connections, yet the provision of a D channel is generally billed, fixed connections
without a D channel offer the best value for money.
If one channel is sufficient in the long term, select D64S. If the data throughput of a
single channel is not satisfactory, consider the deployment of the D64S2. Two D64S
connections may be used for connections to two different remote stations. This
combination is also referred to as D64SY:
All three types are set as Group 0 fixed connections in the interface table. The versions
are distinguished by the YV. flag in the interface table, the layer-2 options in the layer list
and the entries in the channel list.
Setting up fixed connections
The following settings are required to prepare the router for use with the various fixed
connection types.

the layer used.
For connections with two B channels to a single remote station, enter bundle as
well as compr. as required.
When connecting to two remote stations via 2 B channels, compr. can be specified.
Settings in the channel list
Use the channel list to specify the channels to be used for the fixed connection. The
same settings must be used for the channels and their sequence on both sides of the
connection. If applicable, the number of channels to be used for a backup connection
should be entered here (also the same on both sides of the connection).
