Release Note on TA128 Version 2.00b (public betatest)
======================================================
Fixed Bugs:
-----------
1. Set baud rate as 19200/9600/4800/2400 bps, key in T<CR>AT<CR>...
sequence there will be no response from TA.
2. AT*HCn's descrption in on-line help is wrong.
3. AT&F doesn't update AA LED status.
4. For USA version, if switch type is AT&T point-to-point, sometimes
layer 1 can not activate.
5. For USA version, if switch type is NI1, callback function does not work.
6. The received packet length of D-channel is not correct.
7. Issuing "AT*Ax",x=0,2-7 to set the speed of DTE port 2 other than 115.2
Kbps and saving to the user's profile by issuing "AT&W0Z0". After power
off and on the TA, DTE port 2 does not accept any AT command until
issuing command to DTE port 1 firstly.
8. CAPI 2.0 driver can not be used with CANDI.
9. Issuing "ATC$" to view EPA will get some garbage.
10. For DTE port2, TA can not send SETUP message with Low Layer Compatibility
while making an outgoing call.
11. When using the phone features and trying to send BUSY to the caller
Flash/5, the TA128 sends DISCONNECT with 'Call reject' instead of
'User busy'.
12. While intercom or 3 way conference, only Phone 1 can answer an incoming
call. Phone 2 should be able to answer the call.
New Implementation:
-------------------
1. Caller ID display for POTS ports.
When telephone call is coming, if physical DTE port is not occupied
by any logical DTE channels, Caller ID and Calling ID will be displayed
when s84.4=0.
2. AT*GC1: 2 changes.
(1). Compare Calling Party Number (CGPN) with the stored numbers from the
right digit to the left digit. So 8005552000 will match 5552000.
(2). Based on the shorter one, so the CGPN can be longer or shorter than
the stored numbers.
3. Leased line function. Using following command to configure:
3.1. ATDCn n=1,2,3 excites leased line connection on originate mode.
DC1 - excites leased line connection using B1 channel on originate
mode
DC2 - excites leased line connection using B2 channel on originate
mode
DC3 - excites leased line connection using both B1 and B2 channel
on originate mode
3.2. ATABn n=1,2,3 excites leased line connection on answer mode.
AB1 - excites leased line connection using B1 channel on answer mode
AB2 - excites leased line connection using B2 channel on answer mode
AB3 - excites leased line connection using both B1 and B2 channel on
answer mode
3.3. AT&In n=0,1,2,3 normal/leased line options
&I0 - normal dial-up phone line. (default)
&I1 - leased line function in B1 channel only, dial-up function in
B2 channel
&I2 - leased line function in B2 channel only, dial-up function in
B1 channel
&I3 - leased line function in both B1 and B2 channel.
4. Feature phone function: flash/6 - designate local phone to answer incoming
call which ringing another phone.
5. Add "AT&W" to save DTE#2 B-channel protocol in NVRAM: If you first
time upload firmware that includes "AT&W" function for DTE#2, please set
the B channel protocol and set it into NVRAM (AT&W).

Release Note on Omni TA128 Version 2.00a (public betatest !)
=============================================================
1.The firmware's file names for various switch type are as follows:
FILENAME SWITCH TYPE
1.1 "OI_E200A" ------ DSS1
1.2 "OI_A200A" ------ USA
1.3 "OI_G200A" ------ 1TR6 (GERMANY only)
2.Fixed the Bugs:
=================
2.1 For AOC function, a second call delete the charging information from
channel B1, but not real. After the next charging unit come for B1
channel, the lost units shows correctly again and the A/B adapter send
this accumulated units as 16 kHz metering pulse to the connected phone.
By the way, the phone display wrong charging information.
2.2 It's necessary to analysis the High-Layer Compatibility information
element, especially G4 fax. An incoming call with G4 fax have to be
routed to correspondable a/b adapter.
2.3 Making an outgoing data call to a BUSY TA may get "NO CARRIER" instead
of "BUSY".
2.4 While calling an unassigned number using analog port, the inband
information will come from switches. But the TA128 sends a busy tone
instead of connect this inband information.
2.5 For Japanese version, while making an outgoing phone call with
subaddress using analog port, then there are two errors in SETUP
message:
1) the length of called party number is not correct.
2) missing the byte of AFI ( Authority and Format Identifier ) for
called party subaddress with the type of NSAP X.213/ISO 8348 AD2.
2.6 While making a user-to-user information ( using ATT command ), the TA
send wrong message to switch.
2.7 For s50 function, while the value of s50 is more then 128, making a
data call will cause TA reset.
2.8 The answer side sets "ATE0Q1" "AT*G4" or "AT*G5". while calling back a
incoming call ,the message "CallBack ATDIS0" will be displayed.
2.9 Fixed the bug in the comformance test of Singapore.
2.10 The modem will crash when the server reguest PAP but Win95 require
encrypted password.
2.11 For PPP/MP, the second call will wait 2 seconds to dial out after the
first passes authentication.
2.12 Issuing "ATCG", the activated of layer 1 fails.
2.13 For s124 setting, there are some problems to send LCP-echo.
2.14 The timer for S124 value is incorrect to send LCP-echo.
3.Newly implemented features
============================
3.1 Sync Data
-------------
3.1.1. AT&M1: asynchronous (=async) command, synchronous (=sync) mode.
At call site, issue "AT&M1" and "ATB11" ( V.110, sync 64K ), then
LLC with sync mode will be included in the SETUP message.
