VT-5. C-Bit Decoding
In the presence of a receive SONET/SDH bit error rate, the device may destuff the DS1 from the VT1.5 incorrectly.
This is the result of an error in the VT1.5 C-bit decoding process. The C-bit decoding process should be capable of
correcting single errors to the C bits. Because of this error, an error in the first or second C bit for position 2 will be
incorrectly decoded if the first C-bit position is calling for a stuff and the second C-bit position is not. The end result
of this error is that both positions will call for a stuff, resulting in a bit being removed from the DS1 data stream. This
will force downstream equipment to experience a reframe.
The minimum time to false decode severity is as shown in Table VT-5 (in terms of seconds to false decode).
Table VT-5. Minimum Time (in Seconds) to
False Decode Severity of the C Bit
In the absence of an external bit error rate, the algorithm decodes these C bits correctly.
Test Pattern (TP) Generator/Monitor
TP-1. Test Pattern Insert
The transmitted test pattern comes out on the opposite edge with respect to the jitter-attenuated data.
TP-2. Test Pattern Drop
The test pattern detector always inverts the clock coming into the block before retiming the data.
Jitter Attenuation (JA)
JA-1. Jitter Attenuator
The digital jitter attenuator buffers are not functional. The DJACTL bit in register 0x01 should be set to 0 in this
device. Putting the device in the jitter attenuator mode (DJACTL = 1) causes loss of transmission.
