Description

Severity

 

 

 

 

 

45

LOOP ATTN. OVER

SHDSL

Loop attenuation at the customer side of the

Major

 

CUSTOMER SIDE

 

repeater has exceeded the alarm threshold.

(all)

 

 

 

 

 

46

SNR MARGIN OVER

SHDSL

Signal-to-noise margin at the network side of the

Major

 

NETWORK SIDE

 

repeater has exceeded the alarm threshold.

(all)

 

 

 

 

 

47

SNR MARGIN OVER

SHDSL

Signal-to-noise margin at the customer side of the

Major

 

CUSTOMER SIDE

 

repeater has exceeded the alarm threshold

(all)

 

 

 

 

 

48

LOSW FAILURE OVER

SHDSL

Loss of Sync Word is detected at the network

Major

 

NETWORK SIDE

 

side of the repeater.

(all)

 

 

 

 

 

49

LOSW FAILURE OVER

SHDSL

Loss of Sync Word is detected at the customer

Major

 

CUSTOMER SIDE

 

side of the repeater.

(all)

 

 

 

 

 

50

LINE PARAMERS NOT

SHDSL

Modems fail to synchronize due to the

Major

 

COMP

 

configuration parameters mismatch. For example:

 

 

 

 

The modems operate in the adaptive mode

 

 

 

 

(Line Prob is set to Adaptive Rate) and the

 

 

 

 

distance between them exceeds the

 

 

 

 

maximum range.

 

 

 

 

ASMi-52 with a V.35 interface operates

 

 

 

 

opposite a remote unit with an E1 interface. If

 

 

 

 

the modem V.35 is set to the data rate which

 

 

 

 

is not supported by the remote unit, e.g.

 

 

 

 

2304 kbps, the units will not synchronize.

 

 

 

 

 

 

51

The device is in the external clock, but the clock

INTERNAL CLOCK

 

is not connected.
