Make sure the data bits and parity settings will match
throughout the connection.
DCE Cable Attached
determines whether the RS-232 connector pin assignments in the port-level graphics-
mode status display will be shown as DCE or DTE.
Mask Link Alarms
determines whether an alarm (see Chapter 21 ) will be generated if the link goes up or
down. If
Mask Link Alarms
is
Y
, these alarms will not be generated.
Disable X.121 User Calls
will (if
Y
) cause the port to accept only those calls that substitute an
abbreviated address (described on page 13-19) for the called address.
PVC?
identifies whether this port will be one end of a PVC (async to async or async to X.25).
If
Y
, A PVC Connection record (described on page 13-20) must also be configured.
X.25 Parameters
Default Window Size
will be assigned to an incoming call setup packet if the packet does not include a
window size (the number of unacknowledged data packets allowed per connection).
Default Packet Size
will be assigned to an incoming call setup packet if the packet does not include a
packet size.
Local Charging Prevention
if
Y
is selected for this parameter, no calls can be charged to this port. Incoming calls
from the network with Reverse Charging specified will be rejected; outgoing calls will
have Reverse Charging inserted by the network if it is not already in the call packet.
Generate M-bit Packets
is used by the PAD to turn on the M-bit in the X.25 data packet if more than one packet
is required to transmit the data from the PAD.

Autocall Options
Autocall
causes (when enabled) the PAD to automatically call the remote device (Called
Address) when the link comes up (either through rebooting the node or pressing
[F7]
after changing
Autocall
to
Y
).
Autocall Delay
causes a delay after the link comes up before a Call Request will be issued.
