TS insufficient alarm at MD5500
- Used toolbox to analyze the traffic at ONU.
- Took traces w.r.t to telno. and V5 id.
- No problem found in V5.2.
- Checked the ts status using dynamic view of timeslot for PV4 card at the ONU and found timeslots were almost fully occupied at busy hours.
- Added one more E1 to ONU and observed the traffic, problem was resolved and had enough timeslots available for subscribers.
E1s assigned to ONU are not as per subscriber load and all E1 Timeslots occupied soon in peak load hours.
- Project Erlang calculation should be calculated specifically for each ONU as per expected subscriber load instead of full network.
