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.

n To 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.

n To 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


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 as close 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.

Dealing with RJ-11 connectors

On those models which equip with RJ-11 connectors. Use tools to fix the

RJ-11 jack on the wire that you are going to plug into the device

Dealing with IDC connectors

Note 2 It would be better to use 24AWG cable (such as CAT 5) for IDC

connectors.

1. Inserts the wires into the module jack without trim the rubber skin.

2. Press the crimp down to make the wire contact with IDC latch pins

and fasten it on the connectors.

3. Trim the rest of wire to prevent it short with other wires.

4. Plug in the module jack into the connector.

1.4.2 Console Port

For 12-inch and 19-inch models (Male, DTE connector)

For 7-inch desktop models

Use Null Modem cable to connect the console port on voice gateway and the serial

port of PC. You can refer to the Table 5-6 The Pinouts for Null Modem Cable Used on

Console Interface for more detail Pinout information.

1.4.3 CDR Port The CDR port equipped on some of the models only. Use the same null modem cable

as console interface and connect to the serial port on your billing system.

2.1.2 Wall Mounting 12-inch models

19-inch models

For wall-mounting, please be sure to have the FAN toward the upper side, for the heat

in the device will be easier to blow out from FAN with its side toward to the upper side.

Also please leave some space for air flow, this will help the heat dispatching. Below, is

a suggestion for wall mounting installation.

2.1.3 Desktop Mounting To put the device on the desk, it is better to stick on the rubber feet at the bottom of the

device to prevent the device slip away and also protecting the device from scratching.

2.1.4 Life-Line Application 2.1.4.1 Only work with MP3208

The life-line function is that when power fail and the device can not work, user still

have the ability to use local PSTN line to communicate with others.

Using MP3208 to take the life-line advantage.

Fig 18 Lines from PSTN connect to the FXO ports on MP3208 and lines from FXS ports of

MP3208 connect to the analog trunk ports of PBX

When power fail on VoIP gateway, the first port of FXS will be the last port of FXO on MP3208.

Thus, there is one to one port mapping of FXS with FXO ports on MP3208 module when power

fail.

2.1.4.2 The Lifeline support on 7-inches models On 7-inches models, the lifeline support work on port 1 (FXS) with port 2 (FXO) for 1FXS and 1

FXO model; for 2FXS and 2FXO model, lifeline works on port 2 (FXS) with port 3 (FXO).

2.1.4.3 Using MP3208 to save the extra Trunk card of PBX

Using MP3208 has another advantage that you can use your current analog trunk card without

add another new analog trunk card for PBX voice gateway. Although, you can have both

MP3008 and MP3108 to take the same advantage but with two modules instead of only one.
