5. Configuring SMDS

The Switched Multimegabit Data Service (SMDS) is a wide-area networking service offered by some Regional Bell Operating Companies (RBOCs) and by MCI. This chapter describes the configuration tasks for the SMDS packet-switched software.

For a complete description of the commands mentioned in this chapter, see Chapter 6, “SMDS Commands.” You can search online at to find documentation of related commands.

SMDS Hardware Requirements

You need the following hardware, equipment, and special software to configure SMDS:

  • CSC-MCI or CSC-SCI serial interface controller card, or an HSSI interface on chassis-based systems, or the serial port on an IGS router.

    To operate on CSC-SCI or CSC-MCI cards, SMDS requires that the appropriate microcode version be installed. Version numbers are 1.2 (or later) for CSC-SCI and 1.7 (or later) for CSC-MCI.

  • EIA/TIA-449 or V.35 applique on chassis-based systems, or EIA/TIA-449 transition cable on an IGS router.

  • SMDS data service unit (SDSU) device.

  • Packet-switched software option with the system software.

Figure 5-1 illustrates the connections between the different components.
