Characteristics of an External Access Equipment Operating at 2048 kbit/s Offering Synchronous Digital Access at 320 kbit/s - General Aspects of Digital Transmission Systems; Terminal Equipments Study Groups XV and XVIII; 7 pp
The timing signal for the insertion side should be derived from the 2048 kbit/s incoming
signal at the insertion side (Io); the timing signal for the extraction side should be derived from the 2048 kbit/s incoming signal at the extraction side (El).
