Connections and Cabling
Cabling to Support SMPTE ST 2022 - 7
Fig. 4-2: Typical XIP - 3901 Network Cabling when the XIP - 3901 is used with Densité frames that are
equipped with Densité 3+FR4 STD or Densité 3+ FR4 ADV frame controller that is connected to the
Management IP network.
Cabling to Support SMPTE ST 2022 - 7
The XIP - 3901 supports network redundancy, for use with any SMPTE ST 2022-7 compatible
equipment.
To make streaming more reliable over an IP network, the implementation of SMPTE
ST 2022-7 seamless protection switching depends on stream redundancy. This protection
scheme transmits two identical packet streams over physically separate network routes
(shown as Media Red LAN and Media Blue LAN in the figure below), so that if packets from
one route are lost, the data can be reconstructed using packets from the second stream.
This process is seamless because switching between the streams is instantaneous and does
not impact content.
PREREQUISITE:
• At least two DCNM-compliant switches must be used for this application. Contact Grass
Valley for more information about switch compatibility. See Grass Valley Technical
Support , on page 308.
