Incoming Interdigit Service
The
Incoming Interdigit Service
is used to configure E1/T1 dial
plan for the incoming calls from CO/PBX to the Quadro. 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
System Configuration
Wizard
) 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.

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 Quadro act as a user or as a network. If connected to a private PBX, the Quadro should be configured in the network
mode. If an ISDN trunk from the CO (Central Office) is connected to the Quadro, it should be configured as a user.
Quadro 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 QuadroM 12Li/26xi has six ISDN trunks. For QuadroM 32x/8L/26x/12Li/26xi the shared ISDN trunks are displayed in this page, if available. The
shared trunks can be edited from ISDN setting page. Any changes applied in that page will be automatically reflected on the ISDN gateway(s) that
share its ISDN trunks.
The
ISDN Trunk Settings
page is used to configure the ISDN trunk and their signaling. This page offers the following input options:
The
Trunk Settings
table lists the available ISDN trunks on the Quadro and their settings (trunk name and interface types).
