ISDN settings
This section describes how to configure your unit to make calls over an ISDN
connection.
1. Navigate to the ISDN tab in the Adjust Communications Settings section of
the user interface and click the Enter button. Select the ISDN tab to display
the ISDN settings screen.
2. Select the ISDN switch type to which the unit is to be connected from the
Switch Type drop-down list.
3. Enter the local ISDN line numbers in Line 1 to Line 6 fields.
The number of ISDN numbers that you need to enter depends on how many
ISDN channels you are using. You need to enter two numbers for each of the
one, two, or three bonded telephone lines, in order to obtain 2B (128kbps),
4B (256kbps), and 6B (384kbps) bonded calls respectively.
For National ISDN 1 or DMS100, the full 10-digit number must be entered.
For other switches and localities, the area code should be omitted.
4. If the local ISDN switch is an ISDN-R 56K restricted network, select the
Restricted Network check box.
5. If you selected National ISDN 1 or Nortel DMS100 from the Switch Type
drop-down list, the SPID 1-6 button appears. Click it to open the SPIDs
screen (see Figure 5.6 on page 28). Select the Auto Detect SPIDs check box
(the unit detects your SPIDs automatically) unless you know that your
SPIDs are an unusual configuration; then enter them manually. If you
entered the ISDN numbers in the previous screen, you can click Auto Fill to
have them automatically transferred to the SPIDs number boxes. You will
need to reboot the unit to save these changes.

If you know that your
SPIDs are an unusual
configuration, deselect the
Auto Detect SPIDs check box and
enter the SPIDs manually in the
SPID fields.
✍
A bonded call uses special
hardware (IMUX) to bond
the ISDN lines into a
single logical channel. V-There can
dial bonded calls at rates of
128kbps, 192kbps, 256kbps and
384kbps. For a bonded call, you
must enter only a single destination
number when making a call.
✍
An unbonded call treats
multiple ISDN lines as
single channels. Each line
is 64kbps. You can dial a call with a
rate of 1x64kbps, 2x64kbps, and so
on, up to 6x64kbps. When making
an unbonded call, you need to enter
an ISDN number for each ISDN
line you are using.
✍
An ISDN-R call is
transmitted at a rate that
is a multiple of 56kbps.
This rate is used in some countries
where channel bandwidth is limited
to 56kbps. An ISDN-R call can also
be bonded.
