ZyXEL Prestige P128

1.50 Release Note/Manual Supplement

Date: August 17, 1998

This Release Note/Manual Supplement contains information about the new features, and bug

fixes since the incremental release v1.42(B.03I).

The New Features section lists the new features added to this release. Please read through the

Enhancement Details section for detail information. A new section, Changes not Compatible

to Previous Versions, is added to this release notes. It is important to read it too.

1New Features

SUA Enhancements

In this release, SUA has been enhanced to support the popular applications: Microsoft’s

tracert under Windows9x and Windows NT, CuSeeMe, IRC, RealAudio, VDOLive,

Quake, and PPTP. Besides above, multiple SUA servers are supported.

Advanced ISDN Features

ISDN Supplementary Services are supported in this release. These services work

properly only if the needed functions subscribed from the Telephone Company or PTT.

B-channel, CLID, and WAN IP Address Shown on Menu 24.1

B-channel, CLID, and WAN IP address are shown on Menu 24.1. Due to the space

limitation in Menu 24.1, Menu 24.1 has been separated into to two screens. The original

static information in Menu 24.1 has been moved to Menu 24.2.1. Now, Menu 24.1 only

displays the dynamic information.

2Changes not Compatible to Previous Versions

2.1 ISDN EPA Mechanism is Moved to PC

The CI (Command Interpreter, menu 24.8) command, "isdn ana display", is disabled in this

release. A new CI command "sys epalog" is added for displaying the ISDN raw trace data. "isdn

ana display" could not work with Telnet before, but "sys epalog" works fine with Telnet. So you

do not have to rely on terminal emulator via serial port to capture the ISDN trace any more.

A new DOS tool - epapc, will be used to decode the ISDN raw trace data into meaningful Q.921

and Q.931fields. epapc is part of this release. If you have difficulties to run epapc, please send

the raw ISDN trace to ZyXEL support for decoding. The proper steps to take the raw ISDN trace

are:

1. type “isdn analyzer on”

2. try your ISDN call now

3. after failed ISDN connection type “isdn analyzer off”

4. Type “sys epalog”

5. Start to capture the data displayed on the screen

6. Type <CR> to show the raw ISDN trace on screen

7. Press <space bar> to keep Prestige displaying the trace until hit end

8. Stop the capturing mechanism

2.2 Busy Tone Generated after Far-end Hanging up

In the previous releases, Prestige kept silent after far-end hanging up the phone. In this release,

Prestige generates busy tone after far-end hanging up. There exists a side effect for those

answering machines based on silent to detect the end of the message. The work around is to

issue a CI command and reboot the Prestige.

•if the answering machine is on POTS port 1, the CI command is:

isdn set initstring s78.0=1

•if the answering machine is on POTS port 2, the CI command is:

isdn set initstring s78.1=1

•if the answering machines are on both POTS ports, the CI command is:

isdn set initstring s78.0=1s78.1=1

If you do not want to reboot your Prestige after issuing the above CI command, you can issue

another CI command to activate it:

isdn send initstring

You can reset the function to default by issuing:

isdn set initstring

3Supported Platforms

v1.50(B.00) supports Prestige models: P128 and P128L.

4Enhancement Details

4.1 SUA Enhancements

SUA has been enhanced to support the popular Internet applications: MS tracert, CuSeeMe,

IRC, RealAudio, VDOLive, Quake, and PPTP. There is no configuration needed for supporting

these applications.

For multiple SUA server support, the Server IP Addr field in Menu 4 and 11.2 has been

removed and a new Menu 15 is added.

Menu 15 - Multiple Server Configuration

Port # IP Address

--------- -----------------

1. Default 0.0.0.0

2. 0 0.0.0.0

3. 0 0.0.0.0

4. 0 0.0.0.0

5. 0 0.0.0.0

6. 0 0.0.0.0

7. 0 0.0.0.0

8. 0 0.0.0.0

There are up to eight SUA servers can be configured in this menu. The first one is reserved for

the default server, and it can not be changed. You only need to assign the IP address to this

default server. For other SUA servers, you need to assign them both of the Port number and the

IP address.

