Data Sheet
7.2.5.1 FAinfA_1fr
W66910 PCI ISDN S/T-Controller
This test checks if TE does not lose frame alignment on receipt of one bad frame. The pattern for the bad frame is defined as
IX_96 kHz. This pattern consists of alternating pulses at 96 kHz during the whole frame.
Device

Settings
None
Result
Pass
7.2.5.2 FAinfB_1fr
This test checks if TE does not lose frame alignment on receipt of one IX_I4noflag frame which has no framing and balancing
bit.
Device
W66910
Settings
None
Result
Pass
7.2.5.3 FAinfD_1fr
This test checks if TE does not lose frame alignment on receipt of one IX-I4viol16 frame. The IX_I4viol16 frame remains at
binary "1" until the first B2 bit which is bit position 16. The pulse sequences are: Framing bit, balancing bit, B2 bit, M bit, S bit,
balancing bit. The TE should reflect the received F_A bit (F_A="1") in the transmitted frame.

7.2.5.4 FAinfA_kfr
This is to test the number k of IX_96 kHz frames necessary for loss of frame alignment.
Device
W66910
Settings
k =2
Result
Pass
7.2.5.5 FAinfB_kfr
This is to test the number k of IX_I4noflag frames necessary for loss of frame alignment.
