3.3.3 Connecting the T1/E1 Cable
TGWxE1-2G offers an RJ45 jack as the T1/E1 connector for making ISDN connection with the Aeonix.
Please identify the connector type and interface impedance of the other side equipment before making the
T1/E1 connection.
If the other side equipment offers the same RJ45 jack, use CAT5 cable with RJ45 plugs on both side to
make the T1/E1 cable connection. Be sure to match TX and RX pair according to the PIN specification
when making the CAT5 cable.
If the other side equipment offers separate TX/RX coax connectors for the T1/E1connection, use
RJ45-Balun-Coax cable sets, as depicted in the following figure.
Figure 3-4 Connecting the T1/E1Cable
The T1/E1 ports are numbered 1 to 4 from left to right. If the hardware configuration is 1
T1/E1, insert one end of the T1/E1 cable to the leftmost T1/E1 port on the TGWxE1-2G.
3.3.4 Connecting the Grounding Cable
When installing in an equipment room facility providing independent grounding, it is required to connect
the chassis ground tab on the TGWxE1-2G with the protective grounding system in this environment.
Proper grounding not only provides a guarantee for safe operation of the equipment but also enhances the
capacity of the equipment to resist disturbance and ensures the quality of voice communication.
The TGWxE1-2G series main chassis and expansion chassis are equipped with a M4 grounding screw
with a mark in their backs. Please use the M4 screw to connect the grounding wire.
