Configuring Async Pads 13-13
LICs are shown in parentheses:
3
= RS-232 (RS-232)
4
= V.25Bis_Dial (RS-232)
5
= V.35 (V.35)
6
= RS-449 (RS-422)
7
= RS-530 (RS-422)
8
= X.21 (RS-422)
Blocked Port Flag
causes the port to be enabled (
N
) or disabled (
Y
) at node IPL. The port will remain in
that state until this parameter is changed (and sent to the node) or an on-line enable/
disable is performed. (See "
Disabling and Enabling Ports" on page 18-1.)
X.3 Line Speed Code
specifies the data transmission rate in bits per second. Select the speed that corre-
sponds (as closely as possible) to the configuration of the device connected to the port.
Codes are as follows.
0
= 110
1
= 134.5
2
= 300
3
= 1200
4
= 600
5
= 75
6
= 1500
7
= 1800
8
= 200
9
= 100
10
= 50
11
= 75/1200
12
= 2400
13
= 4800
14
= 9600
15
= 19.2K
16
= 38.4K
17
= 57.6K
255
= Autobaud
The maximum speed for an RS-232 physical interface on an N7400 or
7500 is 19.2K.
Autobaud causes the FRX8000 to read the line speed of the first trans-
mission from the async device, then set that speed at the port (up to a
maximum of 57.6K bps). To specify
Autobaud
, press
[Enter]
at the
X.3 Line
Speed Code
prompt to accept the default. (Do not enter
255
; it will not be
accepted.) Also, autobaud will not work if the actual line speed of the async
device is
38.4K bps
. If this is the speed, select value
16
.
Profile Name
is an async PAD profile (described on page 13-2) that will be in effect on this port until
the async subscriber logs into the PAD (described on
page A-1 ), at which time the
profile in the Async PAD Login record (described on page 13-8) takes effect.
Login Required
determines whether or not async PAD subscribers will be required to log in before
connecting with this port. If
Y
, the async device operator must enter a subscriber ID
(specified in the Subscriber record) and password (specified in the Async PAD Login
record) to connect.
Banner Name
identifies the PAD “banner,” a string of characters sent to the async PAD port for
display on the user device when a subscriber becomes connected at level 1. It is
usually a message telling the subscriber he is now connected. The banner is defined in
a separate operation, described on
page 13-10 .
Parity:
0
= None
1
= Auto-detect
2
= Even
3
= Odd
FRX8000 8000 supports 8 data bits with no parity checking, or 7 data bits
with even or odd parity checking. It also supports 7 data bits with auto-
detect parity checking if
X.3 Line Speed
is set to
Autobaud
and PAD profile
21 is configured to check parity.
