5.4.6 Seamless IP Input
The Seamless IP input module allows two input interfaces to be connected to different
network sources, but for the system, this is a single module. The same multicasts are
subscribed to on both interfaces. These multicasts must come from the same source.
All function and status normally associated with IP input cards are present for the logical
module. In addition data rate, sequence errors, and relative delay for each stream are
reported for every input.
Moreover, alarms related to the network interface and stream alarms (e.g. “No bitrate”)
appear as warnings if they occur only on a single interface. “Link down on interface A or B”
is a major alarm. If alarms appear on both interfaces, they will act as for normal IP input
cards, and be a single alarm with the same alarm ID as used on other IP input cards.
The following information is displayed in status parameters for Seamless IP Input configuration:
Module
Slot position in the chassis
A and B both will be displayed.
Type of input module : ipswitch
Input Rate
Number of services present in the transport stream
Input Rate of active services for both A and B will be displayed.
Total bandwidth of the incoming transport streams.
Number of Continuity Counter (CC) errors detected on all input ports
since last reset; CC errors indicate that one or more packets are lost.
Number of Transport Stream (TS) errors detected on all input ports.
TS errors indicate problems with the incoming TS structure of the
streams
Real-time Transport Protocol sequence errors since last reset (applies
to both Port A and port B)
Rate of active services transmitted to the backplane
