Q2: What networking protocols does the Prestige 128IMH support?
A2:  Prestige 128IMH supports TCP/IP, Novell IPX and Transparent Bridging (Table 1).

Q3: What WAN capability does the Prestige 128IMH support?
A3: Prestige 128IMH supports ISDN BRI (S/T and U interfaces) with PPP protocol. It also has a built-in V.90 client
      modem. This enables P128IMH to communicate with 56K server at speed of up to 56K through its ISDN interface.
      (Table 1)

Q4: What are the major applications for the Prestige 128IMH?
A4: The applications for P128IMH include Internet Access, Internet Signal User Account, LAN-to-LAN connection and
      Telecommuting server.

Q5: What supplemental phone service does the Prestige 128IMH support?
A5: Prestige 128IMH supports the following supplemental phone service on both POTS ports:

Q6: What network management features does the Prestige 128IMH support?
A6: The Prestige 128IMH supports two methods of system management: Q7: What data compression protocol does the Prestige support?
A7: The Prestige supports STAC compression and the built-in 56K modem supports V.42bis compression.

Please note that STAC is not enabled in Prestige by default, you can enable it in Remote Node setup (SMT menu 11.2, Edit PPP Option). The V.42bis is enabled in the built-in 56K modem by default.

Q8: What is ZyNOS?
A8: ZyNOS is the new Prestige router operating system. It is modular in design and so it is easy for developers to add features for different Prestige models. ZyNOS starts with firmware version number V2.xx. ZyNOS is available for Prestige 128IMH already, and will be available for:

P100MH, P100WH, P128MH, P153, P153X, P100, P100IH, P128 Plus

Only the old models of P128 and P2864I can't support ZyNOS because of limited Flash-EPROM and DRAM size.
 
 

Specific FAQ:



Q1: How do I enter the Prestige SMT menu?
A1: The SMT interface is menu driven, which can be accessed via a RS232 console or a Telnet connection. To access the Prestige via SMT console port, a computer equipped with communication software such as HyperTerminal must be configured to the following parameters. The default console port baud rate is 9600bps, you can change it to 115200bps in menu 24.2.2 to speed up access of the SMT.

Q2: How do I upload ZyNOS code?
A2: There are two ways to upload the ZyNOS code to the Prestige. You can use PCT to install the code via LAN or use the console port to install the code via RS232.

       The procedure for uploading ZyNOS via the console port is as follows.

Q3: How do I upload ROMIFLE?
A3: In some situations, you may need to upload the ROMFILE, such as if you lose the system password, or if you need to reset the SMT to the factory defaults. There are three ways to upload the ROMFILE:       The procedure for uploading via the console port with ATUR3 command is as follows. The PCT (Prestige Configuration Tool), a stand-alone Java-based utility which uses TFTP to allow the backup and restoration of the configuration file via LAN or WAN. Please note that other pure TFTP programs can not upload SMT configurations. A pure TFTP can not make the configuration parameters consistent within the ROMFILE. Inconsistencies among parameters in the ROMFILE may cause problems when you access the SMT.

Q4: What should I do if I forget the system password?
A4: If you forget the system password, you need to upload the ROMFILE to reset the SMT to factory default. After the ROMFILE is uploaded, the default system password will be "1234”.

Q5: Why do we need the input filter in menu 3.1 and call filter menu 11.1?
A5:  Two factory default filter sets have been optimized for Internet connection. They are configured in menu 21 and applied to menu 3.1 and menu 11.5 to prevent NETBIOS triggering the call. You certainly can remove it if you do not need it.

Q6: Why does the connection always drop in about 5 minutes when dialing to Prestige from Win95 Dial-up Networking?
A6: Because Win95 Dial-up Networking is unable to respond to the CHAP challenges from Prestige after the PPP connection
       is established, the "Recv. Authen" option ( in Menu 13, "PPP Options) should be set to 'PAP' only.

Q7: Can I apply the CLID Authentication?
A7: Because the CLID (Calling Line Identification) is sent by the switch, the CLID authentication is switch-dependent. If the
      switch supports Caller ID you can apply the CLID authentication to the Prestige.

Q8: What is SUA? When should I use SUA?
A8: SUA (Single User Account) is a unique feature supported by the Prestige router which allows more than 1 person to access the Internet concurrently for the cost of a single user account. Most ISPs offer two types of service:

A Class C address account allows a company with up to 255 workstations to access the Internet concurrently, while a single user account only allows one user to access the Internet. The service charges for a Class C address account is typically much higher than that for a single user account.

Q9:  What is the difference between NAT and SUA?
A9:  NAT is a generic name defined in RFC 1631, the "IP Network Address Translator (NAT)” SUA (Internet Single User
       Account) is ZyXEL's implementation and trade name for this functionality.

The primary motivation for RFC 1631 is that there is not enough IP address to go around. In addition, great many corporations simply did not bother to obtain legal (globally unique) IP addresses for their networks and now finding themselves unable to connect to the Internet.

Basically, NAT is a process of translating one address to another. An NAT implementation can be as simple as substituting an IP address with another. This allows a network to rectify the illegal address problem mentioned above without going through each and every host.

The design goal of ZyXEL's SUA is to minimize the Internet access cost in a small office environment by using a single IP address to represent the multiple hosts inside. It does more than IP address translation, so that multiple hosts on the LAN can access the Internet at the same time.

Q10: How many network users can the SUA support?
A10: The fixed-size translation table limits the number of simultaneous attempts to access the Internet. A reasonable number will be less than 20 users. Beyond that, the limited modem bandwidth would probably become the bottleneck and any increase in the translation table size would not help.

