Description
• Leased Line: You can select a leased line.
Only if a Port Usage is selected.
Select the framing type for layer 1.
Possible values:
• CRC4 (Standard)
(default value)
• No CRC
The default value can be left in the majority of scenarios. You
can use the No CRC if required (e.g. in Sweden and France), if
the device is to be connected to a PABX.
Only if Port Usage = EURO ISDN S2m (TE) or EURO ISDN
S2m (NT)Enter the call number for the connection.
Only if Port Usage = EURO ISDN S2m (TE)
To ensure compatibility with special service providers, a further
option is provided for Port Usage = Euro ISDN S2m (TE): If
you set the switch type appropriately, you can select a value for
the variable Channel Selection. This defines how the B chan-
nel is selected for an outgoing call.
Possible values:
• Any Channel (default value): The device tells the PABX that
all channels are available. The exchange of the PABX selects
the channel to be used.
• No channel identification
: The device sends no IE (Information Element) for channel
identification. The exchange selects the channel to be used.
• Submit preferred channel
: The device selects the channel to be used and signals this to
the exchange.
You can normally use the default value. It is only necessary to
change the setting in a few special cases.
