Enable ENQ Char:
When this parameter is set to “On”, when an incoming call on LAPB is switched and the unit
connects to it, the X.25 switch sends a data packet on the LAPB X.25 SVC containing the
ENQ character.
LAPB 0 Default Packet Size: 128 256 512 1024
This is the default packet size for calls being switched onto LAPB 0. The default packet size
is 128, other possible values are 256, 512 or 1024 bytes.
LAPB 0 Default Window Size: 2 1 3 4 5 6 7
This is the default window size for calls being switched onto LAPB 0. The default window size
is 2, the valid range is 1 to 7.
LAPB 1 Default Packet Size: 128 256 512 1024
This is the default packet size for calls being switched onto LAPB 1. The default packet size
is 128, other possible values are 256, 512 or 1024 bytes.
LAPB 1 Default Window Size: 2 1 3 4 5 6 7
This is the default window size for calls being switched onto LAPB 1. The default window size
is 2, the valid range is 1 to 7.
LAPB 2 Default Packet Size: 128 256 512 1024
This is the default packet size for calls being switched onto LAPB 2. The default packet size
is 128, other possible values are 256, 512 or 1024 bytes.
LAPB 2 Default Window Size: 2 1 3 4 5 6 7
This is the default window size for calls being switched onto LAPB 2. The default window size
is 2, the valid range is 1 to 7.
IP Stream / XOT Parameters
IP Stream or XOT Remote IP Address:
For calls being switched in the direction of XOT, this parameter specifies the destination IP
address to be used for the outgoing XOT call. This is also used as the destination IP address
in the IP/UDP stream modes.
IP Stream or XOT Backup IP Address:
If the Switch from XOT to parameter is set to “XOT”, this is the IP address that the XOT call
will be switched to, in the event the original XOT IP address is unavailable.
IP Stream Port:
This parameter determines the IP port number used when IP stream or UDP stream are
selected as the parameter for any of the Switch from or Backup from parameters.
Note:
The XOT remote IP address and IP stream port parameters will be overridden by the values
in the NUA/NUI to IP addresses table if the call matches any entry in that table.
IP Length Header: Off On 8583 Ascii 4 byte On(inclusive)
When IP length header is “On”, a length indicator field is inserted at the start of each
packet. When set to “8583 Ascii 4 byte”, the IP length header will conform to the ISO 8583
format.
Source IP address interface: Auto Ethernet PPP
The default value for this parameter is “Auto”, which means that the source IP address of an
outgoing XOT connection on an un-NATed W-WAN link is the address of the PPP interface
assigned to W-WAN. This is because the XOT connection is initiated (automatically) within
the router and so does not originate from the local subnet (LAN segment to which the unit is
attached via the Ethernet interface).
