Working Principle

21

Working Principlel Narrowband service

After entering the TDM switch of the GIS, suchnarrowband service as POTS transfers voice intoIP packet by the voice compression function of theMPRB. The service switches to the CNIC throughan Ethernet switching chip for Network AddressTranslation (NAT), and then enters the IP networkfrom the uplink interface by Ethernet switching.

l Broadband service

Direct forward to Ethernet switching and uplink tometro Ethernet network
