E3/T3 Cable
Description
An E3/T3 cable connects a 1E3/CE3/T3/CT3 interface card to a remote device. The cable connects to the interface card through the SMB75 connector and connects to the remote device through the BNC connector.
Each 1E3/CE3/T3/CT3 interface card needs to be connected to a remote device using two E3/T3 cables.
Structure and Pin Assignments
Figure 8-26 shows the structure of an E3/T3 cable.
Table 8-40 lists the pin assignments of an E3/T3 cable.
Connection
- Connect the SMB75 connector of one E3/T3 cable to the Tx interface on the 1E3/CE3/T3/CT3 interface card, and the BNC connector to the Rx interface on the remote device.
- Connect the SMB75 connector of one E3/T3 cable to the Rx interface on the 1E3/CE3/T3/CT3 interface card, and the BNC connector to the Tx interface on the remote device.
Ordering Information
If the two devices to be connected are far from each other, you can use trunk cables to extend the E3/T3 cables. In this case, you also need to use a coaxial connector for each E3/T3 cable.
Table 8-41 provides the E3/T3 cable ordering information.
