ST-BUS Loopback 8 M All. If one, DSTo[0] is connected to DSTi[4], and DSTo[4] is connected
to DSTi[0]. This can be used in 8.192 Mbit/s or 2.048 Mbit/s mode. See Loopbacks section.
ST-BUS Loopback Framer 6 & 7. If one, DSTo[6] is connected to DSTi[7], and DSTo[7] is
connected to DSTi[6]. Used only in 2.048 Mb/s mode. See Loopback section for details.
ST-BUS Loopback Framer 4 & 5. If one, DSTo[4] is connected to DSTi[5], and DSTo[5] is
connected to DSTi[4]. Used only in 2.048 Mb/s mode. See Loopbacks section.
ST-BUS Loopback Framer 2 & 3. If one, DSTo[2] is connected to DSTi[3], and DSTo[3] is
connected to DSTi[2]. Used only in 2.048 Mb/s mode. See Loopbacks section.
ST-BUS Loopback Framer 0 & 1. If one, DSTo[0] is connected to DSTi[1], and DSTo[1] is
connected to DSTi[0]. Used only in 2.048 Mb/s mode. See Loopbacks section.
Remote Loopback 8 Framers. If one, TPOS[0]/TNEG[0] are connected to RPOS[4]/RNEG[4],
and TPOS[4]/TNEG[4] are connected to RPOS[0]/RNEG[0]. This is used especially for
8.192 Mbit/s mode but may also be used in 2.048 Mb/s mode. See Loopbacks section.
Remote Loopback Framer 6 & 7. If one, TPOS[6]/TNEG[6] are connected to
RPOS[7]/RNEG[7], and TPOS[7]/TNEG[7] are connected to RPOS[6]/RNEG[6]. Used only in
2.048 Mb/s mode. See Loopbacks section.
Remote Loopback Framer 4 & 5. If one, TPOS[4]/TNEG[4] are connected to
RPOS[5]/RNEG[5], and TPOS[5]/TNEG[5] are connected to RPOS[4]/RNEG[4]. Used only in
2.048 Mb/s mode. See Loopbacks section.
Remote Loopback Framer 2 & 3. If one, TPOS[2]/TNEG[2] are connected to
RPOS[3]/RNEG[3], and TPOS[3]/TNEG[3] are connected to RPOS[2]/RNEG[2]. Used only in
2.048 Mb/s mode. See Loopbacks section.
Remote Loopback Framer 0 & 1. If one, TPOS[0]/TNEG[0] are connected to
RPOS[1]/RNEG[1], and TPOS[1]/TNEG[1] are connected to RPOS[0]/RNEG[0]. Used only in
2.048 Mb/s mode. See Loopbacks section.
