GENERAL INFORMATION

CHAPTER 1 - GENERAL INFORMATION

1•1 INTRODUCTION

This manual provides general information, preparation for use and installation instructions, operating

instructions, functional description, and support information for the MPC8260TCOM board.

1•2 FEATURES

The main features of the MPC8260TCOM board are as follows:

• Two Fast Ethernet channels connected guilelessly to the Level One LXT970 device.

• The 2 Fast-Ethernet use FCC1 and FCC3.

• Each one of the Fast - Ethernet module can be disable/disable and controlled by SW.

• Two DS3 channels using the TRAN-SWITCH TXC-03401 FRAMER and TRAN-SWITCH TXC-

20153G DS3 Line Interface Module.

• Each one of the DS3 framer controlled via the MPC8260.

• The 2XDS3 use the TDMA1(DS3_1 FCC2) and TDMA2 (DS3_2 FCC3).

• Each one of the DS3 module can be disable/enable by HW.

• Eight T1 interfaces using MCC1 and MCC2.

GENERAL INFORMATION

1•4 GENERAL DESCRIPTION

The MPC8260TCOM Board includes the following modules: 8 x T1/E1, 2 x Fast Ethernet, 2 x DS3.

The MPC8260ADS includes the following modules: ATM155 and Fast Ethernet.

Both MPC8260TCOM and MPC8260ADS implements the following network for H/W & S/W development

applications:

ATM155M (FCC1 on MPC8260ADS) + 8 x T1 (MCC1 & MCC2),

ATM155M (FCC1 on MPC8260ADS) + 2 x Fast Ethernet (FCC2 on MPC8260ADS, FCC3),

ATM155M (FCC1 on MPC8260ADS) + 2 x DS3 (TDMa1 to FCC2, TDMa2 to FCC3),

3 x Fast Ethernet (FCC2 on MPC8260ADS, FCC1, FCC3).

NOTE: Some modules share the same GPIO. Care must be taken when configuring each one of the

modules, to prevent a conflict between them. Before operating the board the user should define the modes

of operation and configure the MPC8260 GPIO to the corresponding module.

Special care must be taken when using the Fast Ethernet interfaces. It do not have a h/w enable

signal, it is configured only through the MII MDC,MDIO signals.

SOFTWARE AND HARDWARE PREPARATION

CHAPTER 2 - SOFTWARE AND HARDWARE PREPARATION

2•1 SOFTWARE PREPARATION

The TCOM is not a stand alone board. It should be connected to the MPC8260ADS. To select the desired

configuration and ensure proper operation of the MPC8260TCOM board, changes in the MPC8260 GPIO

configuration may be required. The following table describes the different configurations of all the modules

on the board. NOTE:

The FE modules have no H/W protection. Before using one of the FE module make sure that other modules

using the same GPIO are disabled. The following table shows the various types of communication

channels that can be implemented by connecting the TCOM & ADS cards.

The I/O are related to the MPC8260.

The dark column are the modules on the ADS.
