This excerpt taken from the IPCS 10-K filed Dec 23, 2005.
The effective operation of our network requires:
· public switched and long distance interconnection;
· the implementation of roaming arrangements; and
· the development of network monitoring systems.
Our network connects to the public switched telephone network to facilitate the origination and termination of traffic between the wireless network and both local exchange and long distance carriers. Through our arrangements with Sprint PCS and Sprint PCSs arrangements with other wireless service providers, our subscribers have roaming capabilities on certain other PCS networks utilizing similar CDMA technology. We monitor our network during normal business hours. For after-hours monitoring, the PCS Network Operating Centers of Sprint PCS provide 24-hour, seven-day-a-week monitoring of the Sprint PCS network in our territory and real-time notification to our designated personnel.
As of September 30, 2005, the portion of the Sprint PCS network in our territory included 1,488 base stations and five switching centers.
