Modular approach to networked communications sets Green-GO apart from other intercom brands What sets Green-GO intercom apart from other intercom brands is its modular approach to digital networked communications. With no matrix or base station required, an entry-level system can comprise of a handful of wired belt packs, appropriate headsets and an unmanaged PoE switch. Despite their compact design and regardless of system size, each device has access to 32 channels with a full 16 bit, 7 kHz dynamic range by default. Coupled with low data bandwidth and latency, Green-GO comms can sit on virtually any data network with minimal impact. Straight from the box, belt packs come with a factory default configuration. If there is no domain host available on the network to supply IP addresses, the belt packs will automatically set their own addresses. Simply plug each belt pack into a separate port on a PoE switch to establish communications. As technical requirements and budgets grow, the system expands by simply adding more devices whenever the need arises. Green-GO wireless belt packs operate in the 1.9GHz DECT spectrum, which is licence-free in Europe, the USA, and many other countries. They share the same specifications and operating system as the wired packs so swapping between the devices is relatively intuitive. Interfacing with external audio systems including intercom is comprehensive and robust. Analogue in/out, party line linking, Dante and multisite/remote connection capabilities make the selection and application of products very diverse, suitable to work to your requirements and workflow, making Green-GO digital comms a very versatile system. More so given the current global concerns, customers throughout various industries consider alternatives to being physically present at events and communications is a key part of that. Looking at solutions for remote working the
26-781 GGO-BRIDGEX Is a very useful tool for multisite/wider network communications, not only for linking international sites but also for supporting connections over wireless links or strictly managed internal networks. Splitting the workforce, linking two or more complete systems together on a handful of channel is viable option in a variety of applications.Yet the ability to linking individuals to a host system currently appears to have the greatest appeal. Typically, we find Remote workers using a 26-775 GGO-BPX wired belt pack or were needed a 26-788 GGO-MCXD multichannel station, Establishing communications to the event space through their home or hotel router. Alternatively for venues were Green-Go is not already present, An innovative extension of the ‘Remote’ concept utilises a 26-768 SGOO-SI2W 2-Wire interface or 26-769 GGO-SI4W 4-Wire interface as remote users. Linking directly to party line systems or presenting channels as an analogue line in/out, allowing established comms systems to communicate externally with relative ease.
Bridging logic “Bridging” in Green-Go terminology refers to establishing communications between two or more different local access networks (LAN) via the internet or wider access network (WAN). Each 26-781 GGO-BRIDGEX supports up to four independent streams/connections with each link requiring its own unique UDP port allocation to establish a Point to point connection. Multiple devices can be utilised in a given system, requiring approximately 500Kbps per streams/connection, the limitation on maximum capacity is your internet service provider (ISP) bandwidth.

26-788 GGO-MCXD
In every connection, we have an active and passive component, the passive component is always a Bridge, But the active components, can be a Bridge (Group Bridge) or wired Green-Go device (remote user), depending on the type of connection desired. Group Bridge mode two separate and independent Green-Go intercom networks, each with its BridgeX interface, creating an intercom group per stream that is common between sites.

‘out over’ network A
Wired device to Bridges connections (remote user) allow a single device to become a full member of the host system
The system attached to network A has a group channel that is linked through its BridgeX ‘out over’ its local gateway looking for the public address to network C. The connection then goes ‘in over’ from the external address of network C to its passive bridge, communicating to its local system on given group channel. Remote User mode a single GreenGo device per stream connects to passive BridgeX from a separate network and becomes a full member of the host system. The Device attached to network B looks directly ‘out over’ its local gateway (via a switch for PoE) looking for the same address of network C but on a different predefined UDP port number. The connection then goes ‘in over’ from the external address of network C to the passive bridge alike before, providing the remote device access to all the channels and functions you would expect if connected locally. “Active” connections do not typically require any network address translation (NAT) ruling to see ‘Out over’ their network, whereas “Passive” connections require port forwarding to translate the request ‘in over’ through their local networks firewall.
