I have a leased line internet at my office. For this i have a cisco router and a tellabs leased line modem. What is the meaning of DMA and PMA in tellabs modem? I have searched everywhere on the internet and cannot find what i am looking for... There are some times internet problems and when the net is down, the DMA and/or PMA leds are in an 'ON' state. I think the internet issue can be solved if i know what is the meaning of these LEDs. I have been through so many forums but all i have got is failure... Can anyone help me? Please help...
