Functional Description
2.5.6
Activation/Deactivation
An incorporated finite state machine controls ISDN layer-1 activation/deactivation according to
CCITT (see chapter 3.4).
Loss of Synchronization / Resynchronization (TE mode)
The following section describes the behaviour of the PEB 2085/86 in respect to the CTS test
procedures for frame alignment.
Setting of the ISAC-S
The ISAC-S needs to be programmed for multiframe operation with the Q-bits set to "1".
STAR2: MULT = 0
SQXR:SQX1-4 = 1111B (xF)
2.5.6.1 FAinfA_1fr
This test checks if no loss of frame alignment occurs upon a receipt of one bad frame. The
pattern for the bad frame is defined as IX_96 kHz. This pattern was revised so that a code
violation is generated at the begin of the next info 4 frame.
