Description
Bundle Decap Status Register 2. Default: 0x00.00.00.00
Reserved.
Jitter Buffer Event Count = # SAT/CES RXP packet stream defect events.
PC.CR21.JBECC selects which defect conditions are counted. BDSR1.PDC and
BDSR2.JBEC can be programmed to count the same or different conditions. Not
valid for Clock Only Bundles. For HDLC Bundles only Overruns can be counted.
Bundle Decap Status Register 3. Default: 0x00.00.00.00
Reserved.
Jitter Buffer Low Level = lowest Jitter Buffer fill level since last read. A read
operation forces JBLL = “all ones” until next Jitter Buffer current level available.
When Underrun is reached, the value remains zero until it is read by the CPU.
The # JBLL bits is equal to the # JBCL bits (not valid for HDLC or Clock Only).
Reserved.
Jitter Buffer High Level = highest Jitter Buffer fill level since last read (not valid
for HDLC or Clock Only). A read operation forces JBLL = “all zeros” until next
Jitter Buffer current level available. When Overrun is reached, JBHL =
B.BCDR5.MJBS until read by CPU. The # JBHL bits is equal to the # JBCL bits.
Bundle Decap Status Register 4. Default: 0x00.00.00.00
Good Packet RXP Count = # received good RXP packets (all Bundle types)
Bundle Decap Status Register 5. Default: 0x00.00.00.00
SAT/CES Jumped/Lost Packet Count indicates how many Jumped or Lost
Sequence # conditions have been detected (according to G.GCR.JLPC).
SAT/CES Bundles – accumulated difference between expected and received
packet Sequence #. Total Missing Packets can be calculated with:
HDLC Bundles (Jumped Count only) – accumulated difference between expected
and received packet Sequence # for difference < 32,768 (see B.BSDR6.SCRPC).
Bundle Decap Status Register 6. Default: 0x00.00.00.00
Reserved.
SAT/CES Reordered/Duplicate Packet Count indicates how many Re-ordered
or Duplicate packet conditions have been detected (according to G.GCR.RDPC).
SAT/CES Bundles - # successfully Re-ordered or Duplicate packet events.
HDLC Bundles - # RXP packet with a Sequence Number Jump > 32,767.
Bundle Decap Status Register 7. Default: 0x00.00.00.00
Reserved.
SAT/CES Payload Size/Sequence Error Status Latch.
SAT Bundles: “1” = 1 or more RXP packets with payload size ≠ B.BCDR1.PMS
CES Bundles: “1” = 1 or more RXP packets with payload size ≠ B.BCDR1.PMS
(for CES with CAS this test function includes the expected CAS Signaling bytes).
HDLC Bundles “1” = 1 or more RXP packets with late or early Sequence Number
Jump > 32,768.
Total Missing Packets = Jumped Packets – Re-ordered Packets
= (B.BSDR5.SCJPC – B.BSDR6.SCRPC)
