Chapter 2: Site Preparation
Network and Backhaul Requirements
Before you begin installing the base station, read the following network requirements. See the
following documents for detailed information about network and backhaul requirements:
 Network Deployment Planning Guide – describes site, network, and backhaul requirements
 System Overview – describes the role and function of equipment in the network core
Edge Routers
The base station requires a 100-Mbit/s Ethernet connection to at least one edge router configured to
direct packets between the base station and the network core. Ensure that your base station site can
accommodate the electrical, environmental, and physical requires of the edge routers.
Backhaul Circuits
Multiple T1, DS3/E3, or other interfaces connect the edge routers at the base station site to the
network core. 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 base
station is placed into operation in order to ensure connectivity with the core servers.
PSTN Gateway
The base station does not connect directly to the PSTN. A PSTN gateway located in the network core
connects the IP-based equipment to the circuit-switched PSTN.
NOTE: Ensure that any equipment connecting the base station to the PSTN is
UL-listed.
