6500
PLUS
Processor Cards
Introduction The 6500 PLUS processor card provides the main processing power in a 6500 PLUS
node. There are three types of processor cards:
• 6505 PLUS Asynchronous Access Server
• 6507 PLUS Multifunctional Access Server
• 6525 PLUS Network Concentrator
Description 6500 PLUS processor cards are shipped with Single Inline Memory Modules (SIMMs)
in sockets U79 and U80. The processor card cannot operate without SIMMs.
Each processor card has six ports. You can password protect all ports on the
6505
PLUS and 6507 PLUS cards and all asynchronous ports on the 6525 PLUS . You can
also configure processor cards from a locally or remotely connected terminal.
6505 PLUS
Asynchronous
Access Server
The 6505 PLUS is an asynchronous packet assembler/disassembler (PAD). If your node
is based on the 6505 PLUS processor card, you can:
• Use only one 6505 PLUS processor card in each node.
• Increase the maximum number of ports to 24 by adding up to three
asynchronous I/O (AIO) cards.
• Have only two network ports per node; these must be Ports 1 and 2 of the
processor card.
• Have a maximum number of 23 DTE ports per node.
Note
You can use UIO cards in 6505 PLUS nodes if the UIO is configured only for PAD
ports.
6507 PLUS
Multifunctional
Access Server
The 6507 PLUS is a multifunction/multiprotocol packet assembler/disassembler
(PAD). If your node is based on the 6507 PLUS processor card, you can:
• Have up to two 6507 PLUS processor cards in each node.
• Have a maximum number of 24 ports per node (combination of processor
cards, AIO, or UIO cards).
• Have a maximum number of 4 network ports per node.
• Have a maximum number of 23 DTE ports per node.
• Optionally, configure ports to operate with network protocols (Frame Relay,
MX.25, XDLC), or with synchronous protocols (BSC 3270, BSC 2780,
SDLC). Any port can be configured as an asynchronous PAD port or to
operate with optional synchronous protocols.
