Installation Connectible Devices
a/b Ports
The a/b ports a/b1 to a/b4 can be
used for connecting analogue termi-
nals. These can be for voice or data
communication, and use DTMF or
pulse dialling, e.g.
■
analogue telephones
■
class 3 fax machines
■
analogue modems (external or
internal)
■
external devices for music on
hold
■
external voice mail systems.
Please note: Adhere to the fol-
lowing notes and recommendations
regarding the connection of ana-
logue devices. Devices not meeting
the technical requirements of the
OpenCom 100 can cause damage to
it.
Analogue Telephones
If analogue telephones are to be
used, we recommend the use of de-
vices featuring voice-frequency (VF)
signalling, as the additional features
of the OpenCom 100 cannot be used
with pulse dialling.
Modems
The maximum transmission rate for
analogue modems is 33.6 kbit/s
(V.34+).
Music on Hold
A suitable external device for music
on hold is the Genius 2000, manu-
factured by Speech Design. If you do
not operate an external MoH device,
the Access 5000 offers an internal
MoH, which you can load in the Web
console
Configurator , SYS Configu-
ration: Components menu. For de-
tails, refer to the online Help.
Please note: Use only devices
with an input impedance of
600 ohms, floating connection, for
external music on hold. Incorrect in-
put impedance can cause irreparable
damage to the OpenCom 100.
Voice Mail
If you are using an external voice
mail system, it must be capable of
handling the number of digits used
for internal telephone numbers, e.g.
five digits if you have configured
five-digit internal numbers. We rec-
ommend the following Speech De-
sign products: Memo 200/300/400
or Memo 200-A/300-A/400-A.
The external voice mail system can
be connected to internal a/b ports as
well as to internal S
0
ports. For both
port types the voice mail system can
activate the notification for system
terminals with the code procedures
* 6 8 resp. # 6 8 .
