Huawei RTN 980L Board SL91SP3S Overview

The SP3S is a 16xE1 75-ohm/120-ohm tributary board

The SP3S has two functional versions: SL91SP3S VER.B and SL91SP3S VER.C. The SP3D also has two functional versions: TNH1SP3D VER.B and TNH1SP3D VER.C. The difference between VER.B and VER.C is that path indication on the front panel is optimized and the board power consumption is reduced.

SP3S/SP3D boards receive and transmit E1 services on OptiX RTN 980L that transmit E1 services in Native mode. The E1 services come from UEs or TDM networks.

An SP3S receives and transmits 16 channels of E1 signals. An SP3D receives and transmits 32 channels of E1 signals.

There are indicators and E1 ports on the front panel of the SP3S/SP3D.

The SP3S/SP3D board can be inserted in Slots 1 to 14, which have consistent logical slot numbers on the NMS.

The port impedance of the SP3S/SP3D can be identified by the board feature code of the bar code. A board feature code refers to the number next to the board name in a bar code.

This section describes the technical specifications of the SP3S/SP3D, including E1 port specifications, mechanical specifications, and power consumption.
