-
- Since the ZyXEL modem has many features of special interest to Telecom
- readers, I thought you might be interested in this review that I wrote
- for the New England Fidonet Sysops.
-
- Items of Telecom note are: Caller ID, Distinctive Ring, Voice
- record/playback, DTMF detection.
-
- BASIC INFORMATION
-
- Make: ZyXEL
- Model: U-1496E (External)
- ROM: V 5.03c M
- Speed: 14,400 in V.32bis, 16,800 with other ZyXEL modems
- FAX: Group III FAX with FAX software included. Does Class II modem
- FAX commands and is compatible with many FAX software packages
- Chip Set: ZyXEL (Not Rockwell)
-
- SPECIAL FEATURES
-
- This is the only modem that comes with software that will allow
- Binkley or FrontDoor to answer a BBS call, find out that it is a FAX
- call and chain off to the FAX software to receive a FAX.
-
- Will decode and report Caller ID (caller number delivery) information
- if this information is available on your phone line. It will also
- deliver caller's name, if this information is provided by your phone
- company.
-
- Remote configuration.
-
- Two types of security features. One does dial back, the other works
- only with another XyXEL modem.
-
- You can tell the modem to only answer on one of more distinctive ring
- patterns. The type of phone service is called RingMate by New England
- Telephone, but has different names in every part of the country.
-
- Has its own built in dialing directory.
-
- Adaptive block size for bad lines.
-
- Maintains statistical performance information that can be read back in
- human readable form.
-
- Special Voice/Tone Information.
-
- 1. Can read incoming touch tones (DTMF) and pass information on to
- your computer.
-
- 2. Has facilities to play a digitized voice recording out over the
- phone line or through the modem's speaker.
-
- 3. Has facilities to digitize and record voice messages coming in
- over the phone line.
-
- If you combine items 1, 2, and 3. You see that you can build a
- voicemail system, or a front end that will answer your phone with a
- message and ask callers to select from Voice, Data, or FAX. However,
- I have not found any existing software that will do this. They do
- give you a program that has some of these features, but mostly for
- demonstration purposes.
-
- There are other modem models that have a better voice digitizing method
- that compress speech into smaller disk files.
-
- They have a public access BBS that has information on using their
- modems with many different FAX and communications packages.
-
- When they issue a ROM update, if you have access to a PROM burner, you
- can download the code from their BBS. Otherwise, you can get an
- upgraded ROM from them.
-
- There is a light on the front panel indicating signal quality.
-
- THE GOOD NEWS
-
- My BBS is the Fidonet<->Internet Gateway for nets 101 and 322. As
- such I have many incoming and outgoing mail connections with other
- Fidonet systems. This is the third 14,400 FAX modem I have tested.
- The Supra and Zoom modems were both returned as being unacceptable for
- a variety of different reasons. The ZyXEL seems to do the job quite
- well.
-
- The unit comes with a heavy duty power transformer (unlike the Zoom or
- Supra), and seems well built.
-
- With the exception of one system (see below), I can connect with all
- other modems without any special setup strings.
-
- THE BAD NEWS
-
- The FAX software that comes free with the modem is not very
- sophisticated. If you only use FAX infrequently, you will be able to
- use it, but if you are a frequent FAX user, you will likely want
- something better.
-
- The manual has most of the information you might want, but is not well
- organized. The Zoom manual was much better and had more information.
-
- I had no reason to remove the case, but I wanted to take a peek
- inside. It was difficult getting the case open. The instructions in
- the manual on this topic were not all that clear.
-
- The lights inside the modem are set back from the front panel far
- enough so that it is difficult to see what is going on when you look
- at them from an angle. The more expensive model has a digital
- display.
-
- There are too many lights lit when the modem is not connected so that
- it is difficult to tell from a distance if the modem is on-line.
-
- The lights are arranged in such a way that you need to look very
- carefully to know if you have an error correction connection.
-
- You can tell from the lights if you have a v.32 connection, but you
- can not tell the speed of the connection.
-
- I have a problem which may be unique to my local phone exchange. I
- have had this problem with some brands/models of modems in the past,
- but not all. On an outgoing call, when the number called is busy,
- about 10%-15% of the time, the ZyXEL modem will report RINGING rather
- than BUSY. This just means that the call attempt will take a little
- longer to abort. To deal with this, I have set Binkley to "RingTries 7".
-
- I had one other problem which seems to have gone away since ZyXEL sent
- me a replacement modem. About every three or four days the modem
- ended up in a state where the touch tones (DTMF) being generated by
- the modem were not recognized by the phone company. Dial tone would
- come up, the tones would go out, and dial tone would still be there.
- The only way to clear this was to power off the modem and power it
- back up. I have been using the replacement modem for about three
- weeks now and the problem has not come back. The second modem had a
- later ROM revision, so I'm not sure if it was a ROM problem or a modem
- problem.
