LRE Problem with connection

[ziryababbas]

Friends,

i'm using LRE 24 ports with 575 CPE and it is working fine but the problem that is when the phone is dialing it is disconnecting the LAN connection on the PC and saying that the cable is unpluged, and it will take time to get back to normal after trying to resolve the ip from the server automatically.

i made some changes on the speed on the both PC & the switch and i made it HALf DUPLEX and i can use now both the PC & the phone at the same time without any problem but i need to confairm it any one can help me with that?

thanks

What is the speed u have set on both the pc and the switch?setting it to half duplex is fine but i want to know the speed set.Also, note that auto configuration on each LRE switch port sets the Cisco 575 LRE CPE device at the corresponding performance mode.
