Speed reduced due to interleaving

Hi guys and girls wonder if anybody can shed some light on this 33 days ago I had interleaving applied to my line which reduced my speed to 44207 from around 48500. I am using a billion 8800axl apart from the SNR being reduced I can't see any reason why DLM should not of removed interleaving.Theres the stats from the modem
