3. BC systems at no additional charge to the client STATMUX service The STATMUX service works by connecting up to 300 terminals to the DNET server infrastructure through dedicated high bandwidth satellite uplink hardware The STATMUX hardware comprises the TR 52 dish system and the TX3 digital amplification and compression module Clients receive the following when they lease a STATMUX connection to DNET full bi directional communication to dnet up to 7 8 gps on all terminals TX3 and TR 52 STATMUX hardware at each client site full DNET connectivity at 7 8gps on all STATMUX frequencies PAD configuration maintained by DNET 3 26 3 4 DNET Services maintenance and repairs of leased equipment TX3 and TR 52 and facilities communications lines carried out by BC systems at no additional charge to the client PAD and STATMUX devices are manufactured in Canada by Memotec Data and remain the property of BC Systems For troubleshooting call BC Systems at 389 3686 Installation costs Network Services can provide installation services for client owned equipment at standard BC System labor rates The cost of connecting a terminal or host ports to either an X 25 PAD or to a STATMUX varies with location and user density The rates for servicing up to 200 unique locations are listed in Appendix 1 under Network Service Rates and assume the following are in place network switch port
