Analogue Presented PAL Vision Circuits are designed for the transmission of uni-directional broadcast quality vision signals between the points specified by the Customer.

Up to three associated Analogue Presented Stereo Sound Circuits can be provided with one Vision Circuit. This facility is dependent upon the terminal equipment used.

Where the service rented is critical to the Customers' business operation, BT recommends that the Customer requests a second diverse circuit, where available. A diverse circuit may be requested either at the same time as the primary circuit or at a later date. A premium for the diverse circuit will be charged in addition to the normal tariff.
