1 Overview
Release notes for the TT6120 TSP. This document is aimed to give a brief
explanation of additional features and bug fixes that have been applied to the
TT6120. An overview of each feature or bug fix is described along with the version
where it was first introduced.
2 How to Install this Software
2.1 Read This First!
CAUTION…
Upgrading a product will interrupt its normal operation. Ensure that the unit is not in use before commencing any upgrade
operation.
Before starting, ensure that the programming procedure is well understood.
2.2 Hardware Requirements
The TT6120 software can be upgraded using a standard RS232 cable and a PC with
a COM port available. The PC needs to have a simple terminal software e.g.
Hyperterm, ProCom Plus or any other program with support for 1K Xmodem file
transfer installed.
2.3 Communication Parameters
The following parameters are default on TT6120. (Note: These parameters can be
altered in the menu system. Setup->Advanced->RS232 Setup->Remote)
Bitrate: 115200 bits/sec
Data Bits: 8
Parity: None
Stop bits: 1
Flow Control: None
The most efficient download is achieved using the 1K Xmodem protocol.
Note that the TT6120 must be in ‘Local’ mode during download.
2.4 Procedure
Connect a PC running HyperTerm or equivalent to the TT6120’s RS232 Remote
connector using a standard RS232 cable (female in both ends). The terminal
program needs to be configured with the parameters listed in chapter 2.1. Check
that the F006> prompt appears when pressing enter on the PC.
Enter the command reset and press and hold enter until the 7100=> is displayed.
Enter the command do and press enter. The TT6120 is now waiting to receive new
software.
Using the PC software, download the f006_xxxx.ima file containing the new
software. In Hyperterm this is done by entering the transfer menu, selecting 1K
Xmodem and then giving the path to the file to be downloaded.
When the download is complete, the TT6120 will automatically re-boot and
activate the new software. The version of the active software can be inspected in
the Properties menu.
3 Changes in This Release (5.2.2)
The changes listed here are compared to the previously released software. This
release will be used in production.
3.1 Additional Features
There are no additional features in this release.
3.2 Faults Corrected
3.2.1 ATM AAL1 Input Alarms
There was an issue which occurred when an ATM AAL1 card was used in receive
mode with v5.2.0 MMI software which caused the alarm module to ignore any
changes in card status. This arose as a result of functionality changes that were
not picked up under test.
3.2.2 Drop ATM connection when ASI MPEG sync is lost
This changes the functionality of the added feature from version 5.2.0. If there
is an ATM output card in use and the input is removed causing sync loss, the
byte clock on the ATM output is set to 0. This stops any framing and will cause
downstream switches etc to go into fail. The output will restart when on re-sync
or unit power cycle.
There are one or two ‘features’ with the change:
1. When the option is switched from ‘Off’ to ‘On’, there will be a glitch in the
output. This has always been a feature when changing options for the ATM
card, but will be exacerbated because the output will be switched off. This
should not be a huge issue, as it will only occur at setup time.
2. Only works with 45MBit DS3. (Card 7311, G008). Output card must have
software version 2.001 (or 1.063 or greater if pre-V2). Input card version is
not important. The menu option to enable/disable this feature will only be
available if compatible software is found on the card. A message is printed
at the debug prompt if this is not the case.
This functionality was originally added on customer request and subsequently
changed once their requirements were made clear.
3.3 Known Remaining Issues
As with Version 5.2.0.
4 Changes in Previous Releases
4.1 Changes in This Release (5.2.0)
The changes listed here are compared to the previously released software. This
release will be used in production.
4.1.1 Additional Features
Drop ATM connection when ASI MPEG sync is lost
If there is an ATM output card in use and the ASI input is removed causing sync
loss, the output VPI and VCI are set to 0, 0 in order to drop the current
connection. They are reset to the correct values on re-sync or unit power cycle.
This functionality was added on customer request.
Privilege keys via RS232
Functionality to set and retrieve privilege keys via RS232 has been added. This is
to facilitate the use of an upgrade wizard that will accompany the next release and
all following. These commands can be accessed when in expert mode.
4.1.2 Faults Corrected
AC-3 components are incorrectly displayed
In DVB mode, AC-3 components were incorrectly displayed as ‘private’ in the TSP /
Services tab. This has now been corrected. Linear PCM and AAC audio and H264
Video component support has also been added.
