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;
To bridge the traditional telecom terminal equipment, such as PBXs, to the VoIP core networks of
carriers;
To connect with an enterprise PBX to provide IP-based voice private network solutions for
institutions, enterprises and schools;
To be used as remote access equipment for IP-PBXs in call center deployment
The MX family has four sub-series: HX4E, MX8A, MX60, MX60E and MX120G, which mainly differ in
port capacities.

MX Series Voice Gateway User Manual
New Rock Technologies, Inc. 15
Hardware for MX series gateways uses high-performance CPUs, ensuring 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),
implementing scores of business phone functions, including: call forwarding, call transfer, call hold,
teleconference, caller identification, Do Not Disturb, ring-back 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, phone digit
manipulation, and PSTN failover upon power-off or network disconnection.
MX gateways support local and remote management operations through Web GUI or SSH, SNMPv2-
based and TR069/TR104/TR106-based centralized management schemes, and auto provisioning.
Maintenance tasks such as modifying configuration, upgrading software, collecting statistical data,
downloading logs, and fault alarms can be performed.
Note: PSTN failover upon power-off or network disconnection is supported by devices with both the FXS
port and the FXO port.
1.2 Functions and Features
Connect analog telephone, PBX, facsimile machine and POS machine to the IP core network, or
PSTN
Work with a service platform to provide various telephone supplementary services
Support protocols: SIP, MGCP
Support STUN. Detecting changes of the reflexive address of the device via STUN, and then
triggering re-registration to the SIP registrar server.
Flexible configuration of subscriber/trunk interfaces
Support G.711, G.729
Support echo cancellation
Up to 500 routing rules can be stored in gateways
Intercom
