3M Dynatel™ 965DSP Subscriber Loop Analyzer Short Course - 2 days

Intended For: Engineers and technicians

Overview: Comprehensive hands-on course modeled after the 3M Dynatel™ 965DSP factory training course.  All functions of the test set are covered and students perform a series of twenty laboratories to become familiar with the test set, analyze good and faulted pairs in cable simulators, analyze crosstalk interference from other digital loops, and perform testing on ADSL circuits.  

Note:  This course covers only the 965DSP Subscriber Loop Analyzer and NOT the 965 "Classic."  Although a few of the functions and setups in the 965 "Classic" are very similar to the 965DSP, the "Classic" has no wideband capability.

Test sets are provided but students should try to bring their own 965DSP to the course.  The 3M Far End Device (either model 1342 or 1343) is indispensable for wideband and ADSL testing.  We will have the 3M model 1342 FED II available in class but students should try to bring their own (the model 1342 or 1343 FED II may be ordered from any 3M distributor).  If students plan to use the infrared port on the 965DSP to upload test results to a PC, they should plan to bring their own laptop PC as well (but we will have PCs available for this purpose).  Click here for information on how to obtain the necessary software and hardware.

A comprehensive set of course manuals is provided to each student.  One manual contains all procedures, tables and illustrations used in the presentations and labs and a second manual contains reference procedures, flow charts, tabulated cable pair and operational data and illustrations for field use.  Also included are handouts describing FED applications and use, a paper on ADSL deployment problems and an HDSL/HDSL2/HDSL4 deployment guide.  We also have permission from 3M to pass out free copies of the "3M Dynatel™ Training DVD," which contains high-quality how-to-use videos of the Resistance Fault Locate (RFL) and Time Domain Reflectometer (TDR) functions of the 965DSP (both subjects are taught in the course, and the DVD is provided as a supplement).

The 965DSP hands-on course is limited to six students per session and normally is delivered in Anchorage, AK; however, the course is portable and can be delivered anywhere in the United States (please contact us for a quote).

Prerequisite: General familiarity with modern access network systems including twisted cable pairs, POTS (Plain Old Telephone Service), Digital Subscriber Line Access Multiplexers (DSLAM), and other twisted pair digital transmission technologies and a basic knowledge of dc electricity including voltage and resistance.

Intended For: Engineers and technicians

Overview: Overview training course covering the most common applications of the Advanced Fibre Communications UMC1000A (and similar DMAX-1120) digital loop carrier system.  Emphasis is on switched and special access digital loop carrier (DLC) and Digital Cross-Connect System (DCS) applications. Students learn basic configurations and applications using fiber optic, DS1 rate and subrate DDS (dedicated digital services) interfaces.  This course includes one-half day of presentation covering general system description, installation and test overview, and craft interface overview and one-half day of hands-on provisioning work including system startup and acceptance testing.  

Students will provision of a pair of UMC1000A terminals using fiber optic transceivers and then setup POTS circuits, customer-to-customer circuits using T1 transceivers and DS-1 CSUs and using OCU-DP channel units for 56/64 kb/s connection to customer DSUs.  This course does not cover the UMC1000A in as much depth as AFC's longer factory course but it gives a good overview for people wishing to become familiar with the equipment and its capabilities.  This course will be expanded in the future to cover digital subscriber line provisioning.  This course usually is offered as a 2-day or 3-day combo with the Testing DS-1 Interfaces and UMC1000/DMAX1120 Access System Advanced short courses.

Prerequisite: Technical background and familiarity with access network equipment and ability to use a laptop or desktop PC and terminal emulator programs.

Line, Trunk & Private Line - Alignment & Testing - 3 days

Intended For: Telecommunications engineers and technicians

Overview: Comprehensive hands-on course covering switched analog lines and trunks and analog special access lines. Students learn about industry performance standards and requirements and to use voice frequency signaling and transmission test sets in a realistic environment. Laboratories include a central office switching system with analog and digital trunking and analog lines plus a variety of transmission systems and analog signaling interfaces. Although analog trunk interfaces are covered in the presentation portion of this course, the labs do not presently cover them because they are largely obsolete; however, students can work with these types of interfaces if they desire.  Private line laboratories focus on analog voiceband channels with Data Station Terminations (DST).  Students will use common switched loop testing equipment to test switched loops from the NID and then will align and test an analog special access circuit according to ANSI T1.512 requirements using the Ameritec AM5-XT and AM48 and similar VF test equipment.  This course does not cover digital subscriber lines but, since DSL loop qualification presently uses analog techniques, the principles learned will apply to that technology as well.  This course normally is given in conjunction with the Testing DS-1 Interfaces short course so students learn both analog and digital testing techniques.

Prerequisite: Technical background, experience using electronic test equipment and general familiarization with the modern access network including twisted cable pairs.