Transparent mode
Disable the ability to filter pids in transparent mode. It is now not possible to alter
the content of the transport stream while the TT6120 is in transparent mode.
Transparent mode is disabled if an output option card is fitted to the TT6120 that
requires an upstream clock.
Turn off QAM output when ASI output selected
When the QAM modulator option card is fitted to the TT6120, the QAM modulator
output is now disabled when the TT6120 is configured for an ASI output.
Operation of unit when in Basic mode
When the TT6120 is set to ‘Basic’ licence mode, the unit appeared to have some
functionality of either ‘PID’ or ‘Service’ mode, however operation of the apparent
functionality was incorrect. The unit now has the correct functionality in each
mode, and will also default to Basic mode when defaults are applied. The problem
with the unit being forced into ATSC mode when in Basic mode has also been
corrected.
Bitrate settings when using Quadcast on the IP card
When using more than one output destination address on either the g036 or g076
IP card, the output bit rate could be set to exceed the maximum output rate of the
interface card. The number of output addresses in use is now used to calculate the
total bandwidth available, taking account of any extra overhead required. This has
only been applied for the g076 card.
4.1.3 Known Remaining Problems
Transparent Mode
Fix a problem when upgrading the software on the TT6120 while the unit is set to
transparent mode. The flash memory of the TT6120 becomes corrupted when
upgrading the software, causing operational problems with the TT6120.
The ability to set the playout rate of the service information (SI) to automatic
should be added. This will force the TT6120 to playout the SI on the output
transport stream at the same intervals as the incoming stream. The functionality
has been added, but is currently untested and unproven, hence not in this release.
Store Inverted/Non inverted IF setting
Store the Inverted / Non inverted IF output setting on the 5980 QAM card. Write
the parameter to flash memory so when the option card is reset the QAM output is
restarted in its previous mode of operation.
Service filter table
Redesign the service filter table, so that all services are displayed within the table
at all times. Currently depending on if Incoming Services Default is set to
Transmitted or Stopped, either the enabled services are displayed in the service
filter table or the disabled services are displayed. When enabling or disabling
services using the service filter table, the service has to either be created in the
table with all the relevant parameters initialised to the correct values, or the
service has be enable/disabled and then service deleted from the table. This gives
poor visibility of what the actual state of all services in the unit are set to, and also
can lead to corrupted services within the TT6120.
All services are to be displayed in the service filter table at all times with a
parameter to either enable or disable the service from the output transport stream.
PID and component filtering in service mode
Currently depending on if Incoming Services Default is set to Transmitted or
Stopped, it is possible to filter individual PID’s or components from services.
Change the TT6120 functionality to act in a consistent manner to either always
allow filtering or to always disable filtering when the unit is in service filtering
mode.
Event configuration using Cortex
When using Cortex to configure a TT6120 with an IP output card fitted the output
transport stream takes 30-60 seconds to become stable. After sending the
configuration to the TT6120 the audio is corrupted for 30-60 seconds and the
output of the IP option card plays out at 40Mbit/s instead of the desired bitrate.
ARM based QPSK card
Enable the new ARM based QPSK card to operate in the TT6120. The old QPSK
card has component obsolescence issues and therefore manufacture of this card
will shortly cease. Currently the new QPSK card is SPARP 3 only. An I2C interface
is required to be added to the option card so that it may be used with the TT6120’s
SPARP 2 interface. Will also require work on the QPSK card to add I2C drivers.
EITs are not recognised in ATSC mode
EITs are not recognised in ATSC mode; the only indication of the presence of any
EIT PIDs is their inclusion in the PID list in the Services tab (although not indicated
specifically as an EIT). This is due to the combination of lack of MGT decoding, and
that the pid can vary despite EITs being system tables. This also results in RRT
pids not being recognised.
4.2 Version 5.1.0
The changes listed here are compared to the previously released software. This
release will be used in production.
4.2.1 Additional Features
The unit’s serial number is required for licence upgrades, customers and customer
service engineers have stated that it would be useful to display the units serial
number on the front panel.
