CHAPTER 6: Operation
3 pulses =
Clear to Send (CTS) or Carrier Detect (DCD) from base
unit are not asserted
4 pulses =
Line Driver buffer is saturated
5 pulses =
WAN receive frame(s) too large
6 pulses =
WAN receive frame(s) not octet aligned
7 pulses =
WAN receive frame(s) aborted
8 pulses =
Detected WAN receive frame(s) with CRC
9 pulses =
Detected LAN receive frame(s) too large
10 pulses =
Detected LAN receive frame(s) not octet aligned
11 pulses =
Detected LAN receive frame(s) with bad CRC
• 10BT Link: (active green) Solid green indicates that the 10BASE-T Ethernet
interface has detected a valid SQE heartbeat, signifying a valid 10BASE-T
connection.
• NS: (active red) Solid red indicates that the Digital Signal Processors (DSPs)
are not linked.
• ER: (active red) Flashing red indicates CRC Errors on the DSL (Framer) side if
the DSL Link is active or if bit errors are received during loop/BER test.
ER flashes once to indicate a CRC error (during normal operation) or bit
errors (during remote loopback 511/511E tests).
• TM: (active yellow) Solid yellow indicates an active test mode. The unit may be
placed in test mode by the local user or by the remote user.
