Description: Specific information that's related to the HDSL alarms, each bit in the two bytes value has the following meaning if set:

Bit 0 : Local Loss of Signal on DS1 line (HiGain only). 1 : Remote Loss of Signal on DS1 list (HiGain only). 2 - 7 : reserved. 8 : Loss of Sync word on LOOP 1 of the local line unit. 9 : Loss of Sync word on LOOP 2 of the local line unit. 10 : Loss of Sync word on LOOP 1 of the first doubler. 11 : Loss of sync word on LOOP 2 of the first doubler. 12 : Loss of Sync word on LOOP 1 of the second doubler. 13 : Loss of sync word on LOOP 2 of the second doubler.

What is ctWanHDSLAlarmsBackplane?

A bitmask of currently active HDSL-related alarms: local or remote DS1 loss of signal (HiGain only), and loss of sync word on LOOP 1 or LOOP 2 of the local unit or of either doubler -- an admin reads this to see, at a glance, which specific point on the span has lost sync right now.
