Specifications include, but are not limited to: San Bernardino County’s Wide Area Network The County’s WAN is a telecommunications network that interconnects geographically dispersed users. In the case of the County, this network allows the geographically dispersed County departments to share data, run applications, participate in video conferencing (which reduces large amounts of travel time in a county the size of San Bernardino County), communicate via email, and access the Internet all of which assist the County departments in serving the public. Historically, the WAN was solely a data communications network, and the County had a separate voice network. With technology advancements (VoIP), the voice traffic is now converging with the data network and running on the WAN. All San Bernardino County departments utilize the WAN and it covers all the cities and towns in San Bernardino County where County offices are located. In addition to County departments, non-county agencies, such as city, school, and military police departments securely connect to the WAN to allow them to access various law enforcement applications that are available through San Bernardino County. San Bernardino County’s Telecommunication Voice Network The voice network consists of networked clusters of Cisco equipment with multiple nodes per cluster. The nodal equipment is connected via leased telephone company lines, SIP trunking, and/or the County’s microwave/radio network, with multiple T1s between nodes. The subtending switches are networked via T1/TIE lines/SIP trunks. Whenever possible, traffic is routed over County TIE lines. Overflow traffic is carried on the PSTN. Local and Zone 3 traffic use the PSTN, unless the call is from a County switch to a County switch. The County network currently handles all County on-net calls with San Bernardino County. The County reserves the right to maintain this service or let the successful proposer(s) provide this service. Currently the County is using one IXC carrier for InterLATA/Interstate calls. This IXC carries calls from each of the three Nodes and incoming 800 services. The County is using approximately 105 toll free numbers (800 numbers) which are provided via various carriers and entry points throughout the County. The County maintains an internal 5-digit dialing plan (County switch site to County switch site), using approximately 45,000 DID numbers. Due to the complexity of establishing a dialing plan of this magnitude, the County requires the existing telephone numbers and dialing plan to remain the same.
