1 Overview
1.1 Product Introduction
MX Series intelligent VoIP Gateways (MX Gateways) are designed to bridge the traditional telecom
terminal device into IP networks through SIP or MGCP protocols. The main applications include:
For carriers and value-added service providers to provide telephone, fax and voice-band data services to
subscribers using IP access methods such as FTTB, HFC, and ADSL;
Used to bridge the traditional telecom terminal equipments, such as PBXs, to the IP core networks of
carriers;
Connected with PBX of enterprises to provide IP-based voice private network solutions for institutions,
enterprises and schools;
Used as remote acces equipments for IP-PBXs in call center deployment.
MX Series includes MX8, MX60and MX120 subseries. Their features are similar with the main
differences as follows:

Hardware of MX series gateways use high-performance CPUs, ensure that each product of the series
can achieve full-capacity concurrent calls with high speech quality.
MX gateways software adopts the stable and reliable embedded Linux operating system (OS), thereby
implementing scores of business phone functions, including, call forwarding, call transfer, call hold,
teleconference, caller identification, Do Not Disturb, ringback tone, hunt group simultaneous ring,
distinctive ring, one phone with two numbers, and fax. In addition, MX gateways are featured with
FXO port second stage dialing with voice prompt, routing table with a maximum of 500 entries, pone
digit manipulation, and PSTN failover upon power-off or network disconnection.
MX gateways support local and remote management operations through Web GUI or Telnet and also
support SNMPv2-based and TR069/TR104/TR106-based centralized management scheme.
Maintenance tasks such as modifying configuration, upgrading software, collecting statistical data,
downloading logs, and fault alarms can be performed.

Matrix of 6x4 LED status indicator on interface card
②③④⑤
Four interface slots; each can contain one 24-port interface card.
Do not plug and remove the interface cards of MX120 when equipment is powered on.
Numbering definition of system interface slots: on the low-left side of chassis is #1 slot (marked with
No.1 to 24), on the low-right side of chassis is #2 slot (marked with No.25 to 48), on the up-left side of
chassis is #3 slot (marked with No.49 to 72), and on the up-right side of chassis is #4 slot (marked with
No.73 to 96).
Each RJ45 socket has 8 pins leading out 4 pairs of analog telephone or trunk lines in agreement with the
pair specifications for Ethernet interfaces, whose corresponding relations can be seen in the table below.
CAT-5 cables are used to connect the interface card and distribution panel in equipment installation.

Standard RJ11 telephone lines can be used to plug in a RJ45 socket. The telephone/trunk lines are
connected to the 3rd pair of pins for simple call test.

There is a 6 ×4 LED indicator matrixes on the left side of interface board. Each row of LED indicator
matrixes matches four telephone lines on a RJ45. The first row on the left matches Line 1-4
respectively from top to bottom, the first row on the right matches Line 21-24 respectively from top to
bottom, and the middle rows in the same manner.
LED indicators are used for multiple purposes as follows
Line status indication: this is the most common mode during normal use of equipment. In this mode, if a
line is idle, the indicator corresponding to it goes off; if a line is in call or in use status (such as ringing,
offhook) the indicator corresponding to it goes on.
Line type indication: this is the mode for cable wiring check when installing the equipment. This mode
can be entered by disconnecting Ethernet cables (Both WAN and LAN ports must be disconnected) at
installation stage. After entering this mode, steady on LED indicates that the corresponding line is

equipped as analog subscriber line type, flashing LED indicates that the corresponding line is
equipped as analog foreigh exchange line type, off LED indicates that the corresponding line is not
equpped or not ready for use.
System operation status indication: this is the mode for displaying information on system operation of
equipment in specific conditions. Usually, this mode is entered when some prompts are required to
give operator during equipment startup, diagnosis or operation. In this mode, LED flashes to display
numbers, letters or other patterns in matrix. Please refer toTable 1-18.

The gateway is in progress of system software upgrade. Please guarantee stable power supply and
do not conduct other operations during this period.

2 Parameter Setting
2.1 Login
2.1.1 Obtaining Gateway IP Address
Differ from medium- and large-scale Gateways, MX8 Gateways start DHCP service by default, and
automatically obtain an IP address on the LAN; users can use the factory-default gateway IP address if
it is unable to be obtained (e.g. when connected directly with a computer).
MX60 and MX120 Gateways use a static IP address by default.

DHCP Used in Network
Users can dial ## to obtain the current gateway IP address and version information of firmware using
the telephone connected to the subscriber line (FXS ports) after the equipment is powered on.
If the gateways are only configured with FXO ports for analog trunks without FXS ports for subscriber
lines (e.g. MX8-4FXO), users can dial into the gateway by connecting a PBX extension line or PSTN
POTS line to a FXO port, and press ## to obtain the current gateway IP address and version
information of firmware after receiving the second dial tone.
Note: The access mode of the FXO port must be configured as second stage dialing mode. For details,
see section 2.5.4 Trunk Line Features.
Fixed IP Address Used
If the DHCP service on the network is not available or the gateway is directly connected with a computer,
the gateways will use the factory-default IP address.
A user could fail to log in with the default IP address if the IP address of user’s computer and the default
gateway IP address are not at the same network segment. It is recommended that the IP address of
user's computer is changed to be identical with the same network segment of the gateway. For
example, if the gateway IP address is 192.168.2.218, it is recommended to set the computer’s IP
address to any address at the network segment of 192.168.2.XXX).
PPPoE Used
In Basic > Network, the gateways will automatically obtain the WAN address returned by the access
network after the PPPoE service is started and the user name and password are set. Users can dial ## on
