PlanningInstallation Manual 39Signalling Port (CALL_PORT)Use the Signalling Port field to record the port on which transmission will be initiated.In the sample, the unit is configured to the default value, 1720. This value affects one port only.H.245 Start Port (H.245_PORT)Use the H.245 Start Port field to record the port on which H.245 signalling will be initiated.In the sample, the unit is configured to the default value, 1721.This value affects the four ports. The designated port and the next three ports in sequence (e.g.,1721, 1722, 1723, and 1724).RTP Start Port (RTP_PORT)Use the RTP Start Port field to record the port on which RTP signalling will be initiated.In the sample, the unit is configured to the default value, 5004.This value affects eight ports. The designated port and the next seven ports in sequence. Evenports are RTP (e.g., 5004, 5006, 5008, and 5010). Odd ports are RTCP (e.g., 5005, 5007, 5009,and 5011).Connect Time (NOCTIME)Use the Connect Time field to record the time allowed for a connection to be established.This parameter defines the time frame during which the KX-TDA0480 will try to establish thecall. If a call is not established within this time (e.g., the called KX-TDA0480 is notresponding) a fast Busy Tone is returned. When implementing KX-TDA0480 in a dialup WANscenario -WAN connection setup time must be included as a timing consideration.The range of acceptable values includes from 1 to 99 seconds.In the sample, the unit is configured to the default value, 30 seconds.UDP Port No. for Supplementary Service (ISDN_ANF_PORT)A port used to transfer QSIG signals in an IP network when they are received, using the QSIGconnectionless supplementary service. The default value of this port is 5003. When using thistype of port, it will be necessary to unify it within the network.DNS Setup, SNMP Setup, Gatekeeper, and Notify E-MailRefer to Section 2.2.4 Common Configuration Worksheet.
