  routed according to design rules. Too ambitious
  for form factor.

19
Implementation January 2001

• Response
• Simplify designs by building cards with
  functionality limited to specific site.
• Short term
• Build a SIB1 or SIBling with functionality only
  required for VRC (to be used later in ETG)
• Supplement this with increased ethernet
  capabilities. 100Hz
• Long term
• Stage upgrade by building SIB2 and SIB3 which are
  more specifically targeted to SB, L3Nodes, ETG
  and final VRC.
• Current Status
• SIB1
• At vendor, 20 bare boards to be shipped between
  Thursday and Tuesday
• Assembled, at Brown 2/22
• VBDi
