Chapter 5 Connecting to an ISP
Configuring Captive ISP on the JACE-4/5

ISP Configuration Properties
ispPrimaryNumber any valid phone number,
including any numbers used
to access an outside line and
any number of pause
characters (,)
9,5551234
The primary phone number that the JACE dials to reach the ISP.
ispBackupNumber any valid phone number,
including any numbers used
to access an outside line and
any number of pause
characters (,)
9,5551234
A secondary phone number that the JACE can dial to reach the
ISP. If the JACE fails to connect on the primary number, the
secondary number is used until it fails to connect, then the primary
one is used.
If the ISP only has a single access number, change this value to the
same value as the ispPrimary number.
ispUsername any combination of letters,
numbers and special
characters
user@isp
The user name given to you by the ISP.
ispPassword any valid password
password
The password of the user name given to you by the ISP.
ispRetryCount any integer
1
When the JACE fails to connect to the ISP, it reverts to dial-in
mode, where it waits for an incoming call. The retry count specifies
the number of failed dial attempts that occur before the JACE
switches to dial-in mode. Used in tandem with the ispRetryDelay
parameter.
ispRetryDelay any integer
2
The retry delay specifies the number of minutes that the JACE
listens for incoming calls before attempting to dial another
connection. Used in tandem with the ispRetryCount parameter.
For example, if the retry count is 3 and the retry delay is 10, the
JACE will dial the ISP 3 times (alternating between primary and
backup number) in succession. If all 3 attempts fail, it will then
revert to dial-in mode for 10 minutes before making another 3
connection attempts.
ispDisconnectTime1
ispDisconnectTime2
ispDisconnectTime3
ispDisconnectTime4
ispDisconnectTime5
ispDisconnectTime6
Note: These
parameters are not
listed in the
ras.properties file
but you can add
them when
necessary.
A set of integers in the form
hh:mm-n where
• hh is time in a 24-hour
format (0-23)
• mm is the minutes past the
hour (0-59)
• n is the disconnect duration
in minutes
For example:
ispDisconnectTime1=8:35-5
(disconnect at 8:35 a.m. and
stay disconnected for 5
minutes)
ispDisconnectTime2=0:00-60
(disconnect at midnight and
stay disconnected for 1 hour)
These parameters allow you to set up regulated disconnect times
for the modem. You can schedule up to 6 disconnects (with a
configurable duration) in a 24-hour period. When the disconnect
duration expires, the JACE automatically redials the ISP. You must
use a unique ispDisconnectTimen for each disconnect you want to
schedule.
A disconnect session may not cross midnight. If the JACE must
stay disconnected from 11:00 p.m. 1:00 a.m., you must make 2
entries, one from 11:00 pm to midnight (23:00-60) and another from
midnight to 1 am (0:00-60).
The Niagara station maintains the time of day clock for this feature.
The station handles adjustments to GMT for daylight saving times
and time zone. Therefore, if the station is not running, the
disconnect feature is disabled.
Note: If any entry contains any invalid values, it is ignored.
For release 2.3 or later, you schedule disconnects using a Niagara
object. See “Using the IspConnection Object to Control
Disconnects,” page 5-15.
