Abstract :
A basic framework is given for performance comparisons of several frame detection schemes used to identify individual channels within a DS1 digital transmission system in either the superframe (SF) or extended superframe (ESF) format. Key criteria include mean misframe times, out-of-frame detection times, reframe times, tolerance to error bursts and application considerations. Through the use of Markov chain models, analytical solutions for the mean misframe and out-of-frame detection times are derived in terms of the bit error ratio and frame period. Performance comparisons of several frame detection schemes in various error conditions are made
