4.5.6.1 Network Configuration Fields
Field
Description
Network Name
Create a unique network name that will be referenced during creation of any networked profile.
The Network Name is limited to 8 characters and may only include letters, numbers or a hyphen '-'.
VPN Certificate
A reference to a VPN configuration. Upload VPN certificates from the VPN certificate tab.
If no VPN is to be used select None.
IP Address
IP Address the GoBox will use when this operational profile is used. The GoBox will reconfigure its network
interface and IP address to this value when selected.
Subnet mask
The subnet mask the GoBox will use when this operational profile is selected.
Default gateway
The default gateway the GoBox will use when this operational profile is selected.
RNC IP Address
The static IP Address of the RNC that the GoBox will register with and will be used to perform multi-site
repeating.
RFSS ID
P25 Radio Frequency Sub-System ID.
System ID
P25 System ID.
Allowed values are hexadecimal (000 to FFF)
Group ID
P25 Network Talkgroup ID.
Allowed values are hexadecimal (0000 to FFFF)
High Latency / Unreliable
Link
When checked, the GoBox will perform PTT arbitration locally instead of needing a round-trip to the RNC to
enforce the talking party.
This field can be checked to reduce repeat delay if there is a backhaul link between the GoBox and RNC
that is slow or disconnects often (e.g. satellite).
Several “Advanced Options” are also available by clicking on the “+” to expand the form:
Field
Description
Control Traffic DSCP
Differentiated Service Code Point for Control Traffic
A classification parameter for network traffic between the GoBox and an RNC or DFSI host. It is used to
provide QoS.
The DSCP must be between 0 and 63.
Voice Traffic DSCP
Differentiated Service Code Point for Voice Traffic
RNC Poll Period
A SIP Options request will be sent to the RNC at the supplied interval to determine the connection status.
On a metered network connection, this figure can be increased to reduce connection costs associated with
this action.
The poll period must be between 0 and 30 seconds.
Voice Frames Per RTP
Packet
The number of voice frames within each RTP packet sent into the network.
On a metered network connection, this figure can be increased to reduce connection costs.
Valid values are 1, 2, or 3.
Keep Network Calls Alive
When checked, the GoBox will attempt to re-establish the RTP connection associated with a network group
if it is torn down by RNC.
On a metered network connection, disabling this can reduce connection costs if the P25 network regularly
tears down the talk group.
The recommended default is checked.
4.5.6.2 VPN Certificate Management
The GoBox supports using a VPN connection to establish a secure network tunnel between itself and a remote server via
the use of OpenVPN. The GoBox is the VPN client and expects to establish the connection with a VPN server. To view and
add new VPN connections, click on the Network Configurations administrator option and then click the VPN Certificate
Management tab.
