TL;DR: An approximate analysis of the chaining operation in a loop system is offered to display the relationships between the arrival processes, the channel allocation, and the response of the system.
Abstract: This paper offers an approximate analysis of the chaining operation in a loop system. The system consists of a central processor and N terminals linked by a common communication channel. Chaining refers to the service protocol whereby the channel is assigned in sequence to each of the terminals. Messages from terminals to the central processor are sent as chains of segments. The object of the analysis is to display the relationships between the arrival processes, the channel allocation, and the response of the system.

TL;DR: It can be shown that the suppression of upper channel interference needs little extra effort, if any, in the receiver, but calls for special care in designing the VSB filter response at the transmitter (or headend modulator).
Abstract: TV receiver and transmitter characteristics required for the elimination of visible adjacent channel interference effects are discussed. The interference mechanisms involved are explained. Effects caused by the upper adjacent channel signal are different in nature from those of a lower adjacent channel signal. It can be shown that the suppression of upper channel interference needs little extra effort, if any, in the receiver, but calls for special care in designing the VSB filter response at the transmitter (or headend modulator). To eliminate interference from the lower adjacent channel, however, the receiver selectivity has to meet requirements which are more stringent than those for the upper adjacent channel.