If the default server has been configured, the entire unknown (port number is not configured in

this Menu, nor in SUA table) WAN incoming IP packets will be routed to this IP address.

Otherwise, Prestige will discard them silently if they are neither Telnet (port number 23) nor

Authentication (port number 113) packets. For Telnet packets, Prestige will perform as Telnet

server in this case. For Authentication packets, Prestige will reject them.

The most often used port numbers are:

4.2.1 Before You Begin

Advanced ISDN Features refers to Call Waiting, Call Hold, Conference Calling, Call Transfer,

and Reminder Ring on the Prestige POTS ports. There are services on the serving Central

Office switch that works in cooperation with the Prestige software must first be enabled. These

services usually are extra charges in addition to your monthly payment.

Additional Call Offering (ACO) (in Europe the same service is better known as “Call Waiting”) is

required to be subscribed on your ISDN line in order to utilizing the Call Waiting (CW) feature.

Flexible Calling is required on your ISDN line in order to using the Three Way Calling (Call

Conference), or Call Transfer features. You may want to check with your phone company to

confirm if these services are available to you.

In some cases, your telephone company may enable the subscribed services on your first

directory (phone) number only. You have to request your telephone company to enable the

services on your second directory number as well if you do need the features on both of the

POTS ports.

4.2.2 Advanced ISDN Features Supported by Northern American Version

4.2.2.1 Menu 2 – ISDN Setup

If the advanced ISDN features are enabled on both of your PORT ports, please follow the

suggestion in this section in order to making the advanced ISDN features work properly on both

of them. It is important to select Phone 1 in Incoming Analog Call field under 1st Phone field,

and to select Phone 2 in Incoming Analog Call field under 2nd Phone field.

For example, if you have two telephone numbers, 5552000 and 5554000, and you want to assign

5552000 to POTS port 1, then configure it as:

Menu 2 - ISDN Setup

Switch Type= xyz

B Channel Usage= Switch/Switch

1st Phone #= 5552000

SPID #= 0555200001

Incoming Analog Call= Phone 1

2nd Phone #= 5554000

SPID #= 0555400001

Incoming Analog Call= Phone 2

Advanced Setup = No

If you want to assign 5554000 to POTS port 1, then configure it as:

Menu 2 - ISDN Setup

Switch Type= xyz

B Channel Usage= Switch/Switch

1st Phone #= 5554000

SPID #= 0555400001

Incoming Analog Call= Phone 1

2nd Phone #= 5552000

SPID #= 0555200001

Incoming Analog Call= Phone 2

Advanced Setup = No

The important point is to select Phone 1 in Incoming Analog Call field under 1st Phone field,

and to select Phone 2 in Incoming Analog Call field under 2nd Phone field.

4.2.2.2 Menu 2.1 – ISDN Advanced Setup

In Menu 2, move cursor to the Advanced Setup field and select Yes, then press the “ENTER”

key. This will pop up the ISDN Advanced Setup menu for configuring supplemental services and

other option as shown below in menu 2.1.

Menu 2.1 -- ISDN Advanced Setup

ISDN Features Access Code:

Conference Call= 60

Call Transfer= 61

Call Drop= 62

Call Forwarding= 57

Phone 1 Call Waiting= Enable/Disable

Phone 2 Call Waiting= Enable/Disable

Preferred Phone # for 1st Out Data Call= None/1st/2nd

Please note that the default values entered in the feature access code fields are the values that

are specified by the NI-1 standard. Please ask your Telephone Company about the right access

code for your ISDN line provision. For certain RBOCs like Pacific Bell, or switches like the

Northern Telecom Custom, the values could be different from above. Take the access code

provided by your telephone company; otherwise, our recommended values are:

Access Code Feature

4Conference Call

5Call Transfer

6Call Drop

57 Call Forwarding

By toggling the Phone 1 Call Waiting and Phone 2 Call Waiting fields, you can enable and

disable the Call Waiting feature on the POTS port phones. Default is to disable the Call Waiting

feature on both phones.