AT answer site, only issue "AT&M1", the Elite will check LLC of
incoming SETUP message and connect with sync data.
3.1.2. AT&M3: synchronous mode.
V25bis command set for this synchronous mode is available.
AT*I1 have to be issued for enabling V25bis command set.
3.2 CAPI 2.0
------------
3.2.1 A public-beta version of the CAPI 2.0 driver was released
simultaneously with the F/W version 2.00a.
Supported Layer 2 and Layer 3 protocols are:
X.75/transparent,
X.75/T.70 (for T-Online),
X.75/ISO8208 (for European File Transfer)
HDLC/transparent
3.2.2 Two applications on the same PC can work concurrently, each using
one of the two B-channels.
3.3 Miscellaneous
-----------------
3.3.1 S50, inactivity timer. The Elite counts when there is no data flow
in or out of the RS-232 serial port. A connection is disengaged when
the counter reaches the preset value. Set '0' to disable this
function. This function is available in PPP protocol.

3.Newly implemented features
============================
3.1 CAPI.DLL v1.1 Profile A
-----------------------------
3.1.1 A public betatest version 0.96 of the CAPI 1.1 profile A driver for
Windows (CAPI.DLL, 16-bit) was released simultaneously with the
f/w version 2.00
The supported B-channel layer 2 and layer 3 protocols are:
HDLC / transparent (used for some network connections with WISPA, etc)
X.75 / transparent (used for most standard connections, eg. to BBS)
X.75 / T.70NL (used for the German T-Online Service)
X.75 / ISO-8208 (used for "EFT" = Euro File Transfer)
Bit Transparent (for some G3 Fax applications).
Two applications on the same PC can work concurrently, each using
one of the two B-channels.
[Note] We established a public mailing list on the Internet for
testing this CAPI.DLL. If you are interested, please
subscribe to this mailing list:
send an eMail to "majordomo@zyxel.co.at" and in the message
body write following two lines:
--------------------------------------------
subscribe capi-testers your.name@site.domain
end
--------------------------------------------
where "your.name@site.domain" is your full Internet eMail
address.
If you had subscribed successfully you will receive a
confirmation of your subscription in an eMail within minutes.
The "Welcome to the capi-testers mailing list" eMail contains
more background information ....
3.1.2 EAZ to MSN mapping function for CAPI mode. Users can use
AT&Zn=xxx/sss/, n=0-9 (denotes the EAZ), xxx = phonenumber, sss =
subaddresss to do this mapping. For outgoing calls, the Elite
receives "Source EAZ" (0-9) from the application and uses the
appriopriate phone number as Calling_Party_Number/Subaddress.
For incoming calls, the Elite checks Called_Party_Number/Subaddress
and uses the matched phone number register's pointer (0-9) as
"RequestedEAZ" to the applications.
3.2 Charging Information
------------------------
3.2.1 AOC (Advice Of Charging) function: now you can use "ATCH?" to view
the charge information of the last call if the network had sent the
message. Please check with your ISDN Central Switching Office if any
of the following EuroISDN supplementary services - according to the
ETSI specifications - could be actived (because they are not
supported in all European countries !)
AOC-S/currency = Advice of Charging on call Setup time
AOC-D/currency AOC-D/units = Advice of Charging During a connection
AOC-E/currency AOC-E/units = Advice of Charging at the End of a call
3.2.2 Metering Pulse function ("ATS89.6=1") in case of the "AOC-D/units"
ISDN supplementary service: for Germany (16 kHz), Switzerland (12 kHz)
and Austria (12 kHz). Therefor it is necessary to set the correct
ISDN country code ! Please check the current ISDN country code with
the command "AT#H"
[Note] Users can use the following command to change the country code:
ATS38=4 for enable changing country code function.
AT#Gxxx for enter country code xxx.
ISDN country code list:
Sweden 250 HongKong 242
Taiwan 238 Germany 237
Italy 236 Japan 234
Austria 233 Switzerland 225
ATTENTION: please don't set any other ISDN country code than specified
otherwise your ZyXEL ISDN product won't work correctly and
then the behaviour for D-channel singalling would cause
malfunction (especially if some country specific features
will not be supported or implemented in the ISDN Central
Switch firmware for the ISDN basic rate access in your
country) !
3.3 New protocols for DTE port #2
---------------------------------
3.3.1 implementation of X.75 and V.120.
3.3.2 multiauto mode auto-detect/connect PPP, X.75, V.120 protocols.
3.3.3 DTE port 2 will answer to matched "called party number" with MSN
setting (refers to AT&ZI5 command).
3.3.4 One more S register bit is to configure DTE port 2 to answer the
incoming data call when DTE port 1 is busy (in connected state),
even if the MSN (at&ZI5) is not matched.
S87.7 = 0 : DTE port 2 will only answers the incoming data
call with matched MSN number (default).
S87.7 = 1 : DTE port 2 answers incoming call when port 1 busy.
(useful for server applications)
3.4 New POTS port features
--------------------------
3.4.1 Intercom / Transfer / MultiAnswer / Call Waiting /
