Applications for Xrefs There are many different uses for external references. I will describe two common applications to illustrate their range. Let’s suppose you are working on a project as an interior designer and a subcontractor to the lead architect. The architect can give you a drawing of a floor plan that is still undergoing changes. You load this file onto your hard disk, in a specially designated folder, and then Xref it into your drawing as a background— a drawing to be used as a reference to draw over. You can now proceed to lay out furniture, partitions, and so on, while the architect is still refining the floor plan. At an agreed-on time, the architect will give you a revised version of the floor plan. You will overwrite the one that you have on your computer with the latest version. You can then reload the Xref into your furniture layout drawing, and the newer version of the floor plan will now be the background. In this example, the lead architect might al...
MDF,CABINETS AND DP MAIN DISTRIBUTION FRAME (M.D.F). Frame in the exchange used for making cross connections between the incoming cables and exchange equipment. On the line side of the frame the cables terminate on protector strips. It is a connecting/testing point where incoming cable (from switch room) out-going cable to cabinet are terminated. It is of two types (i) Wall Type. (ii) Floor Type. Both sides cables are terminated systematically and join them with a wire i.e. called jumper wire. By this we can change or shift a number easily. DEFINITION OF CABINET: It is a small testing point where primary and secondary pairs are terminated. CABINET CAPACITY: Total number of primary and secondary pairs those terminated in a cabinet is called capacity of cabinet. CONSTRUCTION OF CABINET: It is an almirah made of iron and fiber. It is fixed on the stand made of bricks and cement. TYPES OF CABINETS: 1 50/100 poles mount cabinet 2 300/400 ...

You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening? 1 Hardware conflict The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device. For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not inst...
