LED Description

E1 Link (Active Green) Solid green (On) indicates that the end to

end E1 Link is up, signifying that the link is active. The E1

Link LED is Off when the link is down.

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.

Status Blinks yellow from one to eleven times to indicate system

status. Each pulse pattern is separated by a 2 second

“off” period. Greater pulse patterns have higher priority

(buffer saturation has greater priority than an empty MAC

table). Valid system statuses are:

1 pulse—system status is okay

2 pulses —no MAC entries in the MAC Address Table

3 pulses—Clear to Send (CTS) or Carrier Detect (DCD)

from base unit are not asserted

4 pulses—IM1/I 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

TM (Active Yellow) Solid Yellow indicates an Active Test

Mode.
