Configuring BSC Interactive 10-7
Poll Interval Timer
specifies the time between passes through the polling list.
No Response Timer
is activated after transmission of a general poll or a data frame. On expiry, a NAK–
EOT–General Poll sequenc e is transmitted, and the No Response Retry Count is incre-
mented. The timer will be de-activated on reception of any valid frame from the line
during Link Dow n.
No Response Retry Count
specifies how many times the us er device will be polled (if it is no t responding) before
control is passed on the next cluster (accompanied by other condition checks).
Error Retrans mit Count
specifies the number of times the node will resend a block of data after the receiving
device has detected an error in that block.
NAK Retry Count
specifies the number of times the node will send a frame when the receiving device is
unable to acknowledge; that is, returns a NAK to the node.
Explanat ions of Subscriber Param et ers
Sq is a sequence number, wh ich ea ses select io n of a lin e on the scre en to change . To move

Remote Sub
is the called address used for calls by the local device. A Subscriber ID (se e page 1 0-
8) must also be configured for this address.
If the BSC port is one end of a connection to a logical X.25 port in the SmartSwitch
1800, this address must match a Subscriber ID configured for the logical port.
Atcl (Autocall) causes a BSC TPAD to automatically call its HPAD when the controller
(identified by Link Address) becomes active. This parameter has no function if the
port is an HPAD.
Rtytm is the Retry Timer, which determines the time between autocall retries.
Rty # is the Retry Num ber, which is the m aximum number of tim es an autocall will b e sent.
Conn ID
