This chapter offers information about installing your Cisco 633 symmetric digital subscriber line (SDSL) channel service unit/digital service unit (CSU/DSU) modem. If you are not familiar with the hardware or software parameters presented here, please consult your service provider (SP) for the values needed.
Table 2-1 lists the tasks to be completed when installing the Cisco 633.

Check the shipping carton carefully to ensure that the contents include the items you ordered. You can identify the Cisco 633 SDSL modem by the product name on the bottom of the front end of the modem (the end with the light-emitting diodes (LEDs)).
The contents of your carton may vary depending on your equipment provider. Table 2-2 shows a list of the standard contents of a Cisco 633 shipment.
| Contents | Description |
|---|---|
Cisco 633 | Cisco's SDSL modem for home/office use |
Cisco 633 SDSL CSU/DSU Modem Installation and Operation Guide (this publication) | Technical documentation for the Cisco 633 |
Cisco Broadband Operating System User Guide | Technical documentation for Cisco's Broadband Operating System used by the Cisco 633 |
Power supply | North American AC power adapter |
WALL/SDSL cable (Lavender) | RJ-11 telephone cable |
SERIAL cable (Blue) | 12-in-1 Smart Serial connector |
Your shipment might optionally contain a management cable (RJ-45-to-DB-9 serial cable, light blue in color). See Figure 2-1.

If any items you ordered were not delivered, please contact Cisco or your equipment provider. (For pin assignments of connectors used with your Cisco 633, refer to "Cisco 633 Connectors")
The hardware and software requirements necessary to install and configure the Cisco 633 include:
This section describes how to set up the hardware environment for your Cisco 633 SDSL modem.
To configure your Cisco 633, follow these steps:
Step 1 Connect the RJ-45 connector on the serial cable to the Cisco 633 management port. See Figure 2-2.

Step 2 Connect the other end of the serial cable to the computer serial port. (If your computer has only a DB-25 serial port, a DB--9-to-DB25 adapter is needed for connection.)
Step 3 Use the terminal access program from your PC's operating system to access the Cisco 633.
Step 4 Log in to CBOS as outlined in the "Log on to CBOS" section.
For the best access to the Cisco Operating System, use your terminal emulation program (such as HyperTerminal in Windows) to set your COM protocol to the following settings:
Figure 2-3 shows the cabling configuration for the Cisco 633 SDSL modem.

You can cable two Cisco 633s in a "back-to-back" configuration. This allows one Cisco 633 to terminate the traffic of a second Cisco 633 without Central Office (CO) equipment. See the following instructions for back-to-back cabling information:
Step 1 Plug one end of the SDSL cable into the WALL port on one of the Cisco 633 units.
Step 2 Plug the remaining end of the SDSL cable into the WALL port of the second Cisco 633 unit.
After you cable the Cisco 633s, you must configure them. See the "Configuration Procedures"for more information.
Step 1 Connect power to the Cisco 633 by plugging one end of the power supply into an appropriate electrical outlet and the other end into the power connector on the back of the unit.
Step 2 When you have powered up the Cisco 633, check that the Power LED is ON. If the Power LED does not illuminate, see "Troubleshooting," for more information.
You have now successfully installed the Cisco 633. See Chapter 3, "Configuration Procedures" for information on configuring the Cisco 633 for use.
