1 TR 6 did not support Multiple Subscriber Number s but featured an ''Endgeräteausscheidungsziffer'' (''EAZ'', German "user device selection digit"). ISDN subscribers would get a sequence of 10 subsequent subscriber numbers, the last digit of which being the EAZ. The EAZ "0" was used for "global calls" to all connected devices. 1 TR 6 also offered ''semipermanent connections'', which were (comparatively cheap) Leased Line s that could be temporarily disabled to use the B Channel for other purposes. It is said that the "TR" simply stands for "technische Richtlinie" (technical guideline). |
