System Description
nel). The inputs have separate digital Sample Rate Converters (SRC). For syn-
chronisation with an external clock a clock input and a clock output are avail-
able.
Two separate PRETALK interfaces are available in all three operating modes.
Two Telephone Handsets or Headsets (Options: ID: 802003/802004) can be
connected for Pretalk. In the POTS operating mode you can connect two
standard POTS Telephones for dialling and Pretalk.
The advantage of a handset/headset over a POTS Telephone is the possibility
to switch between ON AIR and PRETALK anytime. With a telephone con-
nected to the hybrid, it is only possible after the caller has been switched to
ON AIR and if the telephone has not been hung up.
MAGIC TH2plus can be operated primarily via the front keypad and the illu-
minated display.
The configuration and operation is especially comfortable via the MAGIC
TH2plus Software (see CHAPTER 5) included in delivery, which communi-
cates with the system via the LAN interface. You can install up to three PC
workplaces (additional MAGIC TH2plus Software Licences required, ID:
430396).
Most basic operating functions like accepting a call, dropping a connection
and establishing a connection with a pre-programmed number can be carried
out via four programmable TTL contacts. Two relays are available for status
indication.
Additionally, the operation can be carried out via up to two MAGIC TH2 Key-
pads (see CHAPTER 7) which can be connected to the RS232 interface.
