AMN1220 GMT

The AMN1220 GMT is a hardened triple-play ONT that can be tailored to multiple applications, including MDU and MTU applications through the use of application-specific circuit packs.

MDU Applications

In multi-dwelling unit (MDU) applications, the AMN1220 GMT can be equipped with up to 24 voice (POTS) ports and 12 10BASE-T/100BASE-TX Ethernet ports. An optional RF video port can be provided on the GMT main module. This port provides a high output (33dBm) RF signal that can be split among multiple end users. In multi-dwelling unit (MDU) applications, the AMN1220 GMT can be equipped with the following:

  • Up to 24 voice (POTS) ports
  • 12 10BASE-T/100BASE-TX Ethernet ports
  • 1 1000BASE-T port
  • RF video port (high-output)

MTU Applications

Business applications include Multi-Tenant Unit (MTU) applications in which multiple small businesses are supported in a multi-tenant building or office park setting, as well as single medium businesses. Data services that can be provided by the AMN1220 GMT include 10BASE-T/100BASE-TX ports and one Gigabit Ethernet port. T1 circuits can be provided, serving as voice and data network-side circuits for an enterprise telephone system such as a PBX (Private Branch Exchange).

The following can be equipped in MTU applications:

  • Up to 12 10BASE-T/100BASE-TX Ethernet ports
  • One 1000BASE-T port
  • Up to four T1 circuits can be provided, serving as voice and data network-side circuits for an enterprise telephone system such as a PBX (Private Branch Exchange). The AMN1220 GMT is a hardened ONT that can be tailored to multiple applications through the use of application-specific circuit packs. Available interfaces include standard voice (POTS), Ethernet (10BASE-T/100BASE-TX), Gigabit Ethernet (1000BASE-T), T1 (TDM), VDSL2, and RF video (optional). A battery backup option is available for lifeline POTS service.

The 8-port POTS modules provide the same functionality as the voice interfaces on the AMN1220 GST single family/single business terminal, providing consistency of services across the network. IDC or bulk Amphenol connectors are provided on the POTS module to allow simple installation of voice circuits.
