name: TTR
full_form: Time To Repair
context: by the same NE fault. One operator's effort is wasted. This type of assignment (and therefore, wasting effort) would not occur if AC1 process place alarm-A and alarm-B in the same group. When viewing large volume of alarms in AC1 groups, the operator can easily spot the small groups (or alarms not belonging to any group) that might be just important, in terms of impact to network operations, for example. TTR has two components â a) the duration between reception of alarms and identification of the NE fault causing the alarm and b) the duration of a repair action. The latter component is fixed. The AC1 can reduce the former component (see a), thus shortening TTR. Short TTR decreases OPEX. Short TTR increases customer's satisfaction.
description: Time To Repair (TTR) measures the duration between alarm reception and fault identification in a Network Element (NE), as well as the repair action duration. It's a Key Performance Indicator (KPI) for network operations, impacting Operational Expenditure (OPEX) and customer satisfaction.
explanation: TTR is explicitly defined as a metric quantifying time intervals related to alarm handling and repair actions within a network. Its impact on operational costs and customer experience aligns with the characteristics of a measurement.
