Introduction
Product Overview
The D-Link Analog Trunk Gateway DIV-140 is a full featured multi port SIP based VoIP gateway. It links traditional telephone network and
IP network. Using the DIV-140 you can explore the wide features of VoIP technology. It enables you to make and receive calls through a
low cost VoIP network using a conventional telephone network setup.
The advanced technology behind the DIV-140 presents a highly scalable and flexible architecture to cater to the needs of varied market
segments.
The highly flexible call routing settings allow the administrator to configure different routes for calls based on the dialed number. It provides
configuration to route all local PSTN numbers through PSTN lines and all long distance calls through different VoIP networks. Both, proxy
based calls and peer to peer calls, are supported simultaneously. It supports per port phone book and system phone book to place peer
to peer calls without going through a VoIP server.
It supports per port speed dial lists and system speed dial lists to enable quick dialing to frequently accessed numbers. Also various call
features can be individually configured for each port to different destinations.
With support to configure IP settings manually or use DHCP or PPPoE, the DIV-140 can work in different environments. Also, NTP is
supported with standard time zone configuration to keep the device time in sync with a server.
In VoIP server mode, each port can be configured with different account or the feature can be enabled to use same account for all ports.
With backup server configuration support, the device can still work in absence of primary server. The support for STUN and IP Sharing
enables the device to work behind NAT.
It provides secure web based management interface with administrative and restricted accesses to remotely configure and monitor the
system. The configuration backup facility helps in maintaining multiple configurations for the device.

Audio Configuration
Codec Priority:
Jitter Buffer Delay:
Packet Loss Rate:
Gain Settings:
Here you can select the priority of audio codecs. While
establishing a call, the DlV-140 will negotiate the highest
priority of codec acceptable to both parties. The administrator
can choose from four codecs. G.711 Mu and G.711 A provide
the best voice quality but consume the most bandwidth. G.723
consumes less bandwidth with some compromise on quality.
G.729 is a compromise between both. It uses significantly less
bandwidth as compared to G.711 and gives better quality as
compared to G.723.
The Jitter Buffer monitors network conditions and implements
a delay profiling algorithm that provides better tracking of
adaptive jitter buffer and improves voice quality.The jitter buffer
automatically determines the network jitter, maintains the
desired packet loss rate, subject to the limit of the maximum
allowed jitter delay. These parameters can be configured
here.
The Jitter Buffer Delay specifies the maximum desired jitter
delay in milliseconds. Range: 0 to 500 milliseconds. Default:
150 milliseconds.
Specifies the allowable packet loss rate in 0.1% units. Range:
0 to 50 (corresponding to 0.1 % to 5.0 %). Default: 1 (0.1%).
The volume settings at various levels can be configured here.
Here Tx field specifies stream going from this device to IP
network and Rx specifies the stream coming to this device
from the IP network.
VoIP: Increase this value to digitally amplify the signals.
Range: -40 dB to 15 dB. Default: 0 dB.
PSTN: Increase this value to amplify the signals at analog
level. Range: 0 or 1 (corresponding to 0 and 6 dB). Default: 0.
Tone: Modify this value to set the volume level of tones.
Range: -20 dB to 15 dB. Default: -12 dB.

In this mode of fax communication, G711 codec is used. Device will automatically switch to G711 codec on detection of FAX tone from the FAX
machine.
In this mode of fax communication, T.38 codec is used. Device will automatically switch to T.38 codec on detection FAX tone from the FAX machine.
If both the modes of fax communication are selected then preference will be given to Fax Relay mode. Following (FEC, Packet Redundancy Level,
and Ellipsis) are configurable parameters for Fax Relay features.
This feature can be selected to activate forward error correction in T.38 Fax Relay communication.
This feature can be selected to activate packet redundancy in T.38 Fax Relay communication.
This feature can be enabled to activate newer version of T.38 Fax protocol corrigendum 1. By enabling this feature, device will be able to work with
newer version fax devices.
The device cancels the echo generated by the hybrid of local telephone interface and phone set so that the other party connected to the channel
will not hear the echo. The parameters associated with echo cancellation can be configured here. Note: The default values should be good enough
for most cases and it is recommended that you don’t change it without assistance.
Echo Tail Length: This specifies the time span over which echo is expected to arrive.Tail length of 4 ~ 8 milliseconds is good enough for most cases.
Range: 2 to 64 in steps of 2 (corresponding to 1 to 32 milliseconds). Default: 36 (i.e. 18 milliseconds).
This is used to properly align the delayed signal with reference signal. Range: 0 to 240 (corresponding to 0 to 30 milliseconds). Default: 0 (i.e. 0
milliseconds).
When this is enabled, the DIV-140 detects a silence interval and uses silence compression to save on bandwidth. This feature works irrespective
of the codec selected. Default: Enabled.
There are four modes in which DTMF can be transmitted.
• In Band Mode
• Out Of Band Mode
• Info Mode
• Auto Mode.
In In Band Mode, DTMF packets are sent in band. In Out Of Band Mode, DTMF packets are sent as RTP Packets with different payload type as
configured in DTMF Payload field. In Info Mode, DTMF packets are sent as SIP INFO Packets and in Auto Mode the mode of DTMF transmission
is selected automatically to In Band, Out Of Band or Info according to the remote ends capability. Default: Auto Mode.
