895.0. "E1(2M) RAD ASM40 problems with RouteAbout" by HGOM19::JACKWU () Mon May 12 1997 08:10

    Hi,
    
    BAD news.
    
    I have a E1 problems of RouteAboutAccess90EW.
    
    These problems seems similar with notes 359.*, 657.* and 657.*
    
    
    As followings:
    
    +------------+  +-----------+ Leased +-----------+  +------------+
    +RouteAboutEW+--+ RAD ASM40 +--------+ RAD ASM40 +--+RouteAboutEW+
    +------------+  +-----------+ Line   +-----------+  +------------+
          PPP link  E1 (2M)              E1 (2M)        PPP link
    	        Internal Clock       Receive Clock
    
    PPP link error if we use E1(2M) speed.
    PPP link OK    if we use T1(1M) speed.
    
    If we replace the RouteAboutEW*2 with CISCO2501*2, PPP link OK even 
    we use E1(2M) or T1(1M).
    
    Can anyone explain it ?
    
    I think these are our RouteAboutEW's physical problems.
    
    NPB guys, does RouteAboutEW have any problems with 2M leased lines ?
    How can solve this problems ?
    
    Thanks and Regards.

	Did you try the fix mentioned in 657.2 (setting FCD-2 mode on the RAD)? It appears that may fix the problem.
