WISCONSIN’S BADGERNET CONVERGED NETWORK
The Department of Administration’s BadgerNet converged network (BCN) is a statewide network
that enables State government and its Authorized Users in all seventy-two counties to purchase a
single access circuit with multiple services. The BCN provides wide area network (WAN) service,
interactive video service, and Internet transport service. BCN users select which service(s) they
want to purchase along with an increment of bandwidth for each service(s).
BCN access circuits are provisioned in a variety of increments of 256K through Gigabit speeds. The
access circuit carries all chosen services to an aggregation node, which routes traffic to the
respective destinations.
Bidders awarded a contract from this RFB will be authorized to connect to the BCN POP in each of
the four (4) LATAs in the following cities: Madison, Milwaukee, Green Bay and Eau Claire. Internet
traffic from authorized BCN network users connects with their chosen ISP via the appropriate POP
depending on LATA location.

END-USER LOCATION
BCN Internet Transport Service (ITp) at the end-user location consists of four (4) major
components. First is the BCN transport circuit that the ITp service will use to carry Internet traffic.
Second is the BCN Customer Edge (BCN CE) used to connect to the BCN transport circuit and deliver
the ITp service through an Ethernet port labeled “ITp.” This component will be either a switch or
router that is managed by the WBAA Telco partner working with AT&T. Next, is the customer
premise equipment (CPE), owned by the customer or provided by an ISP that terminates the ITp
service. This device can be a firewall, router, Layer-3 switch or appliance, or Layer-2 switch
connected to a Layer 3 device. The final component is an Authorized User provided straight
through or crossover Ethernet cable. This cable connects the Authorized User CPE to ITp port on
the BCN CE. The cable type is dependent on the device the Authorized User is attaching to the BCN
CE. The following diagram depicts the Authorized User location.

BCN POP LOCATION
Bandwidth Option
There are two Ethernet interface options available in each BCN POP location, one (1) Gigabit or ten
(10) Gigabit. The one (1) Gigabit interfaces are currently available at each of the four BCN POP
locations. The ten (10) Gigabit interfaces will be available in the near term at each of the four BCN
POP locations. Allow lead-time of up to 85 business days to order, install, configure, test and turn
up each ten (10) Gigabit port in each BCN POP location. The ten (10) Gigabit Ethernet interface
includes a cold-standby redundant port. In the event of a card or port failure, the cold stand-by will
be placed into the router chassis as soon as a service technician can arrive at the core node.

POP Connectivity
BCN ISP POPs are collocated in a Windstream office in each of the four LATAs. The Contractor must
acquire connectivity from their own POP to a Windstream office, which is collocated in all four (4)
BCN POP locations. The Contractor may connect to the Windstream POP equipment in one of the
following (4) ways:
1. Purchase intra-city transport from Windstream between the AT&T serving wire center and
one of the four (4) Windstream POPs.
2. Via a pre-existing or anticipated direct fiber interconnection system properly established
between the Contractor and Windstream.
3. Via an existing Competitive Local Exchange Carrier (CLEC) interconnection that has been
established at the Windstream POP.
4. Via network transport purchased from Windstream from elsewhere on the Windstream
Network to one of the POPs.

The standard transport charges apply to any circuit connecting the ISP to the Windstream POP.
Once inside the Windstream POP there is no cross connection charge for the optical Gigabit
Ethernet interface at the BadgerNet ISP POP. Should the Alternate ISP desire to bring a
Synchronous Optical Network (SONET) circuit into the Windstream POP, the contractor will be
required to provide and co-locate in the Windstream POP media conversion equipment capable of
converting the circuit from SONET to Gigabit Ethernet.
Should a Contractor desire to be physically collocated in the Windstream POP housing a router,
rack space, AC and DC power; Windstream Technical Service charges will apply, in addition to
charges associated with all of the options detailed above for accessing each Windstream POP. To
collocate at a Windstream POP, the process involves the prospective Contractor to complete and
return a Windstream pre-collocation checklist specifying their space and power requirements,
types of equipment desired to be in the co-locate and their HVAC requirements. Assuming
Windstream can accommodate the needs of the Contractor, a mutually executed Collocation
Agreement between Windstream and the Contractor is required prior to the installation of
Contractors equipment at a Windstream POP.
The process of connecting to the Windstream POP core router for service is that of any standard
order for private line service, specifying A and Z ends of the transport medium, speed of the circuit
and the desired length of the initial term of the service. The service order will be placed with the
designated Account Executive at Windstream assigned to the Contractor. Providing service to a
Contractor that does not currently do business with Windstream requires that the Contractor a)
execute Windstream’ s standard Non-Disclosure Agreement, b) apply for and pass Windstream’ s
standard Non-Disclosure Agreement, c) apply for and pass Windstream’ s credit approval process,
and d) execute a service agreement for the requested service to be provided.

Limited BCN Core Transport
To allow smaller ISPs flexibility to provide services to customers within LATAs where the ISP may
initially find it cost prohibitive to establish a Point of Presence, the BCN will aggregate 200 Mbps of
Internet transport across the BCN core network.
An ISP that wishes to take advantage of the BCN core transport will first choose to hub traffic at a
minimum of one (1) BCN POP by establishing a point of presence.
The diagram below describes one way in which an ISP may utilize this bandwidth. In the example,
the ISP has chosen the Green Bay LATA 350 (bottom) BCN POP as its point of presence. The BCN
will then establish two (2) VLANs in Green Bay, one (1) for Internet transport traffic that originates
from within Green Bay LATA 350, while the second VLAN carries traffic from LATAs in Milwaukee
(LATA 356), Madison (LATA 354), and Eau Claire (LATA 352). There is no rate limit for traffic
originating from the Green Bay LATA 350 (blue VLAN).
The second VLAN connecting the ISP to the Green Bay LATA 350 Core node is shown in red. This
VLAN carries the combined traffic from the other LATAs and is rate limited to 200 Mbps. The ISP
has the option to split the 200 Mbps among the other LATAs in as many increment of 5 Mbps that it
wants. In the diagram below, the ISP requested 90 Mbps across the BCN core from Madison LATA
354 and Milwaukee LATA 356, but only 20 Mbps from Eau Claire LATA 352.
BCN will regulate the ingress and egress rate limit for traffic within a LATA, but the ISP has to
determine if or by how much it might oversubscribe that interface.
As customer volume increases, the ISP has some flexibility in its growth path. The first step might
be for the ISP to re-configure its 200 Mbps of bandwidth by increasing the bandwidth allocated in
one LATA and decreasing the bandwidth allocated in another.

Eventually, the ISP may determine that a growing customer base will require it to establish
additional points of presence at other BCN POPs and back-haul that traffic outside of the 200 Mbps
limit within the BCN core. In this case, the ISP will provide instruction to BCN regarding the path its
customers will take.
