Nortel recommends CDP because it requires the least dialing manipulationbetween the SRG50 and the main office call server. The dialing plan choice also determineswhether the DN on the SRG50 matches the BUID (CS 1000) or DN (CS 2000) on the main office.Dialing plans between the SRG50 and the main office call server must be compatible. Privatedialing plan configuration is described in detail in the BCM50 Networking Configuration Guide(N0027156).The type of dialing plan, CDP or UDP, is determined by the main office configuration.The path to the SRG50 Element Manager panel for setting up the dialing plan is Configuration >Telephony > Dialing Plan > Private Network > Dialing Plan - Private Network panel >Private Network Settings subpanel (Figure 15).SRG50 net mask Configured as part of BCM50 foundation configuration.Path: Configuration > System > IP Subsystem > IP Subsystempanel > General Settings tab > IP Settings details subpanelIP address ofSRG50 gatewayConfigured as part of BCM50 foundation configuration.Path: Configuration > System > IP Subsystem > IP Subsystempanel > General Settings tab > IP Settings details subpanelVLAN If the SRG50 operates as part of a VLAN, obtain the requiredidentifiers from the VLAN administrator.Configuration > Data Services > DHCP Server > DHCPServerpanel > IP Terminal DHCP Options tab > VLAN IdentifierssubpanelPSTN number fordialing into themain office fromthe SRG50 whenin local modeRequired to specify a PSTN fallback route.
