PN-4407 (to be published as TIA/EIA TSB-110)

provide an adequate environment for the operation of the RG, including power supplies, ventilation and mechanical protection from the elements.

5.2.2 Internal Digital Interface

The internal digital interface shall comply with all requirements of the PCI Local Bus standard

5.2.3 Plug-in Modules

The plug-in modules (AGMs, PNMs and SMs) provide the necessary flexibility to address the ongoing technology evolution in the service delivery and consumer products arena. Because the plug-in modules may be installed by a low-level technician or by the resident, the form factor for the devices should be rugged, consumer friendly, and plug-n-play capable. The plug-in modules shall be based on open industry standards to insure interoperability of modules provided by a number of suppliers. These modules shall employ technology and form factors as specified in the PCMCIA "PC Card" standard.

Such plug-in modules may require the use of a cable or dongle to interface with external associated media or ancillary apparatus.

5.2.3.1 Access Gateway Modules

The Access Gateway Modules (AGM) shall be specific to each service delivery technology and shall terminate the access at standard physical and electrical interfaces. Some AGMs may incorporate special equipment (e.g., antennas, transceivers) needed on customer premises; and some may be physically divided between internal and outdoor chassis elements for environmental or service delivery reasons.

The types of service delivery technologies foreseen at this time include but are not limited to:

  • Twisted pair, carrying POTS, ISDN BRI, or xDSL modulations.

  • One or two-way analog or digital coaxial cable, frequency divided into channels. Currently this medium is primarily used for video broadcast and may also be used for high-speed data, voice, and digital video.

  • Fixed wireless loop, narrowband media using analog or digital technology related to cellular, PCS, MMDS and others.

  • Direct broadcast satellite, including a satellite dish and other special video reception equipment including satellite or terrestrial uplinks.

  • Broadband microwave systems such as multi-Gigahertz, terrestrial or satellite cellular technologies.

  • Optic fiber networks, carrying high-bandwidth, multi-wavelength analog and digital

applications.

  • Powerline networks, including energy management and information services.

        • 5.2.3.2

          Premises Network Modules

The Premises Network Modules (PNMs) shall be specific to each in-home network and shall terminate the associated network at standard physical and electrical interfaces. Some PNMs may incorporate special equipment (e.g., antennas, transceivers) needed on customer premises.

The kinds of customer premises systems/networks foreseen at this time include but are not limited to:
