==Errors Corrected==
=== Issue 3052: $TPROG causes AMC reset: ===
+
===Issue 3213 Reset when 7820 backup===
$TPROG L%1.d U1 is used in the standard PrisCom database when the key returns to "0" position. Fixed(X10.23(1127))<br\>
+
Backup could crash due to overuse of system resources. The backup/restore function is optimized.
=== Issue 3108: SIP trunk, short number not possible: ===
+
===Issue 3274 and 3320 IP Program distribution and mixed Multi Module with E7/E20/E26===
[[Extended_Short_Number_Usage|Short number usage]]<br\>
+
Combination of E7 / E20 / E26 program distribution will only work with prog.dist over IP.<br>
With PNCI you can use the "Phone" function to define 3- or 4 -digit short numbers for easy access to the most frequently used phone numbers. You could also do 71 transfer to short numbers. A short number should show up in the directory list of the display.<br\> Short number system for SIP is now implemented.(X10.23(1127))
+
Remember to open the RTP voip ports in AlphaWeb IP filters !
 +
===Issue 3278 Missing first digit in display when node number is 15===
 +
Low level function bug related to node numbers ending in 0x0F (HEX), 15,31,47, 63 etc.
 +
===Issue 3324 $ALRM to IP station===
 +
Assert when disconnecting $ALRM to IP stations.
 +
===Issue 3338 Time setting "785" and AlphaPro===
 +
Local time setting is now changing local time and not UTC time.
 +
===Issue 2758 Serial communication via Eth===

 +
 
 +
==Functional changes / Enhancement==
 +
===Treble preemphasis adustment of all IP audio===
 +
IP audio connections in AlphaNet are not compatible with earlier versions of AMCD SW. This is because  treble preemphasis of AlphaCom audio is now removed when converted to IP/RTP. This change is done in order to improve audio compatibility with IP stations and third party devices. When calling between AlphaCom with old and new SW, audio is connected, but the treble will be too low in one direction, and too high i the opposite direction. Beside not sounding right, the voice switched duplex failes to work properly, requiring extensive use of M-key.
 +
 
 +
===External VoIP audio gain adjustment===
 +
[[IP audio Gain adjustment]] options. Gain towards SIP devices is now by default +18db, giving more appropriate audio level towards external exquipment.
 +
===Multicast reachability test===
 +
 
 +
*IP station multicast reachability tests (mping), with reporting to syslog.
 +
*IP station not receiving RTP audio after connect, error forwarded to syslog.
 +
 
 +
===Fader support in IP only system===
 +
Use AMC-IP FPGA for [[Fader Resource]]. Allowing Groupcall and Simplex conference in "IP only" system.
 +
===Extended SIP-DTMP signaling===
 +
 
 +
*Outgoing call to SIP: DAK 2 - 5 sends DTMF signals A - D.
 +
 
 +
===Pager support for 8 Bit Ascom ESPA protocol===
 +
Support Norwegian character to paging. [[ASCOM_Norwegian_Character_Mapping | Ascom Norwegian Characters]]
 +
===OPC server license support===
 +
License for connection of OPC server supported.
 +
===Global Conference Lockup Situations===
 +
Bug fix related to global conference, node reset, default speaker conflicts and resource lockup.

===Issue 3240:Ringing group - Loose CR mode when called===
 
When in call requester mode, you can be called by anybody, which will take you out of call requester mode.  It will be confusing if you expect your call to be answered and all of a sudden somebody else gets through. There should be a mechanism that when in call requester mode you can only be called by a station which has you in the queue. This is fixed by setting the caller in busy state and use automatic call override when answering from a ringing group.

AlphaCom 10.xx Release Notes


AMC 10.31X303 (2008-03-03)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.30. 

System upgrade file:
alpha_sys_10_31x0303.tbz2

Precautions:
alpha_sys_10_00.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.


Errors Corrected

Issue 3213 Reset when 7820 backup

Backup could crash due to overuse of system resources. The backup/restore function is optimized.

Issue 3274 and 3320 IP Program distribution and mixed Multi Module with E7/E20/E26

Combination of E7 / E20 / E26 program distribution will only work with prog.dist over IP.
Remember to open the RTP voip ports in AlphaWeb IP filters !

Issue 3278 Missing first digit in display when node number is 15

Low level function bug related to node numbers ending in 0x0F (HEX), 15,31,47, 63 etc.

Issue 3324 $ALRM to IP station

Assert when disconnecting $ALRM to IP stations.

Issue 3338 Time setting "785" and AlphaPro

Local time setting is now changing local time and not UTC time.

Issue 2758 Serial communication via Eth

Using 485 multidrop protocol can cause communication errors both on serial adapters and when connected directly to the AMC serial port.

Functional changes / Enhancement

Treble preemphasis adustment of all IP audio

IP audio connections in AlphaNet are not compatible with earlier versions of AMCD SW. This is because treble preemphasis of AlphaCom audio is now removed when converted to IP/RTP. This change is done in order to improve audio compatibility with IP stations and third party devices. When calling between AlphaCom with old and new SW, audio is connected, but the treble will be too low in one direction, and too high i the opposite direction. Beside not sounding right, the voice switched duplex failes to work properly, requiring extensive use of M-key.

External VoIP audio gain adjustment

IP audio Gain adjustment options. Gain towards SIP devices is now by default +18db, giving more appropriate audio level towards external exquipment.

Multicast reachability test

  • IP station multicast reachability tests (mping), with reporting to syslog.
  • IP station not receiving RTP audio after connect, error forwarded to syslog.

Fader support in IP only system

Use AMC-IP FPGA for Fader Resource. Allowing Groupcall and Simplex conference in "IP only" system.

Extended SIP-DTMP signaling

  • Outgoing call to SIP: DAK 2 - 5 sends DTMF signals A - D.

Pager support for 8 Bit Ascom ESPA protocol

Support Norwegian character to paging. Ascom Norwegian Characters

OPC server license support

License for connection of OPC server supported.

Global Conference Lockup Situations

Bug fix related to global conference, node reset, default speaker conflicts and resource lockup.

DECT station lockup

Robust handling of call termination to avoid lockup of ATLB stations.

Improved update of Watchdog

Reset due to false watchdog timeout fixed.

AMC 10.30 (2008-01-17)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.30. 

System upgrade file:
alpha_sys_10_30.tbz2

Precautions:
alpha_sys_10_00.tbz2 must be installed.

AlphaPro 1028 or later must be used due to WACS crash caused by to large nvram size when using older versions.


Errors Corrected

Issue 3052: $TPROG causes AMC reset:

$TPROG L%1.d U1 is used in the standard PrisCom database when the key returns to "0" position. Fixed(X10.23(1127))

Issue 3108: SIP trunk, short number not possible:

Short number usage
With PNCI you can use the "Phone" function to define 3- or 4 -digit short numbers for easy access to the most frequently used phone numbers. You could also do 71 transfer to short numbers. A short number should show up in the directory list of the display.
Short number system for SIP is now implemented.(X10.23(1127)) (AlphaPro is currently (1028) not supporting the configuration)

Issue 3201 SIP stations currently used

When configuring new SIP stations the license use is now updated without the need of a reset.

Issue 3206: Serial Communication Problems (1021)

Reset of AlphaCom in relations to Serial Port use. Serial port buffer made better.(X10.23(1127))

Issue 3235: Audio Event In AlphaNet

When calling a station in a different node, event type audio and always programmed in the called node is not triggered. This was due to the move of duplex from end node to start node. The default behavior of IP AlphaNet is now back to end node duplex.(X10.23(1127))

Issue 3242: SIP RE-INVITE

SIP implementation now does support RE-INVITE(X10.23(1127))

Issue 3269 SIP rtp audio on different UDP ports

Some SIP equipment sends RTP packets from different UDP port than the one they are receiving on. This is now supported by AlphaCom.

Issue 3270 SIP Use CANCEL, not BYE

After a ringing timeout the AlphaCom terminates the call with SIP command ‘BYE’ instead ‘CANCEL’, fixed.

Issue 3277 CR notification is missing/changed

Some Issues with Call request notification after ringing group implementation fixed.

Issue 3279 Event Handler discon group call

Bleep priority 0 is now legal to use. RedBoot Fix

Issue 3268: Serial data in/out during boot

The serial data transmitted during reset is removed.

Functional changes / Enhancement

Hostname support

Hostname can be stored for SIP destinations instead of ip address.

Mutual exclusion groups increased

Mutual exclusion groups increased from 4 to 8

Number of groupcalls increased

The number of groupcalls is increased from 100 to 250 (No AlphaPro support 1028)

Local Echo Canceling

LEC
10 channels of local echo canceling are available for "open" handset conversation when using SIP, Multimodule IP and AlphaNetIP.
The channels are allocated when needed, when no more resourced switched duplex is used.

Faster synchronizing of database to flash

The speed of synchronizing the configuration database to flash after "SendAll", dak programming etc is increased.

Pocket paging "meet me" during conversation

Feature 25, Pocket paging meet me, alarm priority added to the autoload as dirno "48".

Outgoing conversation related to SIP

Private Ringing Outgoing
Event type 33, used for state of outgoing conversation to SIP.

Event handler %1.pag

New event handler operator %x.pag (x = 1 or 2) added for getting pager related to a station.

New DP command $VOL

VOL
New DP command $VOL, adjust station volume 0-9.

Restriction of syslog reporting

Syslog system and debug reports are restricted to 60 messages each hour to prevent overload because of faulty configuration or other active syslogging problems.
The limit can be adjusted from TST:

TST>>nvram - ex_profile.glob_const.syslog_block = 6 (6 = 60 messages pr hour)

Enhancement Issue 3266 Selective dialing

Short number usage
When calling in to the AlphaCom via SIP gateway, it is be possible to automatically connect to an AlphaCom feature which makes it possible to do selective dialing. If no dialing within a preset time, the call is forwarded to a predefined number. The short number configuration system is used (Currently not available in AlphaPro 1028)

Enhancement Issue 3272 SIP - DAK8, OnHold and Transfer

Transparent mode DAK configuration
Key used for activating transparent modus during SIP calls can now be change in NVRAM.

TST>>nvram - ex_profile.glob_const.trans_mode_dak = 8 (Default key is 8.)

Enhancement Issue 3275 Group call without M-key

Automatic M-key in group call
A group call can be configured to work as automatic "M-key" when initiated

TST>>nvram -  ex_profile.group[G].flags = F

G

  • group number 1 > 250

F

  • 0 = default (press M key)
  • 1 = automatic M-key from all stations
  • 2 = automatic M-key only from SIP calls.

Enhancement Issue 3304 Increase AlphaNet data links

The number of AlphaNet data links is increased from 20 to 50.

AMC 10.22 (2007-09-05)

Release: Official, available on request
/opt/amc/bin/amcd
NVRAM version 10.20. 

System upgrade file:
alpha_sys_10_22.tbz2

Precautions:
alpha_sys_10_00.tbz2 must be installed.

Errors Corrected

Issue 3149: Follow Me(72) and User/Phy number

There was a mix of user and physical number in the follow me function. Stations with different physical and user number would not have correct follow me behavior.

Issue 3157: Call Request Transfer to Phone

Call request forwarding is solved by the new feature Call request forwarding by search strings

Issue 3210: AlphaNet- CRM4 - display call request

The calling party’s number is not displayed when answering the call request (or MST mail) from a CRM IV type station in another node (AlphaNet). Only the name is shown. The error is only when the answering station has the Station Type set to "CRM 3&4" in software. Fixed.

Issue 3214: $CANM with source as global number

The $CANM can now use global number as source without adding the specific node number (use L2345 in stead of L(2)2345)

Issue 3225: IP substation: Call Req Mode - LED

If call requester mode is removed from an IP station the Audio to the IP station is now terminated.

Issue 3229: Formating of EXP not OK

Formating of %1.EXP is not working properly

Issue 3231: Statistic Log on IP station

Calls to IP stations in now logged in the SysLog statistics

Issue 3233: No Line error if Hot-line enabled

The flag ignore_st_down_in_conv allow stations to fail during conversation. For hot line station it means that if hot line is trigged during station down it will not be reported. Fixed by setting a short timeout on how long station can be down when active

Issue 3238: Hanging audio links to SIP/RMD

When initiating a call to SIP/RMD from AlphaCom and terminating during setup tone the Audio connection is not disconnected. Fixed.

Issue 3240:Ringing group - Loose CR mode when called

When in call requester mode, you can be called by anybody, which will take you out of call requester mode. It will be confusing if you expect your call to be answered and all of a sudden somebody else gets through. There should be a mechanism that when in call requester mode you can only be called by a station which has you in the queue. This is fixed by setting the caller in busy state and use automatic call override when answering from a ringing group.

Issue 3247/3252: AlphaCom uses duplex algorithm when conversation with Ring Master

The duplex algorithm is no longer used on AlphaCom side when calling/called by Ring Master.

SysLog

In some cases syslog reporting from AlphaCom was not correctly initiated.

Functional changes / Enhancement

DTMF tones during conversation

Feature for dialing DTMF tones during conversation DTMF feature (107) works for local conversation or towards SIP/RMD. Can Also be used as Data Message DTMF_CONN

Event trigger during conversation

New feature Event Trigger During Connection (108).

Parallel Ringing

Add stations in Parallel Ringing when station is in private ringing mode

Ringing Group

New behavior of call request. Private ringing tone on receiving station(s). Ringing Group (109)

  • SEND_MAIL added new flag for "auto delete" functionality and optional ringing tone in use with ringing group.
  • CANCEL_MAIL allowed LV in destination field

Global Conference

New fixes and adjustments

  • Regular interval Root of conference broadcast message was not sent in all situation. (A safety message for reconnecting if links have been down etc)
  • The interval of Root of conference broadcast message is now decreased from 1 hour to 1 minute. It means reconnecting of missing nodes and cleaning of unused links will be much faster after certain network/reset problems.
  • Useless single AlphaNet audio links to root nodes with no conference members are cleared.
  • When Root of conference is AMC 8/9 and there is an IP transit node with members of the conference, leaf IP nodes was not able to connect to the conference due to CODEC selection failure.
  • Better terminating algorithm when a conference only consist of default members (in several nodes).

HTTPS support added

Gives the possibility to access AlphaWeb over a secure connection. See AlphaWeb Technical

AlphaWeb Custom Scripting

AlphaWeb Custom Scripts lets the end user extend the AlphaWeb functionality. Typically this can be 'Click to Call' type of applications.

Intelligence added to the code receiving $SM (DP). If UDP group not specified, and mail sender is local, look up the UDP group from NVRAM. Can not be done if mail sender is in a different node. %1.udp macro added to the EventHandler, so a complete $SM can be sent in the first place.

Issue 2952: Dual Display MDF text corrections

Some display text cleanup regarding during mail sending.

Issue 3142: Line errors at startup

At startup there could be line errors reported at non existing physical numbers. Corrected

Issue 3161: Event handler %scutf, comma

AMCD Event handler: The %scutf macro now works properly when using comma as delimiter.

Issue 3163: Conversation incoming second user.

Conversation incoming [07] at B-sub (e.g.2001) which is a second user (not default) to phys. 10 (2000) does not work. The event handler is now updated so that incoming event %dir and %name reflect the actual user dialed.

Issue 3164: Call request from data protocol (from other than default user)

If you simulate by data a call request (sender e.g.2001) to CRM4 2500 the call request message is ok (sender 2001). You are able to call back (locally node2) with 70+8 or 7638 and you are connected to the default user (2000 FBSAR), but the call request message (initiated from 2001, not default) is not removed. If you call back by manual dialing 2001, the message is removed. Correct directory number (other than default user) is now used when canceling mail.

Issue 3176: SIP: Gateway blocked, reset required

Issue 3203: SIP: Handytone INFO digits ignored workaround

Workaround for problem with Grandstream Handytone 488, firmware 1.0.3.64. Ingoing call to Alphacom, then a lot of keying, for excample of * and # for simplex / groupcall keying. Then after some 10 - 20 incomming INFO messages, SIPD suddenly ignores a INFO message. This in turn locks up Grandstream, so that it does not send a BYE when the handset is replaced.

Issue 3205: Line test 7872 in multi module

The 7872 line test is now working again for Multi module AGA/AE1

Issue 3215: Busy/Private override in AlphaNet

Priority of audio resources allocation is handled by the priority of the initiator station.

Errors Corrected

Issue 2715: AlphaNet Duplex in combination with AMC 8/9:

In combination AlphaNet with AlphaCom 8 and 9 and exchanges via IP there will be a problem with delay adjustment of the duplex algorithm when calls are made from IP to an AMC 8/9 exchange.
The duplex algorithm is now run in A node when going from an ASLT station to IP AlphaNet thus avoiding duplex in end AMC 8/9 nodes.
In transit systems with certain combinations of AMC- 8/9/IP, SIP, AGA, AE1 and Multi module IP some issues could still occur that needs special configuration. (See separate duplex document).

Issue 2887/3113: SIP automatic duplex switching:

When calling SIP there can be problems with the standard duplex algorithm due to DSP echo cancelling in the SIP station. A new duplex algorithm is available for duplex towards SIP stations that is speech controlled only from volume of the microphone signal from the SIP link.

Issue 3012: Echo in SIP handset:

When talking with handset conversation between Intergard station and SIP station the SIP station will get echo in the handset due to overhearing in AlphaCom handset (and no echo cancelling). Handset to handset communication will now be forced in duplex. (Default delay setting for SIP = 30ms. Full duplex can be obtained if parameter “max_off_hook_delay” is adjusted to 40 ms or more)

Issue 3015: AlphaNet: No Camp On Busy:

There is no "camp on busy" when all AlphaNet lines are in use. Instead one gets a rejection tone. Same behaviour with AGA line, AE1 and VoIP. Feature implemented.

Precautions:
alpha_sys_10_00.tbz2 must be installed.

Functional changes

Pulse RCO:

Support for generating a pulse of specified length on a “logical” RCO.
New parameter “Duration” is added to the event handler-built-in command “RCO” and the data protocol message $SLRC. Examples, pulse RCO # 13 on for 1 second: “rco 13 on 10” or “$SLRC W13 1 w10”.
Duration is in tenths of second. If Duration parameter is present, and non-zero, the RCO state specified in previous parameter lasts for the specified time. After the time has expired, the RCO is toggled to the opposite state. If a new $SLRC/RCO on the same RCO arrives while the pulse timer is running, the timer is cancelled, and the new message determines the new RCO state. Duration = 0 means infinite duration.

DAK RCI EVENT:

New event Dak key as RCI (30). Sub event = DAK key number. ON = Dak key press, OFF = dak key release.

Private ringing for incomming SIP calls:

New tst nvram flag available ”ex_profile.flags.private_ringing_SIP”. If ”1” then calls from SIP will use private ringing mode. If “0” then calls will connect as an intercom call with normal priority.

SIPD 01.02 upgrades and corrections

Event “Conversation Outgoing” :

Outgoing calls to SIP: Report Event “Conversation Outgoing” (8) ON when receiving SIP 200 OK, reports OFF at disconnect.

CANCEL_MAIL:

Outgoing calls to SIP: Send CANCEL_MAIL for outgoing call, which cancels call request from that SIP phone.

Events for digits from called SIP:

Outgoing calls to SIP: If called phone presses digits which are sent to AlphaCom as SIP INFO, "Event Trigger Feature" (15) is reported. The digit is sub event (0-9, * = 10, # = 11). Calling AlphaCom station is Event Owner, and called SIP phone number and node number is related to. This could be used for e.g. Dooropening.

Dialing after initial connect sent as SIP INFO:

Outgoing calls to SIP: Digits dialed after initial connect are forwarded as SIP INFO digit messages to the remote SIP device. This can be used for two step dialing from AlphaCom to an external system, or to the PSTN.

Register from port different than 5060 allowed:

Call to SIP: Use port-number stored in registry for contact. Allows SIP device to register from any (random) port, not just 5060. Fixes issue with XLITE 3.0.

Registrar, remove all bindings:

Store only one binding for each user. Remove binding if expires==0. Fixes failure if SIP device registered again from different address/port

SDP media description:

Call from SIP: handle that SDP a= missing, use m=... Fixes issue with XLITE 3.0.

Issue 3059: SIP response handling, call to SIP:

Call to SIP: Improved handling of non-successful SIP responses 300->699: Forward response to AMCD followed before proper disconnect of call towards AMCD. Finally SIP ACK is now sent.
This allows AMCD to handle busy SIP phone properly, and avoids retransmissions from SIP phones due to missing the ACK. Forward 1xx invite responses to AMCD, instead of sending a faked 180 ringing directly on AudioPathSetup from AMCD. Fixes issue with short ring tone when two-step dialing to a SIP gateway.

Call on Hold from SIP:

When receiving a re-INVITE, respond with 488 not acceptable here. Quick fix of problem that X-lite was not able to disconnect a call if the call was put on hold by pressing other line button.

