The physical boards of the GEHUB and GEPUG are the same. After being loaded with different software, the physical boards perform different functions. These boards have the same ports. Of the six ports, four ports are labeled E1/T1, one 2MO, and one 2M1.
Table 1 describes the ports on the GEHUB/GEPUG panel.

E1/T1 (24-31) |
E1/T1 port, used to transmit and receive the E1/T1 signals on routes 24-31 |
DB44 |
2M0 |
One of the two clock signal output ports, used to extract the 2 MHz line clock signals from the upper-level devices, send them to the GGCU, and take them as the system clock source. |
