus is connected to units in a multiple formation and is used for rescue from a fault. A line switch connects a signal in a channel on a line and a signal processing part that processes the signal in normal operation, and disconnects the signal from the signal processing part when a fault has occurred. A rescue bus connecting switch connects the line and the rescue bus when the fault has occurred. A rescue switch connects the rescue bus and a backup signal processing part that processes the signal instead of a faulty unit. A communication units includes a switch part made up of the above switches and the signal processing part. A rescue unit includes a switch part made up of the above switches and the backup signal processing part, and performs a complete rescue or a provisional rescue. A monitor control device monitors fault occurrence and controls the switch part.
