permissible length

It is thus by no means surprising that a contentious current issue in British schools is the permissible length of boys' hair.

Since stranded cable has higher attenuation than solid cable, exceeding 10 metres of patch cabling will reduce the permissible length of horizontal cable.

Equally, if the access road is a cul-de-sac the design guide may provide for a maximum permissible length of up to, say, 300 m or a limit on the number of dwellings using the road.

The maximum permissible length of cable separating the master and slave is a function of data signalling rate and is influenced by the tolerable signal distortion, the amount of longitudinally coupled noise and ground potential differences introduced between the master and the slave circuit.

A second distinction between the two telephones is this: With the Bell apparatus the very weak electric impulses generated by the vibration of the transmitting diaphragm pass over the entire line to the receiving end, and in consequence the permissible length of line is limited to a few miles under ideal conditions.
