Analogue down-circuit connection

With an analogue down-circuit connection the features of the up-circuit PBX can
also be utilized.
This results in the following special applications for the user:
• Depending on the system configuration the user makes phone calls in a com-
plex PBX environment. The subscriber's disposal is a large number of features at
two levels (subscriber's own system and the up-circuit system). A short induc-
tion course helps users to familiarize themselves quickly with the PBX environ-
ment.
• Practically all PBX types that can be used as an up-circuit PBX also feature the
DTMF dialling method on the analogue terminal line, in addition to pulse dial-
ling. It is advisable to give preference to the DTMF dialling method over pulse di-
alling.
• If the up-circuit PBX requires that subscribers wait for the exchange-free tone, all
the entered abbreviated dialling numbers must be provided with a hyphen "-"
(interdigit pause) after the digits for exchange access. At this point the PBX will
again pause for the tone when dialling.
