Building blocks

• It starts with a rack-chase - dimension 7U
• You add the mandatory cards (source and
  processor) on the front-side of Topex multiAccess
  rack on the dedicated positions (1 and 3)
• You have another two special positions
• A VoIP or 2E1 card into the position between the
  source and processor cards (slot no.2)
• In case a VoIP card is mounted in slot no.2, the
  E1 card will be added in the slot no.4
• All the cards are hot-pluggable no need for
  restart when replacing

1 Power supply card
2 VoIP or E1 card
3 PG cards
