the user still have the ability to access to the PSTN that connected with FXO interfaces from
FXS interfaces.

1.2 Panel Outlooks
The VoIP Gateway series have three main streams, one is 12-inch wide series,
19-inch wide series and the other is 7-inch size desktop model. 12 inch wide series
have fixed port number and FXS interfaces only, the 19-inch wide series are
modularized design and 7-inch size desktop models are designed for small port
density or portable usage.
1.2.1 Front Panels
On the front panels of VoIP gateway, there are two Ethernet Ports, RS-232 Console
ports and status LEDs. If Call Detail Record is provided, it has extra CDR (Call Detail
Record) port.
On the front panel of 12-inch and 19-inch models, the markings of port numbers are
associated with port number 1 to 4 and group number. This is a logical representation
that design for management interface like Web management interface, Command
Line Interface. In those user interfaces the first port will be "1/1" means the port 1 of
group 1, "1/4" means the fourth port of the device and "4/4" means the last port. For
desktop models, the port numbers do not need to specify the group number, just 1 for
port one, 2 for port two and so on.

1.2.2 Rear Panels
All the voice interfaces connectors are located at the rear panel for 12-inch and
desktop 7-inch models. And also the DC power-in jack is located on the rear panel
too.
There is a press button at the rear panel for all VoIP gateways. It is for special
maintenance purpose does not press it in normal usage.

1.3 LAN Interfaces
The two Ethernet Ports on PBX voice gateway have different priorities. The "To WAN"
port has higher priority than the "To LAN" port. This is going to provide the incoming
voice stream from WAN port can be received prior the data on the local area network.
Both "To WAN" and "To LAN" Ethernet ports are 10/100Mbps, Half/Full-duplex
auto-negotiable. Users do not need to configure the speed or mode for Ethernet
connection.
nTo connect to the router on the WAN port side, user can use Straight-Through
RJ-45 cable to connect the MDI-X on the PBX voice gateway with the MDI port
on the router.
nTo connect the "To LAN" port the Hub or Switching Hub on local area network,
user can use Straight-Through RJ-45 cable connect to the MDI-II (Up-link) port
on Hub or Switching Hub.

1.3.1 QoS Configuration

VoIP Gateway Hardware Installation Guide
Page 9/9
DOC No.: 9172000302
Since Ethernet is under CSMA/CD mechanism, to provide the QoS for voice packet
over Ethernet interface, it is need to place the voice gateway as near to the router as
possible. With internal hardware QoS facility, the voice packets will have higher
priority than data from local area network.
Fig 15 Diagram to provide QoS for voice packets in LAN
1.3.2 Cascading Devices
Fig 16 Diagram to provide QoS for voice packets in LAN by cascading voice gateways
Base on the same principal to have voice gateway asclose to the router as possible in
network connections, the voice packets will still have higher priority than data from
local area network.

1.4 Connectors
1.4.1 Voice Ports
WARNING: Before plugging the connectors into the FXS interfaces on PBX
voice gateway do check if the lines that are going to plug into do not have any power
source ("0" voltage).
Seizure Sequence
The PBX voice gateways are designed for Auto-Hunting of free voice ports. The seizure
sequence are as follows; that the FXS ports are seized from lower port numbers to higher port
numbers. And the FXO ports are seized from higher ports to lower ports.
The principal of utilizing the seizure sequence is to prevent over exult on using some certain
ports to balance the available life times of the device. So if the PBX seize the trunk lines from 1
to 8, then we might connect the line1 of PBX analog trunk to the FXS port 8 on the voice
gateway. Thus when user seizure the analog trunk it will start to connect to the FXS ports on
voice gateway from port 8 to port 1, mean while, that receiving a remote call will utilize ports
start from port 1 to port 8. This will reduce the number of collisions of seizing the channels also.
Base on the same philosophy, if the incoming calls from PSTN (Central Office) start from phone
number 508-1201 to 508-1208 (where the main office number is 5081200), then it would be
better for us to connect the phone line with number 5081201 to the port 1 of FXO on voice
gateway.
