1 Overview
1.1 Product Introduction
RGW Series intelligent VoIP Gateways (RGW 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 RGWfamily has four sub-series: RGW4, RGW8,RGW48, and RGW96, which mainly differ in
port capacities.

User Manual RGW Series VoIP Gateway
12 Redstone Systems, Inc.
Hardware for RGW series gateways uses high-performance CPUs, ensuring that each product of the
series can achieve full-capacity concurrent calls with high speech quality.
RGW 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, RGW 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.
RGW gateways support local and remote management operations through Web GUI or SSH,
SNMPv2-based and TR069/TR104/TR106-based centralized management schemes, andauto
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 disconnectionis 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
Support concurrent calls under full load
Support call progress tones for various countries and regions
Support Line second stage dialing or voice prompt
Support PSTN failover on power or network failure
Security strategy: IP filter, encryption
Support PSTN failover through FXO ports
Support G.711 fax pass-through and T.38 fax relay
Support polarity inverse detection and busy tone detection
3-way calling
Compatible with unified communication solutions, such as CallManager, Lync,Asterisk and
FreeSWITCH
Support SNMPv2 and TR069/TR104/TR106

The PC port is used to connect a computer.
The WAN port is used to connect the uplink network.
Both are 10/100 Mbps Ethernet ports (RJ45). They share one IP address, which, by default, is obtained
through DHCP. If no IP address is obtained, 192.168.2.218 is used by default, and you can change it on

CON
The console port is used for local management and testing. PCs can be connected to device by linking
the RS232 port to CON port.
Connecting cables need to be produced or purchased.
If the connection is established between the device and the mobile PC with no RS232 ports, please use
the cable together with a USB to an RS232 converter cable.
Cables are shown below in Figure 1-5 and Figure 1-6.
PC/WAN
The PC port is used to connect a computer.
The WAN port is used to connect the uplink network.
Both are 10/100 Mbps Ethernet ports (RJ45). They share one IP address, which, by default, is obtained
through DHCP. If no IP address is obtained, 192.168.2.218 is used by default, and you can change it on

Remarks
Each interface slot has four RJ45 sockets; each RJ45 socket corresponds with four pairs of analog
lines. CAT-5 cables are used to connect the interface card and distribution panel in equipment
installation. For corresponding relations of RJ45 and RJ11, see 7 Appendix: RJ45 and
RJ11Corresponding Relations.
Note: Numbers of interface slots vary from different configuration. Numbering definition of interface
slots: on the left side of chassis is #1 slot (marked with No.1 to 16), in the middle of chassis is #2 slot
(marked with No.17 to 32), on the right side of chassis is #3 slot (marked with No.33 to 48).
Matrix of 4 x 4 LED status indicators on the interface card. Each column of LED indicator matrix
matches four telephone lines on a RJ45. The first column on the left matches Line 1-4 respectively
from top to bottom, the first column on the right matches Line 13-16 respectively from top to bottom,
and the middle columns in the same manner.
