1 IPG-4901 WAN IP I/O Gateway for GV Node
1.1 Introduction
The GV Node IP Gateway (IPG-4901) plug-and-play module from Grass Valley, a Belden Brand, is a 3 RU single slot
module for the GV Node frame, which offers bidirectional fiber IP connectivity.
Not all IP signals are created equal. While Grass Valley provides a very complete IP solution, there will still be
requirements to provide conversion to/from other equipment that supports IP standards that are incompatible. The
IPG-4901 IP Gateway provides a robust feature set for normalizing variances in IP signals sent to GV Node or GV
Matrix I/O.
WAN IP connectivity:
The IPG-4901 leverages the full SMPTE ST 2022-7 Class A specification to ensure
uninterrupted reception of high jitter signals from remote sources and SW based transmitters. The IPG-4901 can be
fitted with multimode or singlemode SFPs to provide connectivity up to 10 km (6.21 mi.).
Signal conversion with audio DEM/EMB:
In conjunction with the GV Node 40G aggregation ports, the IPG-4901
can be used to convert SMPTE ST 2022-6 and AES67 signals from the WAN to SMPTE ST 2110-20/30/40 signals on
the LAN. Each IPG- 4901 module has bidirectional 10G Ethernet ports that support up six 3 Gb/s sources or nine HD
sources with AES67 audio DEM/EMB.
Signal Alignment:
The IPG-4901 provides a full alignment capability with up to two frames with respect to the GV
Node switching fabric, and is available for any SMPTE ST 2022-6 signals and AES67 audio, in both aggregation and
redundancy modes.
Alignment capability provides a clean switching of any of the sources from the IPG-4901.
The IPG-4901 I/O module may be combined in the same chassis with other GV Node or GV Matrix modules to create
an even more versatile distributed edge-routing node.
The GV Node IP Gateway can be controlled by the advanced GV Convergent SDN platform, offering unified control
across COTS IP switches and SDI routing/processing infrastructures, as well as by the proven iControl systems.
