Number Terminal Message Port Description Severity
42 WIRE MODE NOT
COMP
SHDSL Mismatch between line interface types (2/4-wire)
between local and remote units
Major
43 SPAN IS NOT FULL SHDSL Distance between adjacent repeaters is too long.
You can identify the problematic segment by
checking the Port Status screen. In the Number of
Repeaters line, it displays the last repeater
identified by ASMi-52. This means that the
distance between the last detected repeater and
the next repeater exceeds it maximum range.
Major
44 LOOP ATTN. OVER
NETWORK SIDE
SHDSL Loop attenuation at the network side of the
repeater has exceeded the alarm threshold
Minor
45 LOOP ATTN. OVER
CUSTOMER SIDE
SHDSL Loop attenuation at the customer side of the
repeater has exceeded the alarm threshold
Minor
46 SNR MARGIN OVER
NETWORK SIDE
SHDSL Signal-to-noise margin at the network side of the
repeater has exceeded the alarm threshold
Minor
47 SNR MARGIN OVER
CUSTOMER SIDE
SHDSL Signal-to-noise margin at the customer side of the
repeater has exceeded the alarm threshold
Minor
48 LOSW FAILURE OVER
NETWORK SIDE
SHDSL Loss of Sync Word is detected at the network
side of the repeater
Minor
49 LOSW FAILURE OVER
CUSTOMER SIDE
SHDSL Loss of Sync Word is detected at the customer
side of the repeater
Minor
50 LINE PARAMERS NOT
COMP
SHDSL Modems fail to synchronize due to the
configuration parameters mismatch. For example:
• The modems operate in the adaptive mode
(Line Prob is set to Adaptive Rate) and
distance between them exceeds the
maximum range.
• ASMi-52 with V.35 interface operates
opposite remote unit with 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.
