This is Control card of the zte bts. This is the CPU of the system. It contains the software for the complete bts. Whenever the alarm software runs abnormally occurs then you need to upload mo file in this card. It has one ETH0 port which is connected to the media cable of the network. Debug port of this card is used for configuration of the BTS.

This card has six optical module. In these optical module SFP of rating 1.25 G or 2.67 G are used for connection with RSU60 or RSU82. This connection is provided by optical patch cord cables. Sometimes these cables are damaged and alarm of RRU Link broken is generated.
