Definitions (Nx64 interface)
ECA
Cable is not connected
DTR-OFF DTE is inactive
LOOP1
A loop is activated on the network interface in the direction of the Е1 equipment
Table 4.3 <ALARM> definitions
4.6.4.9
<AСO [GROUP ON/OFF])> Command
The <AСO> command (Alarm Cut Off) without additional parameter shows deactivated alarm
indications (LED and relays).
CO_FMM>ACO
ETH1, ETH2, ETH3, ETH4
CO_FMM>
The <ACO [GROUP ON/OFF]> command activates/deactivates a GROUP for alarm indications.
Definitions (E1 interface)
LOS-S
Loss of signal on the
Е1 side
LFA-S
Loss of frame alignment on the E1 side
AIS-S
Receiving AIS on the E1 side
AIS-R
Receiving AIS on the E1 side by a remote device
BER-S
The block error rate on the Е1 side exceeded the admissible value
LOOP1

e direction of the Е1 equipment
Definitions (Ethernet)
LOS-E
Loss of signal on the Ethernet interface
Definitions (SHDSL)
LOS
Loss of signal in SHDSL
LOSW
Loss of signal or frame alignment in SHDSL (loss wire)
SEGD
A failure in the line (segment degradation)
BER-H
The block error rate in the line is according to G.826
30%
ALB
Analogue loop back is active
SEGA
Errored data or errored frame alignment (segment alarm)
NM

LA
Loop Attenuation > LA threshold
LOOP2
A loop is activated on the line interface of a remote device in the direction of the local device
RCONF
Configuration of the remote device is not compatible with the configuration of the local device
(for example, the local device is configured to transmit Ethernet data, while the remote device
is configured to transmit two E1 streams)
