3. Two IP Addressing Groups:The two diagrams show the data VCs and voice VCsthrough the same DSLAM.a) To distinguish the two groups, use one set of IPaddresses, with a range of 10.0.20.1 to 10.0.20.63(/26 subnet) for the data VCs.b) Use another set of IP addresses with a range of10.0.21.1 to 10.0.21.63 (/26 subnet) for the voiceVCs.4. Default Router and Voice Gateway:a) Assign the 10.0.20.1 address to the default routeron the data subnet.b) Assign the 10.0.21.1 address to the voice gatewayon the voice subnet.5. IP Addresses and Subnet Masks on WAN Ports:a) Assign the 10.0.20.0 address with a subnet mask of255.255.255.192 (or /26) to the data VC on theWAN port.b) Assign the 10.0.21.0 address with a subnet mask of255.255.255.192 (or /26) to the voice VC on theWAN port.The two WAN VCs themselves, though, do not have IPaddresses. In the data group, only the hosts and thedefault router have IP addresses. In the voice group,only the IADs and the voice gateway have IP addresses.HDIA Data Group (10.0.20.0)4Hosts1HostIADIADIP Addr: 10.0.20.2Net mask: (/32)PII: 1.4.13VC: 528IP Addr: 10.0.20.4Net mask: (/30)PII: 1.4.14VC: 528HDIADSLAMIP Addr: 10.0.20.0Net mask: (/26)PII: 1.2.1.20IP Addr: 10.0.20.1DefaultRouterHDIA Voice Group (10.0.21.0)8Phones8PhonesIADIADIP Addr: 10.0.21.2Net mask: (/32)PII: 1.4.13VC: 22IP Addr: 10.0.21.3Net mask: (/32)PII: 1.4.14VC: 22HDIADSLAMIP Addr: 10.0.21.0Net mask: (/26)PII: 1.2.1.21IP Addr: 10.0.21.1VoiceGatewayHDIA Netmodel—Data and Voice Groups with Netmasks&RSSHU(GJH,QVWDOODWLRQDQG2SHUDWLQJ*XLGH