The purpose for adding the Preferred Phone # for 1st Out Data Call field is to allow user to

reserve a Directory (Phone) number for incoming calls. When there is no active data or voice

call, the first Directory (Phone) number (DN-1) will be used to place the out data call if None or

1st is selected, and DN-2 will be used if 2nd is selected. The difference between None and 1st

is the B-channel requested in Setup message from Prestige to switch. There is no B-channel

preference set in the Setup message if None is selected. The B-channel preference is B1 if 1st

is selected, and the B-channel preference is B2 if 2nd is selected. Here is a brief description

about the choices of this field:

None: DN-1 is used to place the out data call.

1st: DN-1 is used to place the out data call, and the preferred B-channel is B1.

2nd: DN-2 is used to place the out data call, and the preferred B-channel is B2.

We have to emphasize that the above selection is only a preference. Switch may reject the B-

channel request; and different DN is used because the desired Directory (Phone) number used

by other call.

4.2.2.3 Call Waiting

ISDN Call Waiting allows you to place a call on hold while you answer another incoming call on

the same phone (directory) number.

4.2.2.3.1 How to Use Call Waiting

•Put your current call on hold and answer the incoming call - after hearing the call waiting

indicator tone, press and immediately release the flash hook button on your telephone.

•Put your current call on hold and switch to another call - press and immediately release the

flash hook button on your telephone.

•Hang up your current call before answering the incoming call – hang up the phone and wait

for the phone to ring. Then answer the incoming call.

•Hang up on the current active call and switch back to the other call – hang up the phone and

wait for the phone to ring. Then pick up the phone to return to the other call.

4.2.2.3.2 Why Call Waiting not Work as You Expected

1. An incoming caller will receive a busy signal if:

•you have two calls (one active and one on hold; or both actives by using Three Way

Calling) on the Directory (Phone) number the incoming caller is attempting to reach.

•you are dialing out by using the Directory (Phone) number the incoming caller is

attempting to reach, but have not yet established a connection.

2. If no action is taken (call waiting indicator tone is ignored) to pickup the call, the call waiting

tones will disappear after about 20 seconds.

3. There exists a rollover call. Please take a look of Call Rollover Support section for detailed

information.

An application note for Northern American Call Waiting examples is included in Appendix A

4.2.2.4 Call Rollover Support

In the previous releases, Prestige did not support Call Roller. Prestige supports this feature in

v1.50. Unfortunately, this feature is switch dependent. Call Rollover Works only if the Switch

Type is AT&T NI-1.

4.2.2.4.1 Incoming Call Rollover

If the Directory (Phone) number, DN-1, associated to POTS port 1 is used by a data call (it might

be another analog call to POTS port 2 even though it is really rare), the incoming analog call

intended to DN-1 will be routed to POTS port 1. It is called incoming analog call rollover. None of

the advanced ISDN features works for this incoming analog rollover call.

If the Directory (Phone) number, DN-1, associated to POTS port 1 is used by an analog call, the

incoming data call intended to DN-1 will be answered. It is called incoming data call rollover. The

advanced ISDN features do not work on the analog call if there is an incoming data rollover call

at the same time.

4.2.2.4.2 Outgoing Call Rollover

For outgoing data call, there is no problem for Prestige to pick the unused Directory (Phone)

number to place the call. So, there is no outgoing data rollover call problem. It is different for the

outgoing call initiated by the POTS port.

If the Directory (Phone) number, DN-1, associated to POTS port 1 is used by a data call,

Prestige will use DN-2 as the caller number to place the call from POTS port 1. It is called

outgoing voice call rollover. Call Waiting does not work in this case even though other advanced

ISDN features work fine.

4.2.2.5 Three Way Calling (Call Conference)

The Three Way Calling feature allows you to add the third party to an existing call. The Flexible

Calling service must be subscribed from the Telephone Company.

