CDM-710/L Broadcast Satellite Modem
Front Panel Operation
WAN Port Statistics:
• WAN Octets (Out) – The sum of the lengths of all Ethernet frames that
are forwarded to the WAN.
• WAN Unicast (Out) – The number of good frames with unicast destination
MAC addresses that are forwarded to the WAN.
• WAN Broadcast (Out) – The number of good frames with broadcast
destination MAC addresses that are forwarded to the WAN.
• WAN Multicast (Out) – The number of good frames with multicast
destination MAC addresses that are forwarded to the WAN.
• FPGA Media Received – When FEC is enabled, indicates the number of
media packets received by the FEC logic; does not include FEC packets.
• FPGA Media Recovered – When FEC is enabled, indicates number of bad
or lost Ethernet packets which have been recovered using FEC.
• FPGA Media Unrecovered – When FEC is enabled, indicates number of
bad or lost Ethernet packets that could not be recovered, for which a
packet with a payload of null MPEG packets has been substituted.
• FPGA UDP Checksum Error – Indicated number of Ethernet packets
received with incorrect UDP checksums.
• FPGA Non-Compliant Pkt – Indicates number of Ethernet packets
received which are not valid transport stream packets.
• FPGA Packets Dropped – Indicates number of IP packets that have been
dropped due to a buffer overrun condition.
• FPGA Null Underrun – Indicated number of Null MPEG packets generated
to the WAN due to buffer underrun conditions.
• FPGA Null Out-of-Sync – Indicates the number of null MPEG packets that
have been generated to the WAN due to a loss of (MPEG packet)
synchronization condition.
• FPGA Overrun Events – Indicates the number of times that a buffer
overrun condition has occurred.
• FPGA Underrun Events – Indicates the number of times that a buffer
underrun condition has occurred.
• FPGA Out-of-Sync Events – Indicates the number of times that a loss of
MPEG synchronization condition has occurred.
• WAN Good Octets (In) – The sum of lengths of all good Ethernet frames
received from the IP encapsulation logic.
• WAN Unicast (In) – The sum of good frames received from the WAN IP
encapsulation logic that have a unicast destination MAC address.
