Chapter 2: Site Preparation
Network and Backhaul Requirements
Before you begin installing the NPM basestation, see the Amosphere System
Overview for a description of network requirements and consult your field
engineering package (FEP) for information involving the network equipment.
PSTN Gateway
The NPM basestation does not connect directly to the PSTN. A PSTN gateway,
such as a PRI, connects the Amosphere IP-based equipment to the
circuit-switched PSTN.
NOTE: Ensure that any equipment connecting the basestation
to the PSTN is UL-listed.
Edge Routers
The NPM basestation requires a connection to at least one edge router
configured to direct packets between the basestation and the network core. The
basestation connects to the edge router using 100-Mbit/s Ethernet.
Backhaul Circuits
See your preliminary RF design package for information about bandwidth
requirements for the backhaul.
See your field engineering package information about your site’s backhaul
circuits and the configuration of any necessary customer service units (CSUs).
NOTE: Backhaul circuits must be tested by qualified personnel
before the NPM basestation is placed into operation in order to
ensure connectivity with the core servers.
Internet Gateway
See your field engineering package (FEP) for Internet gateway connectivity
information.