Display name:

Outgoing calls to SIP: don’t send STATION_INFO to AMCD if called name not received from SIP. Fixes issue with blank upper display line for outgoing calls.

Issue 3058: Default route was required:

Fixed failure in IP address lookup if default route not defined for the system, even if no routing was required.

Crash fixes:

Fixed memory crash if SIP 1xx response received out of context. Fixed crash if receiving REGISTER with more than 9 digits in user name

SIP Debug/Trace:

SIP trace/debug console on UNIX socket /tmp/sipd_trace. Connect using "tst -s /tmp/sipd_trace" from local shell. Possible to change trace level during runtime, press digits 0-7. Default level is 4, which prints SIP and AlphaNet messages. Press 0 to stop tracing. Formatting of message trace improved.

SIPd crash debug:

If SIPD crashes due to segmentation violation, a short debug message is printed to “/var/log/sipd_crashes”. Only the last crash is recorded, to avoid filling up the file system.

Issue 3007: SIP - digit during connection:

It is now possible to send digits from AlphaCom to SIP during a SIP connection.

SIPD 01.02 known limitations


SIPD do not remove expired REGISTERs. Can cause problems if changing numbers and node numbers of SIP phones. Workaround: Log in, and delete "/var/opt/amc/nvram/sip_registrar", reset exchange.

Digits during conversation can not be sent or received using RTP (RFC 2833 ). Only SIP INFO supported

Log System (Syslog)


The logging is handled by the syslog-ng log daemon. This can be configured to route the logs to different media. The log can be stored on on-board flash, or sent over the network with different protocols.

Known Issues

Large log files on on-board FLASH

The log is stored on a limited sized Flash partition by a file system. Routines to handle larger log amounts, like automatic clean up of older files have been implemented, but we still experience problems if the log rates get to large. These problems occur before a theoretical log rate versus free space analysis, mainly because of file system issues with a small number of available flash sectors. This file system factor makes it difficult to make an accurate estimate of handled log rates so the following is based on experience:

Limits:

Log rates lesser than 1440 events a day (an average of one each minute) should be handled with no problem.
Log rates of 17280 events a day (one each 5th second) is experienced to give problems.

Guideline:

If you are above 1440 events a day you should evaluate to use the Remote Syslog option, and turn off the Local Filesystem Log.
If you are closer to the 17280 events log rate we strongly advise to use only the Remote Syslog option. 
If your system are logging above the 1440 events a day to the filesystem you should regularly monitor the logs.

Note:

From AlphaCom 10.23 a log limiter on the System and Debug log is implemented, allowing for a maximum of 60 events a hour. 
If this limit  is reached, it will be notified by a log message. Because of this limit the above guidline will only apply 
to the Statistics log.

Hardware Drivers


Rtpdaemon

/opt/amc/bin/rtpdaemon

Rtpdaemon is a user mode service which handle the RTP audio streams. It receives control commands from the AMCD main application on a control socket (/tmp/rtpd). Rtpdaemon transfers and receives RTP packets via standard Linux network sockets. Rtpdaemon packs and unpacks RTP packets. Received packets are buffered before play out. It transfers and receives serialized audio data to the DSP via a DSP driver.

Known problems AMC hardware 8000/2


Issue 2747: RCI not supported on ACE7:

RCI not supported on ACE7. The RCI signals on P1-c19 and P1-c22 are terminated in test points on AMC-IP.

Issue 2741: Redundancy control from APC:

The redundancy control system from APC is not working (software and hardware).

Issue 2787: AMC serial port: No RX, no data on TX:

It turns out that the RS232-drivers on the AMC-IP-board have an automatic shutdown when it detects missing received data (illegal voltage levels). This is fixed in hardware version 8000/4, but it can be fixed on older hardware versions by a minor modification.

Issue 2806: “Temperature Alarm" in AlphaCom E7:

This problem is probably related to the fact that the AMC-IP board never had a connection to the over-temp. signal from the ACE7 backplane. This is related to the problems with RCIs from the same backplane.

AMC Filter board

Issue 2723: RS422/RS485 Signal Pinning:

The pin out for RS422 signals on the filter print for E20 and E26 differs from the pin out on the E7. The Rx+ is switched with the Rx- and the Tx+ is switched with the Tx-. The only consequence is that the same cable can't be used on E7 and the E20-series. From filter print version 3 (DB8001/3) the mapping is correct.
