The Importance of Training Course Offerings
Make Your Training Effective
In brief, we offer the following seven courses. Click as indicated on the desired class for a complete course description. All can be customized to meet your particular needs.
  • Fundamentals of T-1 and T-3 Networks is an intensive two-day seminar that concentrates on the nuts and bolts of T-carrier networks, with special focus on T-1 framing, synchronization, timing, ones density issues and channel bank multiplexing. Acronyms such as ESF, D4, B8ZS and AMI coding are fully explained in a uniquely comprehensible style. The meaning of DSU/CSUs and DTE/DCE terms is a central topic. Students configure T-1 DSU/CSUs in several ways and learn how to use the free troubleshooting tools built into every modern-day DSU/CSU for both nondisruptive monitoring and disruptive testing.
    IP Addressing and Subnetting is a one or two-day class intended to convey the concept, implementation and calculation of IP address schemes and subnet masks. We use a simple, unique approach that makes acquiring this crucial skill as easy as possible. In-class demonstrations and exercises are the core of this seminar. Once students can calculate masks and addresses by hand, several subnet calculators are introduced and analyzed with respect to their pros and cons. However, by the time this point is reached, most students will discover that they do not need them.
     
  • Fast Networks is a two-day investigation of the latest in network technologies: including T-1 deployment schemes; SONET; frame relay; ATM; Gigabit Ethernet and DSL. Some clients prefer to focus on elements of this class rather than do a complete overview. For this reason, each workbook chapter is quite comprehensive. This class is in presentation form and includes paper labs and exercises. The workbook is approximately 450 pp. and includes a reference section.
  • The following classes require a training room with LAN-equipped computers. Data Dynamics supplies all other equipment including hubs, routers, switches, cables and software.

  • Hands-On Introduction to TCP/IP is a very unique two-day class. It explains and demonstrates the five core functions of  TCP/IP in simple English. Students learn about the OSI Model as applied in the real world and how it relates to TCP/IP. They experience each of the five functions of TCP/IP by building a LAN and then installing, addressing and testing TCP/IP on the LAN. In this way we tie theory and fact together into a cohesive learning experience. As with all Data Dynamics classes, this class is fully hands-on. This class is a recommended prerequisite to the router class described next.

  •  
  • Hands-On LANs, WANs and Cisco Routers is intended for those who want to gain experience in the full range of skills required to make a router-based network run. It is five days in length. We begin with a discussion of encapsulation techniques for LANs and WANs including SNAP, ARP, PPP and HDLC. We then build a routed network using Cisco routers. Students perform all connection, configuration, and necessary troubleshooting to create a fully functioning intranet in the room. Routing techniques include configuring static routes (two types), RIP and OSPF, both singly and in combination. A key feature of this class is a full discussion of IP addressing and subnetting. Students develop an addressing plan, calculate appropriate subnet masks and then configure the routers and demonstrate that their scheme works.

  • Completion of this class qualifies a student to take the following two classes, in either order:
     

  • Hands-On Frame Relay: Principles and Practices is intended as a sequel to the router class above. Since over 80% of routers are connected to frame relay networks, it makes sense to show how routers and frame relay work together. This course assumes little or no prior knowledge of frame relay internals; these are explained on the morning of the first day of this two-day class. Students use routers to set up frame relay interfaces and then connect to a frame relay switch which is part of the class. Terms such as subinterfaces, IARP, DLCIs, LMI, LAP-F, BECN, FECN and CIR are demystified. Cisco router commands for frame relay are introduced and students run them in order to see why they are needed. This class assumes familiarity with IP addressing and Cisco routers. Students should have taken Hands-On LANs, WANs and Cisco Routers beforehand or have equivalent router experience.

  •  
  • Hands-On TCP/IP Network Services adds the final element needed to achieve a comprehensive understanding of the TCP/IP protocol suite. In two days we explain and build the network services that make a TCP/IP network practical and convenient to use, including:
    •  Name Resolution: Domain Name Service (DNS) and Host Tables
    •  Dynamic Host Configuration Protocol (DHCP)
    •  Simple Network Management Protocol (SNMP)
    •  Border Gateway Protocol (BGP) (time permitting)

    Cisco routers are intrinsic to this class, and being able to navigate within the machine is a prerequisite. We install and configure a (D)DNS server and set routers and workstations to interrogate the server when needed. Similarly, we install DHCP and show how to automatically allocate IP addresses and pass DHCP over a routed network. Since SNMP is the de facto network management standard, we configure all machines for full SNMP operability. Time permitting, we explain and connect different autonomous systems together using the Border Gateway Protocol.
