Modem Unit
The Modem Unit (MODU) provides an asynchronous modem for access to the system database
and remote maintenance. This module is optionally installed on the BKSU’s MBU and includes
a 9600 baud modem. The modem may be accessed from any station or CO. The modem is
installed in the lower right of the BKSU. Refer to
Figure 3-12: MODU Installation Location .
Installing the MODU
1. Using a grounding strap, unpack the MODU from its antistatic bag in the packing box.
2. Locate the MODU connector on the MBU.
3. Locate the CN1 connector on the MODU.
4. Position the MODU so the CN1 matches with CN13 on the MBU.
5. Push the MODU onto its connector, making sure it is properly seated.

The modem may not always connect at 9600 bps. If you encounter a situation where
you cannot connect at 9600 bps, change your computer’s baud rate to 4800 bps.
