• Frame Relay protocol
• IPX protocol
• X.25 with more than 16 virtual circuits per line
• SDLC protocol if used to connect to more than 64 remote sites
• Communications line speeds greater than 64 Kbps and up to 2.048 Mbps for the SDLC
or Frame Relay protocols (Bisync is always limited to a maximum of 64 Kbps)
• Asynchronous communications or Asynchronous PPP line speeds greater than 115.2
Kbps
• Non-Asynchronous Communications line speeds greater than 64 Kbps and up to 640
Kbps for X.25
• No high speed communication line allowed when a feature code #2750, #2751, or
#2761 is installed under the same IOP
• V.25 Autocall cable not supported
• Select standby mode not supported
In particular, this applies when using #2745 PCI Two-Line WAN IOA or the IPX protocol (IPX
is used over LAN, ATM, or frame relay).
Rules for individual communication cards (adapters or processors) are found with an
explanation of the applicable feature description in the

,
SG24-2155.
For further considerations and sizing rules, refer to the feature descriptions of the specific
adapters or IOPs in the Model 250 chapter of the
