Abstract
Working DS3/STS interface cards (18, 46) receive DS3 traffic on incoming DS3 communication lines (12, 42). The interface cards (18, 46) are operable to translate the DS3 signals into STS signals, and to 'stuff' them into 'A' and 'B' clock frames provided to them by an 'A' formatter (70) and a 'B' formatter (74). These clock frames are then used to transmit data to the 'A' formatter (70) and the 'B' formatter (74). The DS3/STS interface cards (18,46) inspect incoming STS signals on 'A' and 'B' buses (82, 84) without having to switch to the inspected signal. Formatters 70 and 74 translate the STS data into formatted data, which eventually are transmitted in optical form on respective optical fibers (150, 190) at clock rates which do not have to be the same. Regeneration input and output ports ( 210, 216, 206, 166) allow the through-communication of telecommunications signals in STS format, obviating the need for down-translation to DS3 format and back-translation to STS format.
