Single Bandwidth Each Signal Time Bus consists of 32 channels. Data Bus carries traffic at the rate of 64 Kbps. Control Bus carries maintenance information. The one ST Bus can accommodate no more than 32, 64 Kbps circuit, this is called single bandwidth. (8 x 2M) = 16 Mb.DXUniversal Card SlotData BusControl Bus AControl Bus B

Control Packet Switching System (CPSS) Newbridge proprietary - based on X.25 protocol.

Control Packet Switching System (CPSS) is a Newbridge proprietary system based on the X.25 protocol used for network management.

Used for carrying network information and control.It is used for carrying network information and control commands around the network.

Needs to be present on connections to all nodes.CPSS needs to be configured on links for all nodes that are to be managed by a network manager. Redundancy needs to be built in to ensure that network management can still take place even if one of the links fails

Control Packet Switching System (CPSS) Types of CPSS : Dedicated CPSS, which is generally used between nodes for network management Shared CPSS, which is used mainly for house-keeping tasks on the node itself. (Shelf A Shelf B)

Capabilities of controlling: 40 domains. 250 nodes in each domain.
