iii. The CNIC sub-card on the ICS distributes received RTP packets.
When the system is receiving RTP packets, the sub-card distributes
the RTP packets to the corresponding MPR boards according to the
packet RTP number. This is implemented by changing the
destination address of the RTP packet into the destination IP
address in the system.
iv. The ICS board works with dual CPUs. The master CPU implements
call processing, H.248 protocol processing, Ethernet layer-2
protocol processing, TDM network and Ethernet switching network
controls. The slave CPU scans narrowband line cards and
subscribers in the local shelf. It communicates with the master CPU
by means of HDLC through the 2MHW timeslots.
