2.3.2 100 Mbit/s downlink interface card
There are 5 slots for the downlink interface card. A single slot contains 4 interfaces, in which
Slot 6 supports the GPS card and Slot 7 supports serial card. The rate of the downlink
interface is 100 Mbit/s. According to the service type, the interface cards can be divided into
100 Mbit/s RJ45 interface card, 100 Mbit/s SFP interface card, 100 Mbit/s 1×9 SC/PC
interface card, and 100 Mbit/s 1×9 ST/PC interface card.
100 Mbit/s RJ45 interface card
The 100 Mbit/s RJ45 interface card provides 4 electrical interfaces. It can be inserted into Slot
3 to Slot 7. The card supports 0.5U subcard in the upper and lower parts. Figure 2-5 shows the
100 Mbit/s RJ45 interface card.
