Menu 1 – General Setup.

17. RAS S/W

18. Ethernet

19. LAN Packet

Which Triggered

Last Call

Shows the first 48 octets of the LAN packet that triggered the last outgoing call.

There are three different types of packets: IP, IPX, and RAW. By viewing the

packet information, you can determine which station sends a packet to trigger an

outgoing call.

Figure 13-3 shows two examples of triggering packets from the LAN: the first of an ICMP ping

packet (Type: IP) and the second a SAP broadcast packet (Type: Raw). With this information,

you can determine the workstation from the source IP address or the source MAC address of the

packet.
