In an unchannelized J2/E3/T3 line card, the S/UNI-JET directly connects to one PM7366
FREEDM-8 HDLC controller. Each FREEDM-8 can process two high-speed links such as T3 and
E3, or can process up to eight lower speed links such as J2. The S/UNI-JET gaps all the overhead
bits so that only the payload data is passed to and from FREEDM-8. On the line side, the S/UNI-
JET is connected to one J2/E3/T3 line interface unit. On the system side, the S/UNI-JET
interfaces with a data link device over a serial bit interface.
