12-10 SmartSwitch 1800 4.0 User Guide, Rev 01
1
At line speeds of 38.4K bps or higher,
RTS/CTS H/W Flow Control
should be
Y
.
2
If
1
(Transparent Polled Async HPAD) or
2
(Transparent Polled Async TPAD), con-
figure this async port as one end of an HPAD–TPAD PVC.
3
If
Assemble Full Message
is
Y
, the remote device must be configured to generate M-bit
packets.

The
Default Calling Address
is relevant only if
Disable X.121 User Calls
is
N
.

The
Called Address
is relevant only if
Autocall
is
Y
.
Port Type
specifies the protocol the port will support. Selecting this parameter will display a list
of all serial protocols loaded in the device.
Physical Port Interface
must be configured as follows. For reference, port locations are shown on page 6-1.
●
Port 0 is always
RS-232
.
●
Port 1 is
RS-232
or
DSU
, depending on whether the optional CSU/DSU card is
installed.
●
Ports 2 and 3 are determined by the attached cables:
RS-232
,
V.35
, or
RS-449
.
Blocked Port Flag
will cause the port to be enabled (
N
) or disabled (
Y
) at node IPL. The port will remain
in that state until this parameter is changed or an on-line enable (
[B], [B], [C]
from the
Main Menu) or disable (
[B], [B], [A]
from the Main Menu) is performed.
X.3 Line Speed
is the data transmission rate in bits per second. Specify the line speed that matches (as
closely as possible) the configuration of the device connected to the port.
Selecting this item displays a list of valid line speeds. To specify a speed, press the
letter corresponding to the speeds. Valid speeds are:
50 75 75/1200 100 110
134.5 150 200 300 600
1200 1840 2400 4800 9600
19.2K 38.4K 57.6K Autobaud
Selecting
Autobaud
causes the line speed to be read from the first trans-
mission from the async device, then set automatically.
