6525PLUS Network | A 6525PLUS is a multifunction/multiprotocol packet assembler/disassembler (PAD)  | |||||
Concentrator | and X.25 switch. If your node is based on the 6525, you can:  | 
  | ||||
  | 
  | 
  | • Have up to nine 6525PLUS processor cards in a node.  | 
  | ||
  | 
  | 
  | • Have a maximum number of 54 ports per node (combination of processor  | |||
  | 
  | 
  | cards, AIO, or UIO cards).  | 
  | 
  | |
  | 
  | 
  | • Have a maximum number of 54 network ports per node.  | 
  | ||
  | 
  | 
  | • Have a maximum number of 53 DTE ports per node.  | 
  | ||
  | 
  | 
  | • Configure any or all ports as X.25, MUX, or PAD ports because the 6525PLUS  | |||
  | 
  | 
  | allows switching on all six ports. Optionally, you can configure ports to  | |||
  | 
  | 
  | operate with synchronous protocols (SDLC, BSC2780/3270, and so on).  | |||

A 6500PLUS node contains only one type of processor card. For example, a single  | ||||||
Configurations | node may include up to nine 6525PLUS processor cards, but it cannot contain a mix of  | |||||
  | 
  | 6525PLUS and 6507PLUS processor cards. The following table shows the port  | ||||
  | 
  | configurations available for the different processor cards.  |
