FYI Brent and I have spoken with Paradigm, Naztec and Mel's. We have cameras and associated devices. Mel's
has been contacted to install one camera for the loop that is being removed. I have not received confirmation
but they could do the install tomorrow. The remaining loops should remain usable but it requires an SDLC cable
(communications between the video card and controller) that I believe Paradigm can supply and some
programming that we have not had the opportunity to utilize before. Keith Higgins with Paradigm has us on his
schedule to come out to assist but it will be Friday or Monday. Naztec is playing it safe and recommending a
separate rack and power supply but indicated the programming should be simple. I have since spoke with Jackie
Jamison who has set aside a SDLC cable at Paradigm for us to pick up ($50). We may be able to get the
detection changes going before Friday/Monday but we have to get the cable.
Cut detection puts the detector on constant call that maxes the time (15 sec.) unless limits are set or the loop is
turned off and recall used. The loop can be put back into operation after temporary repairs have been made.
Side Note : Mel's is currently working the conduit on Southwestern. Per

Dean,
We are going to need to keep the detection operational for this intersection. Per and our traffic division will
assist in keeping this system in operation.
I'm in a meeting now, but we can talk about it this afternoon.

Keith,
I have spoken with Mels electric regarding the traffic signal loops.
Johnny has spoken with Paring (sp) and they are checking their
inventory, but the situation is that I cannot saw this and jerry rig
something up so that the loops stay connected. As you know, there is
going to be excavation in this area and the loops just need to be
installed on recall. This may inconvenience some people, but it is what
has to be done in the mean time until a different solution is brought

forth.
Please help in assisting us in getting this resolved today. Every day
impacts this intersection in reaching ours and Coppell's goal in getting
this area opened back up.
Let me know what you think,
