The Metro1000 SS42SP1S/SS42SP1D/SS42SP2D/SS44PD2S/SS44PD2D/SS44PD2T single boards have interfaces and bar codes on the faceplate.
The faceplate of the Metro1000 SS42SP1S/SS42SP1D/SS42SP2D/SS44PD2S/SS44PD2D/SS44PD2T single board is shown in Figure 1.
The Metro1000 SS42SP1S/SS42SP1D/SS42SP2D/SS44PD2S/SS44PD2D/SS44PD2T boards have the E1 electrical connector on the panel, which is a 2mmHM type connector (4 x 6pin), and the number on the connector indicates the serial number of the interface.
The Metro1000 SS42SP1S/SS42SP1D/SS42SP2D/SS44PD2S/SS44PD2D/SS44PD2T boards realize the receiving and transmitting of the E1 electrical signals, and complete the processing of the VC-12 channel overheads as well as the generating of the various alarm signals on the branch.
SP1S is a 4-channel E1 electrical interface board, SP1D is an 8-channel E1 electrical interface board, SP2D is a 16-channel E1 electrical interface board, PD2S is a 16-channel E1 electrical interface board, PD2D is a 32-channel E1 electrical interface board, and PD2T is a 48-channel E1 electrical interface board.
The functions and characteristics of the SP1S/SP1D/SP2D/PD2S/PD2D/PD2T single boards are shown in Table 1.
The maximum power consumption of the SP1S single board at room temperature (25°C) is 3.95W.
The maximum power consumption of the SP2D single board at room temperature (25°C) is 5W.
The maximum power consumption of the PD2D single board is 14.5W at room temperature (25°C).
