14.17 Leased Line on an ISDN Access
Besides dial-up connections to any subscriber, ISDN also supports the use of permanent
circuits switched to a specific remote location (leased lines). These leased lines are
available after setting up Layer 1, in other words after synchronizing both terminals by
exchanging HDLC-frames. The location where the clock is generated can be selected
(page 246). A quick and simple test of a leased line can be made by placing or taking a call
on a selected B-channel. However, for a more precise test, a bit error rate test should be
run.
Both ends of the leased line must use the same channel.
