The PE3S/PE3D/PE3T/PT3S/PT3D/PT3T single boards have single board indicators, interfaces, and barcodes on the faceplate.
The panel of the PE3S/PE3D/PE3T/PT3S/PT3D/PT3T single board is shown in Figure 1.
The E3/T3 electrical interface of the PE3S/PE3D/PE3T/PT3S/PT3D/PT3T single board is on the panel and is an SMB type coaxial connector, the number on the connector indicates the serial number of the interface, Tx indicates the transmitter side and Rx indicates the receiver side.
The PE3S/PE3D/PE3T/PT3S/PT3D/PT3T single board realizes the receiving and transmitting of the E3/T3 electrical signals, and completes the processing of the overhead of the VC-3 channel as well as the generating of the respective alarm signals on the branch.
The functions and characteristics of the PE3S/PE3D/PE3T/PT3S/PT3D/PT3T single board are shown in Table 1.
