DHCP Server
When using the DHCP feature, the IP address settings of the card (IP address, subnet mask,
and default gateway) will be assigned by a DHCP server.
However, keep in mind that the maintenance of the card is performed through a web browser
from a PC; hence you must know the IP address of the card. Therefore, it is necessary to set
up the DHCP server to assign a static IP address to the card from a pool of IP addresses that
is defined in advance. For more information about DHCP server settings, consult your network
administrator.
In addition, it is also necessary to specify the values for the parameters under "IP Address
Settings" as they will be assigned by the DHCP server.
Parameter & Description Default Value Range
#HTTP Port No.

Detailed Explanations
Gatekeeper
The following are the general functions of a gatekeeper:
•Dialed number-to-IP address translation
•Authentication
•Bandwidth control
It is possible to employ a VoIP network without the use of a gatekeeper, because the card is
equipped with internal address translation capabilities. However, should the network contain
dozens of cards, maintenance of address translation tables in individual cards can become a
strain.
A gatekeeper is useful in this case, because with the gatekeeper it is possible to consolidate
the maintenance. (However, you still need to program each card on the network with its own
address translation information. For details, refer to "2.2.6 Address Translation Table—GW
Entry" and "2.2.7 Address Translation Table—DN2IP Entry".) For more information about
gatekeeper functions, consult the documentation of the gatekeeper.
When using a gatekeeper, make sure to choose a compatible model. For more information
about gatekeeper compatibility with the card, consult a certified dealer.
*Gatekeeper Connection Checking Interval
(min) 0-1440min
Specifies the time (in minutes) between periodic
checks of connection to the gatekeeper.
When the primary gatekeeper fails, these checks can
detect the failure. In this case, the connection
automatically switches to the secondary gatekeeper if
it is available, so that the network remains functional.
00(disable),
1 to 1440
*Call Signaling Model
Specifies whether to carry out a call control (H.225)
process directly between the cards or through a
gatekeeper.
Direct call control is typically preferred because it
involves less network load.
Direct Direct,
Routed (via
Gatekeeper)

The parameters below are used to set the ToS (Type of Service) field in the header of IP packets to
control QoS of VoIP communications.
For more information about QoS, refer to "A1.4 QoS (Quality of Service)" of the VoIP Gateway Card
Getting Started. For the actual setting values, consult your network administrator.

When voice signals are packetized and transmitted, individual packets can take different paths through
the network and arrive at the destination at varied timings. This is referred to as "jitter", and it can cause
degradation in speech quality. To compensate for jitter problems, the "jitter buffer" accumulates the
packets temporarily for processing.
The parameters below are used to adjust the size of the jitter buffer; however, in general, there is no
need to change the default values.
Parameter Default Value Range
G.711/G.729A Jitter Buffer Minimum (ms) 10 10 ×n (n = 1–40)
G.711/G.729A Jitter Buffer Maximum (ms) 400 10 ×n (n = 1–40)
