This parameter is relevant only if
Physical Port Interface
is something other than
RS-
232
and
Generate Cl ock
is
Y
.
3
0
means the parameter is not used.

If SDLC-LLC2 conversion is configured over the port,
Fast Select Acceptance
must be
Y
. Also, if the X.25 link is to an X.25 network, the network must support Fast Select as
well as call user data greater than 32 bytes.
Port Type
defines the protocol the port will support. Selecting this parameter will display a list
of valid protocols. (Protocol configuration is described in
Chapter 5
.)
Physical Port Interface
is determined by the Line Interface Card(s) and attached cables. The RLP record iden-
tifies the LIC, and only the valid interfaces will be displayed on the Port screen,
among:
RS-232, V.35, RS-449
, and
X.21
.
(RS-449 and X.21 i
nterfaces are valid if the LIC
is RS-422.)
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.
Line Speed
is the data transmission rate in bits per second, and the clock speed on a serial port
when the port is a physical DCE (i.e., the attached I/O cable is DCE). If this port is a
physical DTE, specify the line speed that matches (as closely as possible) that of the
device connected directly to the port.
