This idea came from the municipal water departments who had originally devised a series of C-codes for water pipes and activities. For cables containing multiple groups of 25 pairs, each group will be identified by a color coded binder following the above color chart. Those phones are no longer around, but many of their small gray or beige power supply transformers still are. This method involves using 10 basic Core Construction: Solid, annealed copper; size 19 AWG Just like water pipes, these phone C-codes can in some cases be related to the type of material, but their main purpose is to identify the actual use of the cable, such as an aerial cable running pole to pole. the plug. (**) When a PIC cable is abandoned, the last letter is sometimes changed on the prints to an X indicating that it is no longer in use, such as BKTX. Neither of these two sides of the line has a connection to the local ground. Fiber Optic Cable And Connector Color Codes. cables (violet/slate binders are never used; 25 pairs x 24 units = 600 pair) to PIC cables are the only phone cables that have plastic insulated conductors, though you would typically never see the exposed interior of a lead or paper cable anyway. At various points the air hose will connect into the cable. Generally, the phone company connects the telephone lines at their termination block in a specific order. 100 pair cat3 telephone bulk cable bulk color coded telephon. colors and combining them in a logical sequence to make 25 unique pair cable telephone pair 200 callosum corpus. When used for plain old telephone service (POTS), the first wire is known as the tip or A-leg (U.K.) conductor, and is usually connected to the positive side of a direct current (DC) circuit, while the second wire is known as the ring lead or B-leg (U.K.), and is connected to the negative side of the circuit.
