The physical boards of the GEIUA, GEIUB, GEIUP, and GEIUT are the same. After being loaded with different software, the physical boards perform different functions. These boards have the same ports. Of the seven ports, four ports are labeled E1/T1, one 2MO, one 2M1, and one TESTOUT.
Table 1 describes the ports on the GEIUA/GEIUB/GEIUP/GEIUT panel.
Port |
Function |

|---|---|---|
E1/T1 (0-7) |
E1/T1 port, used to transmit and receive the E1/T1 signals on routes 0-7 |
DB44 |
E1/T1 (8-15) |
E1/T1 port, used to transmit and receive the E1/T1 signals on routes 8-15 |
DB44 |
E1/T1 (16-23) |
E1/T1 port, used to transmit and receive the E1/T1 signals on routes 16-23 |
DB44 |
E1/T1 (24-31) |
E1/T1 port, used to transmit and receive the E1/T1 signals on routes 24-31 |
DB44 |
2M0 and 2M1 |
Output ports for the 2.048 MHz clock signals, used to export the extracted line clock for system reference |

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