All the features of Ascotel remain available.
4.5.6.1 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 subscriber:
• Depending on the system configuration the subscriber makes phone calls in a
complex PBX environment. The subscriber’s disposal is a large number of fea-
tures at two levels (subscriber’s own system and the up-circuit system). A short
induction course helps subscribers to familiarize themselves quickly with the
PBX environment.
• Practically all PBX types that can be used as an up-circuit PBX also feature the
DTMF dialling method on the analogue subscriber line, in addition to pulse dial-
ling. To prevent faulty dialling, the DTMF method should be used whenever
possible.
• 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.
