Is it possible to request retransmission via L1 Multicast Line?

Is it possible to request retransmission via L1 Multicast Line?
Category : 

Answer

Users cannot request retransmission via L1 Multicast Line, because all packets sent from users are discarded at the edge switch. To send retransmission request, please use Retransmission Line (CJR) or other Internal Connections (CJU, CJM and CJW line) in JPX Co-Location.
