26. Supported Countries

26.1 In which countries does isdn4linux work?

We are aware of at least the following countries:

If your country is not on this list does not mean it is not supported. It just means we have not seen a confirmation about its usage there. Check the mailing list for other users from your country.

26.2 country_certified: Is isdn4linux approved for use by the telecommunications authorities?

Germany

That depends on the driver used. For active cards, the approval covers the entire card including its firmware. Thus the approval also covers the use of these cards with isdn4linux. The Elsa Quickstep 1000 PCI driver is currently certified in Germany (and hence in most european countries). This applies to the 2.0.36 kernel version.

Other countries

Besides those countries that accept a german certification, we don't have any information... does anyone know more?

(Translator's note: Here are some notes we've received that are not yet in the main FAQ:

-Elie Milgrom em@info.ucl.ac.be reports that in Belgium the MSN is "Nothing special: a MSN is just a 'regular' phone number here."

-Sunny Marueli sunnym@netvision.net.il reports that "isdn4linux works in Israel as well (with Teles PnP)."

-Jerome Lefranc decision@calva.net reports for France that: "(1) if you don't have MSN, you need to specify as local number only the last 4 digits of you phone number. ex: 01 41 33 67 87, local phone number is 6787;

(2) you can use sub-address number (not MSN). ex: 01 41 33 67 87 (phone number), 02 (sub-address), then the local phone will be 6787.02 with the HiSax driver."

-Niall O Broin nobroin@esoc.esa.de reports that in Ireland he's had success during some limited testing on a Telecom Eireann line (the only provider of end-user ISDN lines in Ireland). He wrote:

"Not what you'd call comprehensively tested, but a machine with an AVM Fritz ISA card

1) Call itself using TTY emulation 2) Call the test numbers mentioned in the FAQ using TTY emulation 3) Initiate a synchronous PPP connection 4) Receive a synchronous PPP connection

Apart from the above, no other testing was carried out but the above functions all worked just fine."

-I'm not sure how to set up an EAZ/MSN in the UK, but Paul Slootman paul@isdn4linux.de wrote:

"I have information that in the UK, there are no "normal" MSNs. Each MSN is actually a single digit, 0 - 9, corresponding to the last digit of the actual phone number. Apparently in the UK you either have *no* MSNs, or 10 MSNs; you then always get a block of 10 sequential numbers. I've also heard that from middle October, BT is going to offer "normal" EuroISDN, which they will call ISDN-2e (their current offering is ISDN-2). This will also have facilities such as call forwarding etc. Look somewhere on www.andrews-arnold.co.uk/isdn/ for more info.")

26.3 German Pecularities (1TR6)

26.4 Which EAZ should I use for i4l?

You can use all available EAZ. However, two EAZ have a special meaning and can cause problems:

EAZ 0: global call (all telephones ring)
EAZ 9: global call (no telephone rings)
Gernot Zander hifi@scorpio.in-berlin.de wrote about this on 6. Jan 1997:
I would not use 0, for my taste it is too likely that i4l will steal all voice connections.

26.5 I use 1TR6 on an extension - the extension number has more than one digit (e.g. 206). What is my EAZ?

Jens Ey jens@jeyhh.shnet.org wrote on 10 Jan 1997:

The EAZ for extensions is usually the last digit of the extension number. As EAZ for the Linux computer you should then enter a '6'.

26.6 What is a SPV?

SPV stands for "semipermanente Verbindung" (semipermanent connection) and is a (soon to be obsolete) specialty of the German Telekom. Like a leased line, the calling partner is fixed, however the connection is only established as needed (which occurs very quickly, much quicker that a dial connection). Since the Telekom can use the line for other things when it's not needed, the SPV is cheaper than a leased line.

This SPV is not to be confused with the Austrian understanding of SPV. The Austrian `SPV' has one channel leased line, and one channel for dialing.

26.7 How long will there still be SPVs?

Steffen Sledz sledz@dgroup.de wrote on 5 Dec 1996:

Due to a couple of lawsuits against the Telekom before the European Court of Justice, most likely until the end of 1997. This will be posted in the appropriate newsgroups and probably also at
http://www.birch.de (who is suing).

26.8 Does isdn4linux support SPVs? How?

To switch on the support for SPVs, add an "S" before the number to be dialed. This works (quite well) for modem emulations as well as for defined network interfaces.
