Incoming Interdigit Service
The
Incoming Interdigit Service
is used to configure E1/T1 dial plan for the incoming calls from CO/PBX to the QX. This service allows you to speed up
the call establishment procedure by detecting the prefix. The calls will be speed up by the timeout defined in the
Incoming Digits Timeout
text field.
When the system detects incoming dialed number starting with any
of the prefixes listed in the
Incoming Interdigit Service
table, it will
wait for the rest of the digits, as specified for the corresponding
prefix in the
Incoming DNIS Size
text field (see below). Once all
digits are received, the system will route the call to the destination.
The
Incoming Interdigit Service
page lists a table with existing
E1/T1 dial plan entries and allows you to manage them.
By default, the table on the
Incoming Interdigit Service
page lists
the locale specific (selected from the
E1/T1 dial plan settings. For some countries, this table may however
be empty.

Add
functional button leads to the
Add Entry
page where a new
E1/T1 dial plan entry can be configured.
The
Add Entry
page consists of the following fields:
The
Incoming DNIS Prefix
text field requires the prefix of the
incoming dialed number. '[' , ']' , ',', '-', are used to define a range or
a quantity of prefixes. For example, 2[5-9] means that the prefix of
the dialed number may be 25, 26, 27, 28, or 29. 3[4,7,0] means that
the prefix of the dialed number may be 34, 37 or 30. Only one range
of prefixes can be defined in the
Incoming DNIS Prefix
text field.
Fig.II- 53: Incoming Interdigit Service – Add Entry page
The
Incoming DNIS Size
text field requires the total length of the dialed number, including the prefix digits. The number defined in this field should be
greater than the longest prefix defined in the
Incoming DNIS Prefix
text field, otherwise the error message will appear.
The
Description
text field requires an optional description for an E1/T1 dial plan entry.
The
Restore Default Settings
functional button is used to restore the locale specific E1/T1 dial plan entries
ISDN Settings
The
Integrated Services Digital Network
(ISDN)
is distinguished by digital telephony and data-transport services offered by regional telephone carriers.
ISDN involves the digitization of the telephone network, which permits voice, data, text, graphics, music, video, and other source material to be
transmitted over existing telephone wires. The ISDN Basic Rate Interface (BRI) service offers two B channels (voice transfer) and one D channel (signaling
data transfer). The BRI B-channel service operates at 64 kbit/s and is meant to carry user data. The BRI D-channel service operates at 16 kbit/s and is
meant to carry control and signaling information, although it can support user data transmission under certain circumstances.
The
ISDN service
allows QXISDN4 gateway act as a user or as a network. If connected to a private PBX, the QXISDN4 should be configured in the network
mode. If an ISDN trunk from the CO (Central Office) is connected to the QXISDN4, it should be configured as a user.
QXISDN4 supports the MSN (Multiple
Subscriber Number) service, i.e., it can be subscribed to multiple numbers from the CO, and two simultaneous calls can take place at a time.
The
ISDN Trunk Settings
page is used to configure the ISDN trunk and their signaling. There are 4 ISDN trunks available on the QXISDN4 gateway.
The
Trunk Settings
table lists the available ISDN trunks on the QXISDN4 and their settings (trunk name and interface types).
The
Start
and
Stop
functional links are used to start/shutdown the
selected ISDN trunk(s). When an ISDN trunk is in a shutdown
state, ISDN calls cannot be placed or received.
The
Restart
functional link is used to bring channel(s) to the initial
idle state on both sides. When applying one of these options, any
active traffic on the channel(s) will be terminated.
The
Copy to Trunk(s)
functional link displays a page used to
choose a trunk to which selected trunk’s settings should be copied
to.
The
Restore Default Settings
functional link restores the default
signaling settings of the selected ISDN trunk(s).
Fig.II- 54: ISDN Trunk Settings page
Clicking on the corresponding ISDN trunk will lead to the
ISDN wizard
where trunk’s ISDN signaling settings can be configured. The
ISDN Wizard
consists of several pages.
The
ISDN Wizard
–
ISDN Settings
allows you to choose the interface type and the connection type of the selected trunk(s).
