Who Can Use This Service?
OTM provides Data Dial Tone and DMZ Services to state agencies in the Capitol Park Complex in downtown Baton Rouge as new buildings in the complex are opened for occupancy, as well as to other locations deemed part of the "LSI virtual campus".
Subscription to Data Dial Tone services requires that the agency participate in the State's private Intranet. The State has created a private IP addressing scheme to be used by all participants. OTM assigns private and public IP address ranges to each agency. Agencies should be aware that conversion to the standard private addressing scheme is required in order to subscribe to Data Dial Tone services.

Data Dial Tone Service Offerings

  • Data Center and Building Connectivity
    • Desktop Access is used in the buildings served by Data Dial Tone to provide 10/100Mb access for PCs, network printers and in-building servers.
    • Server Access is used in the shared Data Centers to provide 10/100/1000Mb access for agency private and public servers and mainframes.
    • Network Access is used in the buildings or data centers for connecting an agency access switch to the OTM aggregation switches.  Note:  This type of access is only available in certain special cases. Most connectivity will now be provided via Desktop and Server Access.
  • DMZ--Agencies that offer on publicly accessible servers must subscribe to Data Dial Tone DMZ services. Agency public servers are placed in a secured Demilitarized Zone and are protected by OTM-provided firewalls. An agency purchases a Server Access port for each device located within the DMZ and connects those public servers to the OTM DMZ switch. In addition to the access port(s), the agency purchases bandwidth for its collective group of servers located within the DMZ network. (See diagram)
  • VPN--The Data Dial Tone VPN (Virtual Private Network) service provides secure, encrypted remote access to the Intranet from remote locations. This service is available for authorized individuals who need access to the network from remote locations as well as for small remote offices that need secure connectivity back to their agency's internal data center resources. Each agency maintains their own database of authorized users, and OTM proxies to those agency authentication servers. An agency may purchase access for their collective remote user group and/or for each of their remote offices on a bandwidth subscription basis. OTM does not limit the number of users allowed from each agency.

    area of each Data Dial Tone building, generally the first floor where multiple
    shared conference rooms and/or training rooms are located. Agencies will also
