1 Overview
1.1 Product Introduction
MX Series intelligent VoIP Gateways (hereinafter called MX Gateways or simply Gateways) are
designed for bridging the traditional telecom terminal devics 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 Gateways are suitable for placement on office desktops or installation on walls in the corridor and
racks in the equipment room.
MX Series includes MX8, MX60, MX100 and MX120 subseries. Their features are similar with the main
differences as follows:

MX Gateways use Freescale® PowerQUICC communications processors as main control processors
(including 50MHz MPC852T, 200MHz MPC8250 and 300MHz MPC8247) and TI’s TMS320VC5509A
high-performance digital signal processing chips as processors for voice and fax processing (equipped
with 1-12 DSP chips based on the need of concurrent call capacity), and are integrated with 32MB-64MB
SDRAM as system memory, 4MB-16MB FLASH as permanent file system. The powerful processing
capability and sufficient hardware configuration ensure that all products of MX Series can provide
concurrent calls of full capacity and maintain good call quality.
All MX Gateways run on stable and reliable embedded Linux operating system. On top of Linux OS, the
driver layer handles hardware specific control in different product platforms. This makes single source

UserManual MXVoice-FaxGatewaySeries

(FSK/DTMF), call transfer, call waiting, call hold, call barring, caller ID restriction, hotline, corporate
CRBT, three-way calling, ring group, fax and etc;
FXO related functions such as PSTN failover, gain control, busy tone detection, voice prompt in
inbound calls, polarity reversal detection;
Media stream processing functions such as RTP redundancy, packet loss compensation,
G.711/G.729A/G.723.1/iLBC/GSM voice codec, echo cancellation, and etc.
MX Gateways support local and remote, distributed and centralized management modes, including Web
access management, command line configuration based on Linux OS, auto-provision for firmware

Do not plug and remove the interface cards of MX120 when equipment is powered on.
Numbering definition of system interface slots: On the left side of main chassis is #1 slot (marked with
No.1 to 24), on the right side of main chassis is #2 slot (marked with No.25 to 48).
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 and caller ID transmission of FXS interface, ringing, offhook and caller ID detection
of FXO interface) 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 equipped 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 to the Appendix: Check List for Operation
Status Indication of MX120 System.
