Section 7—TAC Access to Coprocessor
7.1 Overview
TAC support for
coprocessor
problems
The Technical Assistance Center (TAC) has the capability of providing
assistance with troubleshooting coprocessor related problems.
Troubleshooting some problems may require direct access to the
coprocessor. A telephone communications link must be connected to the
coprocessor to allow direct access from TAC.
The diagram right illustrates this communications link.

Overview of
activities to enable
TAC access
There are several distinct tasks required to establish the TAC
communications link to the coprocessor.
• Configure the modem options using switches and internal registers.
• Connect the modem to the WSI2 I/O board.
• Connect the modem to a switched (dialable) telephone line.
• The coprocessor software defaults to the proper configuration of Serial
Port 1 and no coprocessor configuration actions are required.
• Apply power to the modem.
• Establish the telephone connection with TAC under direction of the
TAC engineer.
