In Figure 1, the outmost frame stands for the system border, and dotted
line frames present board functions. The ZXMSG 5200 provides POTS and
xDSL access at the subscriber side and provides IP uplink at the network
side.
Narrowband services like POTS enter the TDM of ICS board for switching.
Voices are converted into IP packets through MPR’s voice compressing
functions. The packets are switched by the Ethernet switching chip and
sent to CNIC for network address conversion, and then switched again to
enter the IP network from the uplink interface.
xDSL services enter the Ethernet switching chip of ICS board and then is
sent to the IP network through the uplink interface.
