This describes the panel of the optical interface boards. The GOIUA, GOIUB, GOIUP, and GOIUT use the same physical board but perform different logical functions by loading different software. These boards have the same ports. Of the four ports, one port is labeled RX/TX, one 2MO, one 2M1, and one TESTOUT.
Table 1 describes the ports on the GOIUA/GOIUB/GOIUP/GOIUT panel.

2M0 and 2M1 |
Output ports for the 2.048 MHz clock reference, used to export the extracted line clock and take it as the reference clock for the system |

TESTOUT |
You can modify the register value to obtain different test clock signals. By default, the 2.048 MHz clock signals are generated from this port and taken as the system test clock. |
