1 General
The RECL8 is an 8-channel re-clocker for 34Mbit/s G.703 HDB3 signals or 45Mbit/s DS-3 telecom
signals. RECL8 meets ITU-T G.703 for HDB3 coded signals, and the specifications of the North
American standard for plesiochronous digital hierarchy (PDH) telecommunication systems. This unit can
be used in combination with one of Triton high-bandwidth video routing switchers to create a 34Mbit/s
HDB3 router, or a 45Mbit/s DS-3 router. The RECL8 provides automatic cable equalizing and re-
clocking on all channels. High performance circuits in SMD technology assure undiminished signal
quality.
