• Power Patch Panel
The powered patch panel has two RJ-45 connectors per IP Terminal. One port connects to the
switch and the other port connects to the IP Terminal. The patch panel contains an integral power
supply, adding power to the spare pairs of the RJ-45.
When the IP Terminal is connected to the powered patch panel, the telephone automatically
receives power via the spare pairs on the CAT 5 cable. A local power adapter is not needed.
• Power over Ethernet (PoE)
IP Terminal (IP4WW-24TIXH-C) supports 802.3af standard for PoE.
PoE (Power Over Ethernet) is a LAN technology that allows standard 10Base-T/100Base-TX data
cables to pass electrical current from a power source to a requesting end device.
NAPT
This function is used to establish SIP communication with the main device and RTP communication
among SIP Terminals through the NAT on an IP network.
• NAT Traversal
The NAPT (Network Address Port Translation) feature gives the SL1100 the ability to “traverse” its
own subnet. With NAPT used in the SL1100, the network administrator can place the CPU and the
VoIPDB in the customers LAN while still making it accessible to users outside the local LAN.
• Static NAT
This method is used to convert an address (a WAN-side address for the NAT router) previously
specified in the terminal configuration. For this method, a conversion table is statically set up for the
NAT router, and then a packet for a specific port is transferred to a specific terminal by using the
port forwarding function of the NAT router.
• Dynamic NAT
This method is used to automatically acquire the WAN-side global address for the NAT router and
convert it.
NAT Traversal
Besides ordinary NAPT feature SL1100 supports NAT Traversal which does not require Port
Forwarding setting at remote side router. This feature is effective when PRG 15-05-45 is set "1" (On).
Example of NAT Traversal network and necessary settings for System and IP Terminal are shown in
below

page 1-425
and