The ability to set the time of TT6120 to the TDT supplied within the transport
stream. Providing the customer with an easier way to set the ‘Unit Time’ and to
produce the generation of more accurate fault logging.
Correctly decode Mega-frame Initialisation Packets (MIP) from the transport
stream and display within the TSP ‘Tables’ and ‘Services’ windows. For use within
COFDM systems, to display MIP pids as System pids instead of un-referenced pids
when they are present in the transport stream.
Update the status panel to clearly display if the MPEG rate is displaying a bitrate
based on 188 byte packets or 204 byte MPEG packets. Where 204 byte MPEG
packets are being played out, implement the option to choose if a 188 or 204 byte
calculation is displayed. During development of the new QAM modulator option
card, a requirement for a 188 byte calculated MPEG rate for tuning to some
equipment was needed, while a 204 byte calculation was required for
interoperability with other equipment.
The ability to set the ethernet port operation on the Pro-MPEG IP Tx and Rx option
cards, to either 100 Base-T or to Auto negotiate from the web interface.
4.2.2 Faults Corrected
When the Reset Statistic Counter option is selected on the Pro-MPEG option card
interface menu, continuity count errors occur on the output transport stream. This
is caused because when the ‘Activate’ button is press on the interface web page,
all parameters for all input and output option settings are reloaded even if nothing
has been changed.
4.3 Version 5.0.1
4.3.1 Additional Features
Changed Received Packets, Lost Packets and Corrected Packet statistics on ProMPEG FEC Rx web interface to display a continuous count and not reset every time
the values were updated.
Added Statistic Reset option to Pro-MPEG FEC IP Rx card set up web page.
IP Tx Pro-MPEG driver was expanded to include, Number of Packets sent, reset for
number of packets sent and physical ethernet connection up time.
IP Rx Pro-MPEG driver was expanded to include, continuous number of IP packets
sent, continuous number of Lost packets, continuous number of Corrected packets,
amount of input buffer utilisation (expressed as a percentage) and an appropriate
reset for all of the above values. A physical ethernet connection up time
pararmeter was also added.
All of the new parameters for both TX and RX IP Pro-MPEG cards were added to
the IP MIB structure.
4.3.2 Faults Corrected
Display correct ethernet output bit rate after trying to set an illigal matrix size,
when using Pro-MPEG FEC IP Tx card.
4.4 Version 5.0.0
4.4.1 Additional Features
Integration of new Pro-MPEG FEC IP cards, g076 Tx and g077 RX. Added extra
control parameters and display parameters to support the additional functionality
of the new IP cards.
Amount of memory available has been increased. This allows a higher number of
services or pids to be processed by the TT6120.
4.4.2 Faults Corrected
Fixed several memory leaks. When services were added and dropped if all the
services were not dropped or they were not dropped in the order they were added,
not all of the memory allocated for that service was de-allocated.
Service filter table handling. The service filter table only displays either the enabled
services or the disabled services at any one time depending on how the TT6120 is
configured. It was possible to delete a service from a table without changing the
services filter state first, i.e. from enabled to disabled. This would mean that the
service was now lost from all tables and can no longer be turned on or off until the
unit has been reset.
4.5 Version 4.8.7
QAMUPC Modulator Interface
Bug fix. Stop unit output loss when communication was lost and regained by TDC.
4.6 Version 4.8.6
QAMUPC Modulator Interface
Maximum output power level of the QAMUPC modulator changed from 121dBuV to
120dBuV due to -manufacturers specification change.
Front panel bug fixed. When QAMUPC card is TDC controlled, changing from Annex
A to Annex B -or vice versa, does not update the front panel correctly. Bandwidth
menu should be
-displayed for Annex A only and Interlever depth memu for
Annex B only. Menu display does -not toggle.
4.7 Version 4.8.5
Internal release only.
4.8 Version 4.8.4
4.8.1 New features
The TT6120 TSP Software Release 4.8.4 contains bug fixes to faults logged in Test
Director under TT6000. There are no new features.
4.8.2 Faults corrected
The following faults have been rectified in this release. The Defect ID is the
reference number for the item in the Test Director Database.
Web Pages
Moved some Java script variables, and removed top. from variables in index.html
(top.update_page -> update_page).
