Ack Count
The number of acknowledged incoming frames to be received before the
dynamic window is incremented. The value can range from 1 to 127.
This parameter is available only for LAN connections and should be modified
only for complex networks that are having problems with IBM Token Ring
bridge products. For more information, refer to Appendix D, “IBM Token Ring
Concepts.”
Window Increment
The size of the dynamic window after the number of incoming frames
specified by the Ack Count parameter has been received. The value can range
from 1 to 127.
This parameter is available only for LAN connections and should be modified
only for complex networks that are having problems with IBM Token Ring
bridge products. For more information, refer to Appendix D, “IBM Token Ring
Concepts.”
Transfer Mode
The SDLC protocol. The value can be TWA or TWS. Select TWA (two-way
alternating) for half-duplex transmission. Select TWS (two-way simultaneous)
for full-duplex transmission. The default is TWA.
The setting of this parameter is passed to the peer during XID negotiation. This
parameter is available only for SDLC connections and QLLC connections.
Station Address
A 2-digit hexadecimal string representing the SDLC station address. This
parameter is available only for SDLC connections and QLLC connections.
Role
The local link station role over the data link connection. The value can be
Primary, Secondary, or Negotiable. The default is Secondary. If you select
Negotiable, the link station role is determined by an XID exchange. When
connecting to a 37xx communications controller, select either Negotiable or
Secondary, since the 37xx has to be primary. This parameter is available only
for SDLC and QLLC connections.
