9.2.8 Application scenario

Transmitting handshake signals and data services
The DTE is connected to the 8RS232H card of the local RC3000-15, which transmits services
to the remote RC3000-15. As a DTE, the RS232H card of the remote RC3000-15 controls the
remote DCEs.

Figure 9-1 Handshaking signals and data services

Data collinear service
The 8RS232H card supports data collinear function. After this function is configured, data
transmitted by any node of multiple nodes can be concurrently received by other nodes. In
this case, start or bus topology can be used for networking.

The RC3000-15 devices of multiple users are connected to the CO RC3000-15. After the CO
RC3000-15 is configured with data collinear function, data sent by a user can be concurrently
received by other users.
SW1 Function
Reserved
SW1 is in all OFF status after delivery, so it can work properly.
When KEY1 is in ON status, the card waits for upgrade and all service operations
are stopped.
When the RS232H interface type is configured to automatic mode, you must use the
cable provided by Raisecom or make the cable as specified in the appendix; otherwise,
the correct interface type (DCE or DTE) cannot be identified.
When interface handshake signals are disabled, the terminal-mode and handshake-info-
reference do not take effect.
