10.8 Hybrid in/output card
Table 10-8 Hybrid Rj14 (Telephone) connection
This Hybrid In/output card converts the analog telephone signals into digital audio so it
can be processed by the 19” inch rack.
The Hybrid card
allows external callers to be connected to the AXUM. A connection can
be established via the start/stop function in the engine.
If a local phone is connected, it is possible to originate a call to a remote side. If no local
phone is present, someone at a remote site must call you.
