Description
PNS
[5:1] rwd-_-_
Port Number Select selects TDM Port associated with Bundle (PNS = 0 = TDM
Port #1, PNS = 31 = TDM Port #32).
PCRE
[0] rwd-_-_
Port Clock Recovery Enable.
0 = Do not use this Bundle for Clock Recovery
1 = Use RXP Bundle for Clock Recovery (enable Clock Connection)
BCDR5. A:00BCh
Bundle Configuration Data Register 5. Default: 0x00.00.00.00
RSVD
[31:25]
Reserved.
PDVT
[24:10] rwd-_-_
Packet Delay Variation Time selects minimum Jitter Buffer fill level required
before RXP payload data is forwarded to the transmit TDM Port. This function is
not used with Clock Only Bundles.
SAT Bundles with payload and SAT Clock Only Bundles
Forward data when fill level = PDVT * 32 TDM Port bit periods
CES Bundles with payload and CES Clock Only Bundles (set unused bits = “0”)
For Pn.PTCR1.BFD = 1: Forward when fill level = PDVT * 125 us; use bits [19:10]
For Pn.PTCR1.BFD = 2: Forward when fill level = PDVT * 250 us; use bits [20:10]
For Pn.PTCR1.BFD = 3: Forward when fill level = PDVT * 500 us; use bits [21:10]
MJBS
[9:0] rwd-_-_
Maximum Jitter Buffer Sense selects Jitter Buffer Overrun Fill level that
increments the Overrun Event Count (JEBEC). This function is not used with
Clock Only Bundles. This function does not generate an interrupt.
SAT Bundles: Overrun Fill Level = MJBS * 1024 TDM Port bit periods
CES Bundles: Overrun Fill Level = MJBS * 500 us
BESR1.
A:00C0h
Bundle Encap Status Register 1. Default: 0x00.00.00.00
PRHASL
[31] rld-cor-_
Port Receive HDLC Abort Status Latch = “1” indicates one or more HDLC Abort
codes have been detected on one or more receive TDM Ports.
RSVD
[30:20]
Reserved.
PRHEFC
[19:0] rld-cnr-nc
Port Receive HDLC Error Frame Count = number of receive TDM Port HDLC
frames with an error (including FCS, alignment, abort, too short or too long).
BESR2.
A:00C4h
Bundle Encap Status Register 2. Default: 0x00.00.00.00
GPTXC
[31:0] rld-cnr-nc
Good Packet TXP Count = # transmitted TXP packets (all Bundle types)
BESR3.
A:00C8h
Bundle Encap Status Register 3. Default: 0x00.00.00.00
RSVD
[31:5]
Reserved.
SHFSL
[4] rld-cor-_
Short HDLC Frame Status Latch = “1” indicates the size for one or more receive
TDM Port HDLC frames was < 4 bytes (including FCS bytes).
LHFSL
[3] rld-cor-_
Long HDLC Frame Status Latch = “1” indicates the size for one or more
received HDLC frames was > maximum size (including FCS; B.BCDR1.PMS)
AESL
[2] rld-cor-_
Alignment Error Status Latch = “1” indicates one or more receive TDM Port
HDLC frames had an alignment error.
CESL
[1] rld-cor-_
CRC Error Status Latch = “1” indicates one or more receive TDM Port HDLC
frames had a CRC (FCS) Error.
TXPSFSL
[0] rld-cor-_
TXP Packet Space Full Status Latch = “1” indicates one or more receive TDM
Port HDLC frames were discarded due to TXP packet buffer overflow in SDRAM.
BDSR1.
A:00D0h
Bundle Decap Status Register 1. Default: 0x00.00.00.00
JBLPDSL
[31] rld-cor-_
Jitter Buffer Late Packet Discard Status Latch = “1” indicates one or more RXP
packets discarded due to late arrival (Sequence # already passed; SAT/CES).
RSVD
[30:20]
Reserved.
PDC
[19:0] rld-cnr-nc
Packet stream Defect Count = # SAT/CES RXP packet stream defect events.
PC.CR21.PDCC 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.
