Description: Duration of Loss of CRC Multiframe Alignment (LCMA). Counter #30 of the ATM core, only available on CES-E1-CRC interfaces.

What is adnDsx1LcmaCounter?

This counter measures the duration of loss of CRC multiframe alignment (LCMA) on E1 CRC interfaces when frame structure is broken. Engineers monitor LCMA because it prevents proper error detection across frame boundaries, allowing undetected errors to pass through to higher layers. A value of 120 seconds shows CRC multiframe alignment was lost for 2 minutes, disabling the CRC error-checking mechanism during that window.
