Rel. 2.6
Extra “Going Secure” in Remote Control Mode
Applicability:
ALL
Symptom:
When establishing a call to a remote terminal, the remote terminal sees “Going Secure”
twice.
Cause(s):
It is an anomaly of the Release 1A/1B software. It should only affect users who are
developing telecommunications software scripts for automating data call establishment and file
transfer.
Resolution:
If you are writing scripts, consider that you might see two copies of some messages.
Erratic Host Data Port Operation
Applicability:
ALL
Symptom:
When performing PC file transfers, the line speed does not appear right.
Cause(s):
Many PC serial ports do not fully support EIA-530.
Resolution:
Make sure your Host Data Port option is set to RS-232.
AUTOVON/DSN Precedence Tones Incorrect
Applicability:
ALL
Symptom:
The switch does not recognize call precedence requests, or the call precedence is not
what you expected.
Cause(s):
(1) If the subscriber line is not provisioned to support call precedence, the switch will not recognize
call precedence requests.
(2) If the subscriber line is provisioned to support call precedence, a digital switch will recognize
specific characters as precedence characters, an analog switch will recognize specific DTMF Tones.
Precedence
Digital Switch Character Analog Switch DTMF Tone
Flash Override
A
697 + 1633
Flash
B
770 + 1633
Immediate
C
852 + 1633
Priority
D
941 + 1633
Dialing precedence was implemented in STE Release 1B. There are no known problems when
connected to a digital switch. However, STE Release 1B inverted the precedence/DTMF Tone
mapping (e.g., Flash Override = 941 + 1633) for analog switch connections.
Resolution:
(1) Coordinate with your serve provider to have your subscriber line provisioned for call precedence.
(2)
The Precedence/DTMF Tone mapping will be corrected in STE Release 1C. Until then, if you are
connected to an Analog Switch, use D = Flash Override, C = Flash, B = Immediate, A = Priority.
Self-Test Failure: HP 0004
Applicability:
ALL
Symptom:
The STE displays “Software Test Failure: HP: 0004”.
Cause(s):
The STE has encountered a Software Verification Error.
Resolution:
Insert Crypto Card and perform a MODE-MUTE Reset.
Case-Sensitive AT Commands
Applicability:
ALL
Symptom:
Under some conditions, a “remote dialing command” connection is established but the
connection fails to go secure.
Cause(s):
Under analysis. It appears the problem only occurs if the AT commands are in upper
case.
Resolution:
Make sure the AT commands are all in lower case.
Remote Authentication 112 or 128 KBPS data call disconnects prior to far end authorization.
Applicability:
ALL
Symptom:
A STE under Host Port Control attempting to establish a remote authentication secure
data 112 or 128 kbps call spontaneously fails then disconnects the call.
Cause(s):
STE internal ISDN resource management requires initiation of the secure data traffic flow
within 100 to 200 milliseconds of remote authentication data receipt in order to maintain ISDN B
