Serial interface related information

The SmartNode 2300 supports the V.35 and X.21 standard for synchronous serial interfaces with speeds up to
2 Mbps. Devices that communicate over a serial interface are divided into two classes:
• Data terminal equipment (DTE)—The device at the user end of the user-to-network interface. The DTE
connects to a data network via data DCE, and typically uses clocking signals generated by the DCE.
• Data communications equipment (DCE)—The device at the network end of the user-to-network interface.
The DCE provides a physical connection to the network, forwards traffic, and provides a clocking signal
used to synchronize data transmission between DCE and DTE devices.
The most important difference between these types of devices is that the DCE device supplies the clock signal
that paces the communications on the interface.
Note
The SmartNode 2300 is working as a DTE per default.
Before you connect a device to the synchronous serial port, labeled SERIAL 0/0 on SmartNode 2300, you
need to check the following:
• Confirm that the device you are connecting to is a DCE providing a clock signal on the synchronous serial
interface.
• Type of connector, male or female, required connecting at the device
• Signaling protocol required by the device must be X.21 or V.35

QoS related information

Check with your access service provider if there are any QoS related requirements, which you need to know
prior to configuring SmartWare QoS management. Check the following with your access service provider:
• What is the dedicated bandwidth, which you have agreed with your access service provider?
• How does your provider perform packet classification, e.g. which ToS bits have to be used to define the sup-
ported classes of service?
Configuring Ethernet and serial ports
In SmartWare Ethernet and serial ports represent the physical connectors on the SmartNode hardware. Since
ports are closely-knit with the physical structure of a SmartNode, they cannot be created but have to be config-
ured. The configuration of a port includes parameters for the physical and data link layer such as framing and
encapsulation formats or media access control. Before any higher-layer user data can flow through a physical port,
you must associate that port with an interface within the IP context. This association is referred to as a binding.
For information and examples on how to configure an Ethernet port refer to chapter 12,
uration" on page 127 or for a serial port to chapter 14,
Creating and configuring IP interfaces
Today SmartWare supports one instance of the IP context, named "router". The number and names of IP
interfaces depend upon your application scenario. In SmartWare, an interface is a logical construct that pro-
