Below is a detailed description of the meaning of each field:
Layer-list In the layer list, you can freely define the different B-channel protocols by combining
various ISDN layers. This enables compatibility to devices from other manufacturers that
use different B-channel protocols to be set.
The following table below is provided as an example and also shows the default settings
for an
ELSA LANCOM Business:
Below is a detailed description of the meaning of each field:
Device-name In the device name column, you can enter a remote device name from
the name list. If one line in the Round Robin list is insufficient for all
desired call numbers, the line can be extended as shown below: The #
character and a unique index are added to the device name (e.g. GLAS-
GOW#1) and it is entered on the next line.
Round-Robin The DDI numbers of all possible remote stations are entered here under
their corresponding device names. The individual DDI numbers must be
separated by hyphens.
Head In the Head column, the following entries are possible:
Last : The next connection to be established will begin with the DDI that
was successfully used for establishing the last connection (default).
First : The next connection to be established will always begin with the
first DDI.
For a logical remote station, this field can be modified only by means of
its
first entry in the table. The field is automatically updated when
other entries are made for this remote station.

WAN-layer In this column, you can enter an original name designating the layer combination that
you use. These names can then be used in the name list 'layer name' column depend-
ing on their spelling to set the protocol.
If an entry with the name
DEFAULT is defined in this column, the settings stored
there are always used when no layer name can be assigned (e.g. a caller does not
transmit his or her call number). This entry is also used when a group 0 leased-line
connection is established. If the
DEFAULT entry is not present, a B channel protocol
developed by ELSA is used as the default. The user may delete or change any of the
layers predefined here.
Encaps. Additional information regarding the data to be transmitted may be specified in the
Encaps column. The following entries are possible:
ETHER The data is provided with an Ethernet header. This setting is required
for communication with older
ELSA LANCOM devices.
TRANS No Ethernet header is sent in this setting. Only “pure“ IP data packets
are transferred, for example. This setting provides the greatest possi-
ble effective data throughput.
