8.1.2 Permanent circuit

to any subscriber, ISDN also supports the use of permanent
circuits switched to a specific remote location.
These permanent circuits are available after setting up
Layer 1, in other words after synchronizing both terminals by
exchanging HDLC-frames.
As a quick test of a permanent circuit, you can simply call
the opposite end using a selected B-channel.
However, for a more revealing test of a permanent circuit,
you should perform a bit error rate test.
Both ends of the permanent circuit must use the same
channel.
