PlanningInstallation Manual 21Route IP Address 2 (GW_IP)*1Use the Route IP Address 2 field to record the IP address of the secondary (e.g., backup)gateway to be associated with each of the network units.For each unit, the unit's Gateway 2 is the one that will be accessed by the unit if Gateway 1 (i.e.,the primary Gateway) fails.The KX-TDA0480's gateway is typically a router or similar device. This address must conformto Internet Protocol addressing requirements, e.g. nnn.nnn.nnn.nnn, where nnn is a value of 0to 255 excluding 0.0.0.0 and 255.255.255.255.There is no default value.IP addressing information is usually supplied by a network administrator.Signal port no.Specification of TCP port number for call control (incoming calls)Setting range is from 0 to 60000. The default setting is 1720.2.2.3 Connection Information WorksheetIf the IP Gateway network’s internal DNS capabilities are to be used in the network, use theDNS Connection Information Worksheet to record summary information needed to configurethese facilities. The IP address and Destination Office Code information on this worksheet isalso used to configure Gatekeeper Inter-equipment Routing (TRS.DAT) information.A complete discussion of IP Gateway network DNS configuration is provided in Appendix A3of this document. See section 4.9.1 Configure Gateway Units (KX-TDA0480) forMaintenance Console Software procedures for configuring this information in the KX-TDA0480. A reproduction master for this worksheet is included in Appendix A8 of thisdocument.*1 See previous footnote.Connection Information WorksheetUnit Name and IPAddressSignalport no.TerminalCodeRemainingDigitsCommentsNY01 133.149.1.91 1720 215 2 Telephone extensionNY01 133.149.1.91 1720 217 2 G3 fax extensionNY01 133.149.1.91 1720 219 10 PSTN accessNY02 133.149.1.92 1720 215 3 Telephone extensionNY02 133.149.1.92 1720 217 3 G3 Fax extensionNY02 133.149.1.92 1720 219 10 PSTN accessNY02 133.149.1.92 1720 271 2 Telephone extensionvia PBXSF01 206.184.223.95 1720 516 1 Telephone extension
