I am trying to configure a MLPPP connection using 2 VWIC2-2MFT-G703 cards. The connection comes up and runs fine but bounces every few days or so. It loks to me like there may be a clocking issue. Does the VWIC2-2MFT-G703 cards support a clock source for each port in data mode or does it only supposrt 1 clock source. If it only supposrts 1 how do I make this work for he client
