Connections and Cabling
Cabling to Support SMPTE ST 2022 - 7 with a UCP - 3901
The optional Cat5 Ethernet cable is not necessary when a specific configuration option is
used. See Connecting to the Multiviewer SDC with RollCall , on page 39.
Cabling to Support SMPTE ST 2022 - 7 with a UCP - 3901
The UCP - 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.
PREREQUISITES:
• 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 106.
• For the UCP - 3901, in both Rollcall’s Input Spigot panel and Output Spigot panel, make
sure to change the Streaming type to Dual . See Input Spigots , on page 81 and Output
Spigots , on page 85.