Q11: How do I capture the PPP log in my Prestige?
A11: The procedure to capture the PPP log in Prestige is as following.

 To enable the capture of PPP log before a connection is established:

 Display the PPP log after a connection is disconnected: Q12: Why can't I make a voice call via the a/b adapter 2 when the internal modem is up and running?
A12: When the internal modem is disabled, the two POTS ports on P128IMH router can be used at the same time. When the internal modem is enabled, only a/b adapter 1 is available for communications.

Q13: What is DNX proxy?
A13: If enabled, DNS Proxy will allow the Prestige to act as the DNS server for the local network. The Prestige will get the IP address of the actual DNS server from the remote site via IPCP negotiation. Note this feature only works if the remote site supports RFC 1877.

Q13.a: How do I turn on DNS proxy?
A13.a:  DNS Proxy is enabled only if the selection of the DHCP field under DHCP Setup in Menu 3.2 is Server and the Primary DNS Server field in Menu 3.2 is set to 0.0.0.0. (this is the factory default). If the DNS Proxy is enabled, the Prestige will assign its IP address as the Primary DNS in response to DHCP requests on the local network.

Q13.b: How do I set DNS other than Prestige's IP address?
A13.b: If the DNS is already known to you, you can enter it in the Primary DNS server and Secondary DNS server fields in Menu 3.2 to respond to the DHCP requests on the local network if DHCP Server function is enabled.

Q14: What is a Nail-up Connection and when do I need to use it?
A14: A Nailed-up Connection, when enabled, will emulate a leased line connection even though the physical line is a dial-up connection. The Prestige will dial and hold up a connection, without any traffic requesting it.  When you want the link to be always up, you need to use it.

Q15: What are Device filters and Protocol filters?
A15: In ZyNOS, the filters have been separated into two groups. One is called the device filter group, and the other is called the protocol filter group. Generic filters belong to the device filter group, TCP/IP and IPX filters belong to the protocol filter group.

Q16: Why can't I configure device filters or protocol filters?
A16: Because in ZyNOS, you can not mix different filter groups in the same filter set.

Q17: How can my client connect to my server through Prestige which is running SUA?
A17: You need to configure Menu 15 SUA - Server Setup. Enter the port number if you know it, e.g. port 21 for FTP server, and then enter the IP address of this FTP server. The remote clients can then access the FTP serve by using Prestige's Internet address (WAN IP).

Q18: How does 'Dial Prefix to Access Outside Line' in Menu 2 (European firmware) work?
A18: This is the number that will be placed in front of the outgoing call phone numbers when you make an outgoing call.

Q19: What are supplemental services?
A19: ISDN Supplemental Services refers to Call Waiting/Call Hold/Call Retrieve, Three-way Calling (Conference/Transfer/Drop), Call Forwarding, and Reminder Ring on the Prestige POTS ports. There are services on the serving Central Office switch that works in tandem with the Prestige software which must be enabled.

19.a. Can I do call waiting?

Yes.  You need subscribe Additional Call Offering (ACO) (in Europe the same service is better known as “Call Waiting”) on your ISDN line in order to utilizing the Call Waiting/Call Hold/Call Retrieve feature.

19.b. How do I do call waiting/Call Hold/Call Retrieve?

19.c. Why doesn't Call Waiting work as expected?

An incoming caller will receive a busy signal if:

If no action is taken to answer the call (call waiting indicator tone is ignored), the call waiting tones will disappear after about 20 seconds.

19.d. Can I do Conference Calls?

Yes.  The three-way Calling (Conference/Transfer/Drop) feature requires flexible calling on your ISDN line.  You may want to check with your PTT to confirm if these services are available to you.

19.e. How do I do Conference Calls?

Press the flash hook button and immediately release it to put the existing call on hold and receive a dial tone.

19.f. How do I 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.
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.

19.g. How do I do Call Transfer?

Call Transfer is a variance of three-way and allows you to transfer an active call to a third party.  If you wish to transfer an active call to a third party and inform him about the transferred call, the steps are:

19.h. How do I do blind Call Transfer? The call will be automatically transferred.

19.i. What is Call Forwarding and how do I do it?

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.  Please request your telecom for the instructions to activate or deactivate the Call Forwarding feature.

19.j. Why doesn't my answer machine on POTS port stop recording?

Answer machine will stop record when it receives busy tone or detects a period time of silence.  If your POTS will connect to answer machine, you need set S78.5 and S78.6 to set the silence time. When it sets to 5 sec, Prestige will be silent 5 sec after remote hangs up, and then produces busy tone. Since most of the answer machines detect busy tone, so the default is 0 sec. If you have an answer machine detecting silence, you need set the s78.5 s78.6 to meet your need. This should be added at initstring by the following CI command.

S78.6  S78.5  Silence time 
0 0 0 sec
0 1 5 sec
1 0 10 sec
1 1 15 sec

Q20: What are CLIP and CLIR in Advanced Setup of Menu 2 (European firmware)?
A20:  The CLIP or CLIR refers to CLID Presented or Restricted The Prestige can set the CLIP/CLIR bit in the SETUP message to request the Switch to include calling party number or not when the switch sends the SETUP message to the called party. Therefore, before using it you need to subscribe to it first from your telecom as a supplemental service.

Q21: Does ZyNOS support IRC, RealAudio, CU-SeeME?
A21: Yes. IRC which is an Internet Chat service like NetMeeting is supported in our SUA mode.  RealAudio
        and CU-SeeMe are also supported.

Q22: What do the error code in syslog mean?
