Rel. 2.6
11-5
channel synchronization. The far end authorization command (AT+C1) must be presented within this
time constraint to prevent internal buffer overflow conditions within the STE.
Resolution:
Use the secure data access control lists for far end authentication at the 112 kbps and
128 kbps data rates.
STE accepts dial digits but nothing happens. The call does not connect.
Applicability:
ALL
Symptom:
Using either the speakerphone or a call appearance button to go off-hook, a non-secure
(or secure) speakerphone disabled message appears followed approximately 30 seconds later by the
STE dial display. The STE accepts and displays digits dialed but the call is not connected.
Cause(s):
The TPA disabled non-secure (or secure) speakerphone operations. The STE will not
allow dial digits or audio traffic to be presented to the connected telephone network, thus the call will
not be connected.
Resolution:
Use the handset to place calls, or ask the TPA to enable the desired speakerphone
mode(s).
STE Speed Dialing Problems.
Applicability:
ALL
Symptom:
Tones stick when accessing voice mail or keypad locks up.
Cause(s):
The STE assigns a store area for a 26-character speed dial. If all 26 characters are used,
the STE does not handle all characters correctly.
Resolution:
Use less than 26 characters in speed dials.
Manual intervention required when STE resets.
Applicability:
ALL
Symptom:
If there is a power failure and a crypto card is inserted in the STE, it verifies the integrity
of the crypto card and requires the operator to acknowledge the results of the integrity check.
Cause(s):
The Government’s security policy requires that the operator Manually acknowledge the
results of the crypto card integrity check.
Resolution:
When not is use (particularly at the end of the day), remove the crypto card from the
STE. If the STE resets, the STE will be automatically restored to operational status without Manual
intervention.
