RR Timer
This is a standard LAPB/LAPD “Receiver Ready” timer. The default value is 10,000ms (10
seconds) and it should not normally be necessary to change this.
T1 timer
This is a standard LAPB timer. The default value is 1000 milliseconds (1 second) and under
normal circumstances, it should not be necessary to change it.
T200 timer
This is the standard LAPB re-transmit timer. The default value is 1000 milliseconds (1
second) and under normal circumstances, it should not be necessary to change it.
Window Size
This parameter is used to set the X.25 window size. The value range is from 1 to 7 with the
default being 7.
Disconnect link if there has been no activity for x seconds
This parameter may be used to specify the length of time (in seconds) before the link is
disconnected if there has been no activity. If this parameter is zero or not specified, then
the inactivity timer is disabled. It is useful to set this to a short period of time (say 120
seconds) when an LAPB instance is being used over ISDN. This timer can be used as a
backup hang-up timer thus saving ISDN call charges. When LAPB is being used on a
synchronous port, this parameter should normally be set to 0.

SSP (WAN) Parameters
Virtual MAC Address
Virtual MAC address. The host uses MAC addresses and SAP values as the addressing values
to discriminate between circuits (in much the same way as an IP address & TCP port define
an addressing point for a TCP socket). This is the MAC address that is reported as part of
the DLSw protocol.
Virtual MAC Address of Peer
The Virtual MAC address of the peer.
IP address of the Peer DLSw unit
The IP address of the peer DLSw unit.
Listen on Port
The read IP port. The TCP socket SNAIP listens on.
Use Port x if this unit starts the DLSw protocol
The write IP port. This TCP socket will be opened by the unit if it needs to start the DLSw
protocol.
Use interface for source IP address
Setting this parameter to a “PPP” or “ETH” instance will cause the source address used by
this SNAIP instance to match that of the Ethernet or PPP interface specified.
Close TCP connection if it is idle for x secs
This specifies the maximum period of inactivity (in seconds) that may occur before an open
TCP/ IP socket is closed. The default value is 300 seconds (5 minutes) and should not
normally require altering.
DLSw Ver
This parameter controls the DLSw version to be used. Set to 0 (default) for version 1, set to
2 for version 2.
