to expire after a number of seconds have passed without any data traffic. If you set this timer
to zero, then the ISDN connection will never be disconnected.
The 2
nd
ISDN bearer channel (B2 channel) may either be enabled or disabled. We recommend
that the OmniConnect/ISDN series access device dynamically use the B2 or 2
nd
channel by
selecting the
Dynamically
check box. If, however, the 2
nd
ISDN channel is never to be used,
it may be disabled by selecting the
Never
check box. When the
Never
check box is selected,
the OmniConnect access device will not enable the B2 channel (even when the traffic
conditions require it to use the 2
nd
ISDN channel). The 2
nd
ISDN channel may be enabled, on
a permanent basis, by selecting the
Always
check box. This forces access device to dial using
both ISDN channels all the time. Both the B1 and B2 channels will always be connected when
this option is selected.
The
ISDN Channel Speed
parameter is used to set the rate at which ISDN data calls are
connected to the ISP. Voice calls are always connected at 64 KBPS regardless of the setting
of this parameter. Use the check boxes to choose between
Auto
,
64 KBPS
or
56 KBPS
.
When
Auto
is chosen, connections to the ISP are attempted at 64 KBPS and then in most
instances retried at 56 KBPS. There are certain circumstances in which 56 KBPS connections
are not attempted and therefore 56 KBPS connections may not complete when set to
Auto
. In
these cases, the parameter should be set to 56 KBPS.
The
Analog Phone Setup
configuration option is used to control the flow of analog calls.
Incoming and outgoing analog calls may be allowed or prohibited by either selecting the
Allow Analog Calls
or
Disable Analog Calls
setup options. If the
Allow Analog Calls
option is selected, the ISDN Channel (B1 or B2) may be further specified to carry the analog
call. The
Auto
selection lets the OmniConnect access device decide which ISDN channel to
use for analog calls based on the traffic patterns and usage. This, however, can be forced to a
certain ISDN channel for voice calls by selecting
B1
or
B2
channel.
Finally, the Digital Voice Coding parameter sets the voice-coding standard used to
communicate with the Central Office switch during voice telephone calls. In North America
and Taiwan a type of PCM encoding known as
µ
law is used. In Europe and Asia, A-law PCM
encoding is used. Choose the correct encoding for the area in which the OmniConnect/ISDN
is being used.

ISDN Caller ID directory setup
The ISDN Caller ID
Directory Setup screen
is used to add, edit and
remove ISDN Caller

information that is
received during an
incoming call is
displayed by the

addition, Caller ID
information is used by
the OmniConnect
access device to
