VOIR SS7 Network Architecture

• There are 5 adjacent points from 5 different
  2G/3G operators
• Each operator will give us a point code, and the
  values of these point codes should be different
• There will be 5 E1 lines from these 5 operators
  into our system, and each E1 will have a SS7 link
  along with 30 voice channels.
• 2 E1 lines will be connected to two E1 connectors
  on the first SPCI4.
• 2 E1 lines will be connected to two E1 connectors
  on the second SPCI4.
• 1 E1 line will be connected to 1 E1 connector on
  the third SPCI4.
• For each E1 line from one of the operators, the
  timeslots carrying voice will be output from a
  PCM port located on the same SPCI4 to the voice
  card
• How can I configure our system, including
  hardware and software configurations, to fulfill
  this network requirement?
• Idea 3 SPCI4 cards, each of which has an MTP3
  license button, and let ISUP module run on the
  host
