26. 1tr6: German Pecularities for 1TR6

26.1 1tr6{[lowbar]}eaz: 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.

26.2 1tr6{[lowbar]}extension: 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'.

26.3 1tr6{[lowbar]}spv: What is a SPV?

SPV stands for {[quot ]}semipermanente Verbindung{[quot ]} (semipermanent connection) and is a (soon to be obsolete) speciality 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.

26.4 1tr6{[lowbar]}spvdial: Does isdn4linux support SPVs? How?

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