4.2.2.5.1 How to Add the Third Party to the Existing Call

•If you wish to add the third party to an existing call, the steps are:

1. Press the flash hook button and immediately release it to put the existing call on hold

and receive a dial tone.

2. Dial the third party.

3. Inform the third party about the conference.

4. When you are ready to conference the call, press the flash hook button and immediately

release it to establish a Three Way Conference Call.

•If you wish to cancel your attempt for some reason (the third party’s line is busy, or no one

answer, …), just hang up the phone and pick it back up after the phone ringing.

4.2.2.5.2 How to Remove a Party from the Three Way Calling

•If you wish to drop the last one added to the Three way calling call, just press the flash key.

The last call that was added to the conference will be dropped.

•If you wish to drop yourself from the conference call, but allow the other two callers to remain

connected. Just hang up your phone. If the other two remain on the line, your drop will not

impact their connection.

4.2.2.6 Call Transfer

Call Transfer allows you to transfer an active call to a third party. The Flexible Calling service

has to be subscribed from the Telephone Company. In fact, Call Transfer is a variance of Three

Way Calling.

If you wish to transfer an active call to a third party and inform him about the transferred call, the

steps are:

1. Press flash to immediately put the existing call on hold and receive a dial tone.

2. Dial the third party.

3. Inform the third party about the transfer call.

4. Press the flash hook button and immediately release it to establish a Three Way Conference

Call.

5. Hang up the phone to complete the transfer.

If you wish to do a blind transfer to the third party, the steps are:

1. Press flash to immediately put the existing call on hold and receive a dial tone.

2. Dial the third party.

3. Before the third party picks up the call, you can transfer the call by pressing the flash and

hanging up. The call will be automatically transferred.

4.2.2.7 Call Forwarding

The Call Forwarding feature is supported by ISDN switch directly. The Call Forwarding feature of

the POTS port can be activated and deactivated by using the phone set. The Call Forwarding is

a telephone feature and will not impact incoming data call. Please request your phone company

for the instruction activate or deactivate the Call Forwarding feature. Here is the instruction

written in Custom Calling Service section of Pacific Bell White Pages:

To turn on, press 72#. At the dial tone, enter the number you want your calls forwarded to. If the

line is busy or does not answer, repeat the above process and it will be activated even if the line

is still busy. To Turn off, press 73#.

4.2.2.8 Reminder Ring

Prestige will alert you every time a call has been forwarded by sending a single short ring to your

telephone. This feature is just to let you know that your calls are being forwarded.

4.2.3 Call Waiting Support for DSS-1

In this release, the only supplementary service supported is Call Waiting. Please move cursor to

the Advanced Setup fields in Menu 2 and select Yes, then press the “ENTER” key to pop up the

ISDN Advanced Setup as below.

Menu 2.1 -- ISDN Advanced Setup

Phone 1 Call Waiting= Enable/Disable

Phone 2 Call Waiting= Enable/Disable

By toggling the Phone 1 Call Waiting and Phone 2 Call Waiting fields, you can enable and

disable the Call Waiting feature on the POTS port phones. Default is to disable the Call Waiting

feature on both phones. Here is a brief description about the choices of this field:

Disable: disable the Call Waiting feature on the specific phone.

Enable: enable the Call Waiting feature on the specific phone.

4.3 B-channel, CLID, and WAN IP Address Shown on Menu 24.1

Menu 24.1 has been separated into to two screens. The original static information in Menu 24.1

has been moved to Menu 24.2.1 as below.

5Bug fixes

1. Some Prestige users experienced system hang once a couple of weeks. When it happened,

it needed human intervention to power cycle the Prestige for making it work again. In this

release, Prestige will re-boot itself to eliminate the human intervention.

2. Prestige used to have a bug in its SUA mechanism. This bug caused Prestige dropping the

fragmented WAN incoming IP packets. The symptom is that you have problems to certain

Web sites if the Prestige is configured SUA. It is fixed in this release.
