Am186™CC Voice Over Ethernet CodeKit Software
V1.0 – September 1999
1.4 Setting Up the Build Environment
Before the CodeKit software is built, you must set up the build environment. To do this, run the ENVIRON. BAT
command file. Running the command file sets up the environment variables listed in the table below.
This batch file assumes that the tools have been installed in their default locations on the C: drive.

1.5 Setting Up the Target Hardware
This section describes how to set up the target hardware using either an Am186CC microcontroller CDP and daughter
module or an Am186CC microcontroller ISDN-to-Ethernet router reference design board.
1.5.1 General Setup
You need to connect a touch tone phone to the POTS 1 connection on either the CDP daughter module or router
board. You also need to connect an RJ-45 cable, for the Ethernet connector on your board, to a 10Base-T network
or hub.
1.5.2 Revision 2.0 or 2.1 CDP and Revision 2.1 Daughter Module
• DIP switch bank SW12: Ensure DIP switch 4 is on.
• DIP switch bank SW10: All DIP switches should be off.
• DIP switch bank SW8: All DIP switches should be off.
• DIP switch bank SW9: Ensure DIP switch 4 (HDLC_D EN) is set to disabled.
This software requires that HDLC D from the Am186CC microcontroller must be able to transmit directly to the
Am79C031 DSLAC™ device on the daughter module. To do this, populate/depopulate the following resistors on the
bottom of the daughter module. For this CodeKit, use the HDLC D column settings listed in the table below:
