9-10 SmartSwitch 1800 4. 0 User G uide, Rev 01
Disable Request Disconnect
prevents (if enabled) the HPAD from sending a Disconnect Request to the host if the
HPAD–TPAD connection is broken.
LPDA Support
specifies the version (if any) of Link Problem Determination Aid that can be used by
a host program (e.g., NetView or VTAM) or controller program (e.g., NCP) to test
status and to control the line and remote interface. Configurable values are:
0 (None),
1 (Version 1), and 2 (Version 2).
Idle Fill Character
specifies a character that will be inserted into the stream when the SNA link is idle.
Inactivity Timer
determines how long the SmartSwitch 1800 will wait with no activity on the HPAD
port before it will declare the port down.
L1-Duplex
determines level-1 signal operation on RS-232 ports. If Full , RTS, CTS, DCD are
always high (and are raised by the appropriate side). If Half :
●
When the DTE is ready to transmit, it asserts RTS, waits for CTS to become
high, then starts transmitting. When transmission is finished, the DTE drops
RTS (and the DCE should drop CTS). DCD is low during this period.
●
When the DCE is ready to transmit, it checks to see that RTS and CTS are not
high, then it raises DCD and starts transmitting. When transmission is done, the
DCE drops DCD. RTS and CTS are low during this period.
For both Full and Half L1-Duplex, the DTE raises DTR and the DCE raises
DSR. The link is considered up when both DTR and DSR are high.
Make sure this parameter is configured correectly, or the PU will
not become active.
PU Subscriber Parameters
PU Name
identifies the PU to an SNMP or NetView host.
identifies the PU to an SNMP or NetView host.
Local Subscriber ID
identifies the local device. A Subscriber ID record (see page 9-14) must also be con-
figured for this ID.
Remote Subscriber ID
identifies the remote device. A Subscriber ID record (see page 9-14) must also be con-
figured for this ID.
If the PU is one end of a connection to a logical X.25 port in the SmartSwitch, this
address must match a Subscriber ID configured for the logical port.