Some versions of Internet Explorer used to give a "Permission denied" script error
the first time the page was loaded, and you had to press refresh to get the page to
load OK
Moved some Java script variables, and removed top. from variables in
index.html (top.update_page -> update_page).
Some versions of Internet Explorer used to give a "Permission denied" script error
the first time the page was loaded, and you had to press refresh to get the page to
load OK.
Remove old password if user come from a setting without password. (cgi_auth.c)
TSP tree used to check edit access on view, now it only checks for edit access un
update.(cgi_tci.c)
Web Server
Changed access check:
Now a valid password is needed (View or Edit) if the password check is
enabled.
Lowest level of edit access is same as "view".
All passwords are accepted if the Username & Password are left blank.
Transparent Mode
Improvements to the regulation algorithm.
It was possible for the previous regulation algorithm to get stuck in state
FLOW_TRACKING (1) with a output rate of 216Mbit/s.
PSI/SI Handling
Replace PMT CA descriptor with DVB stuffing descriptor if ECM is filtered and the
PMT is set to ‘Regenerate’.
Version number handling for PSI/SI/PSIP tables updated.
All tables in "transparent" mode will now be let through with version
numbers and CRC's unchanged. The repetition rate will still be updated.
The exception is the MGT table, which still is updated whenever a new table is
downloaded to the unit. This is needed because of the version number signalling in
the MGT.
ATSC VCT tables are now analyzed to retrieve service names. Correct service
names now shown in service tree. The SNMP agent has also been updated so that
TDC shows correct service names.
Service components with type 0x81 are now correctly decoded and presented as
AC-3 audio components, both in WEB interface and TDC interface.
In ATSC mode, an option has been included to retrieve the system clock from the
incoming STT tables.
Default repetition rates have been adjusted to be within the limits of the ATSC
specification (A/65B).
In Basic and PID modes, repetition rates are set to 10 times higher than indicated
in the .SIT file after the unit is rebooted.
Power cycle causes EIT, TDT & TOT Tables to disappear.
NIT version number is modified when NIT Transparent mode is selected.
G703 Interface Handling
Corrected startup bug that could result in invalid G703 configurations.
Corrected bug in WEB interface related to presentation of G.832 framing mode for
E3. Previous versions show this mode as M13 framing, an option that is not valid
for E3.
Verified difference between 4.5.0 and 4.7.0. 4.5.0 had a problem with "No
response" from G703 modules. This has been verified to be fixed with a new I2C
driver.
Fixed a bug that could cause a deadlock and inability to change input interface.
The error situation was typically caused by rapidly changing active input from DVB
ASI to G703 and vice versa.
Fixed bug that caused G703 boards to ignore global reset signal, e.g. G703 boards
were not reset correctly when TSP board was reset.
IP Interface Handling
TT6120 IP in ASI out signal loss after between 5 and 20 seconds.
IP Rx TS dropout, believed to be caused by no nulls on input triggering VBR mode.
IPNIC lower delay mode for lower bit rate operation (Restrict buffer size).
Encapsulation Mode not indicated for IP Tx interface
ATM Interface Handling
Ref. CALL 72472. The 'input rate mode' parameter for ATM AAL5 RX boards has
now been added to the menu system / web interface.
SNMP / TDC Issues
Updated variable for control of QAM modulator Spectrum Inversion. The SNMP MIB
variable now refers to the spectrum inversion of the RF output, not the IF output.
When spectrum inversion is disabled in TDC, the RF output spectrum will now be
normal.
Removed character table select character for start of service/provider name if
present.
TDC gets "no such name" snmp error when trying to set g703TxOutputRate for
TTV E3/DS3.
Other Issues
SW versions newer than 4.5.3 had problems booting with a configuration
consisting of ATM input, QAM output + the new 5780F version of the RF
upconverter. A fix has been introduced in the I2C driver that makes the
software handle the situation in a better way. If the error appears, the
software retries until it succeeds.
Note that when the error appears, the message as shown below will be
printed to the debug interface:
SYS--|WARNING: Entered NONE mode [i2cdmm_controller.c:383]
The error becomes visible when the I2C bus in the shelf is loaded with several
boards, but currently only seen when the new 5980F board is used together with
ATM input boards. This issue is really an FPGA issue that needs to be addressed in
a future software release.
