Configuring BSC Interact ive 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 sequence 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 Down .
No Response Retry Count
specifies how many times the user device will be polled (if it is not responding) before
control is passed on the next cluster (accompanied by other condition checks).
Error Retransmit 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.
Explanations of Subscriber Parameters
Sq
is a sequence number, which eases selection of a line on the screen to change. To move
to another line, press
[A] and enter the sequence number.
Local Sub
is the calling address used by the local device. A Subscriber ID (see page 10-8) must
also be configured for this address.
Remote Sub
is the called address used for calls by the local device. A Subscriber ID (see page 10-
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 Number, which is the maximum number of times an autocall will be sent.
Conn ID
is an internal connection identifier that will link the BSC port with a device configured
in the
BSC Devices file (page 10-10).
