Noxium’s PRIME Telecommunications Gateway is an industrial cellular communications gateway which includes a PLC interface for communications with SMART-METERS. GTP brings together Noxium’s Routex reliability and security with PLC’s communications versatility providing an ideal solution for SMARTGRID networks with last generation intelligent meters.

General Information

  • From a Security stand point, GTP enables dynamic tunneling, information encryption and smart routing.
  • GTP also includes a switch wich offers great versatility when configuring different services or applications co-existing in the same infrastructure.
  • Its flexible configuration and WLAN’s offer a wide range of routing options.
  • In Highly available environments, this device operates with redundancy and self-monitoring in an active-active configuration, ensuring low latency delays and enhancing re-activation time. Always in a secure communication environment. In addition, there are GTP versions with Radio redundancy.
  • High MTBF and low maintenance costs are achieved using SNMP, Syslog, debugging and diagnosis tools as well as remote configuration and update features.



  • Compact, ergonomic and easy to instal, use and diagnose. Configurable PLC Communications on Service Node or Base Node with network topology auto-discovery. Compatible with DLMS systems and PRIME PLC communications.
  • It incorporates advance switching functions such as Tagged VLAN and VLAN Discriminated Services.
  • ACL, NAT, PAT and MAC filtering.
  • WAN services Multiplex via auxiliary modem or routers. Redundant VPN Tunnel set-up with active service surveillance. It supports DMVPN (GRE+IPSec+NHRP) up to 4 tunnels (2 tunnels/SIM).
  • Programmed re-boot to enable recovery after failure. Firmware OTA, via FTP, STFP and TFTP.
