GE 800 7. Configuration of IP-Terminals
1.1/1209 41
*Note: The setting is saved in the ET 901 (min. firmware version 2.2) or in the ET 908 and is not
saved in the Intercom Server configuration – it can be entered for information purposes only!
In the column Host Name a name for the IP-subscribers can be entered which identifies the IP-sub-
scriber for the DHCP server. If no name is entered, a standard name will be used (when using DHCP).
In the column Version the firmware version of the IP-station / IP-box is indicated.
In the column StationType the station type (connected to the ET 901) is indicated.
In the column
EB-Interface
connected expansion/option boards are indicated.
In the column Password it is possible to advise a password for the individual subscribers, see
”Passwords for subscribers” on page 42.
Speed/Duplex:
In the combo-boxes Uplink and Downlink the ethernet operation mode of the network link (RJ 45)
can be selected:
Autonegotiation (Standard)
10MBit / half duplex
10MBit / full duplex
100MBit / half duplex
100MBit / full duplex
VLAN:
In the following columns the so called “frame tagging” (IEEE 802.1Q) can be configured – this also
means that the Ethernet header is extended by 4 bytes:
In the column Pri the priority level can be set (IEEE 802.1P), i.e. a total of 8 priority levels from 0 to 7.
The priority for the transmission of voice/speech shall be set to level “6”.
In the column CFI the bit for the “Canonical Format Indicator” can be set (i.e. 0 or 1).
In standard, the CFI bit shall always be set to “0”.
In the column VID the VLAN-ID is set (IEEE 802.1Q), i.e. in total 4096 (2
12
) from 0 to 4095 VLAN-IDs
are possible, but “0” and “4095” are reserved.
Sending the configuration
It is possible to send either the entire configuration, only the configuration of IP-subscribers that have
been modified or the configuration of the subscribers selected in the table.
Open the drop-down-list next to the button Write Settings: and select
all: to send the entire configuration
modified: to send the configuration only to subscribers where settings have been modified
selected: to send the configuration only to subscribers selected in the table
Click on Write settings to send the configuration to the selected IP-subscribers. An acknowledgement
window appears before sending. Click on “Yes” to send the configuration.
Attention:
In standard, switches do not accept “tagged” Ethernet frames from terminal equipment (e.g. PCs,
Intercom stations)!
Therefore when using VLAN, an appropriate configuration of the respective switch is required!
Attention:
If an IP-address, which already exists in the network, is advised to a subscriber, heavy malfunctioning of the
network may occur. Therefore it is recommended to always receive the current configuration of the system in
order to avoid IP-address collisions in the network.
