1.4 Lan Interface Accommodation
There are four LAN ports on the front panel of Telephony Server, of which LAN1 and LAN2 play a central role
in managing the whole system. This section explains usage of them (LAN1/LAN2). Additional information
about the LAN ports is described in "Management by 4-LAN Port" of the Installation Manual.
1.4.1 LAN1 Accommodation
LAN1 mainly accommodates the devices/terminals for call controlling. They do not need to keep links with Te-
lephony Server when system changeover is performed in dual configuration system. In each case where the sys-
tem is in single configuration or dual configuration, IP address (ACT) is basically assigned to the devices/
terminals as Telephony Server address.
When the system is in dual configuration, IP address (System #0/#1) is used instead of IP address (ACT)
Note:
in the following cases.
• Telephony Server address as FTP server
• Telephony Server address as registration destination for IP devices accommodated in SP-PHI and us-
ing SIP mode. (See
