IDM RG3200

1. Overview

The IDM RG3200-PX is a media trunking gateway independently developed and manufactured by Raytrans to meet the voice service requirements of enterprises/industries and carriers. This gateway is positioned at the interface between the Public Switched Telephone Network (PSTN) and IP networks, implementing protocol conversion between signaling protocols such as SS7 (TUP\ISUP), ISDN PRI, V5.2, R2, Q.SIG and the VoIP SIP protocol, while also completing media stream conversion between the bearer channels of the PSTN and IP networks. A single unit supports up to 16 E1 links and up to 120 concurrent SIP sessions.

The IDM RG3200-PX employs advanced software and hardware technologies with carrier-class design, ensuring high reliability of the equipment. The system utilizes mature high-performance CPUs and DSPs, along with an embedded real-time operating system and efficient algorithms, delivering exceptional performance.

2. Product Features

2.1 Superior Voice Communication Quality

• Based on powerful processing capabilities, the IDM RG3200-PX achieves excellent voice communication quality;
• Voice Activity Detection (VAD) technology effectively conserves bandwidth resources;
• Comfort Noise Generation (CNG) technology provides a call experience identical to that of the PSTN;
• Adaptive dynamic buffering technology meets the requirements of demanding network environments;
• Maximum G.168 128ms echo cancellation technology, far exceeding the specifications of comparable gateways, eliminates echo interference caused by long-distance calls;
• DTMF detection/generation technology effectively supports services such as fax, call-back, and secondary dialing.

2.2 Rich Service Features

• Calling/Called party number translation;
• Supports registration as a terminal to other GK or SIP servers for trunking functions;
• Supports operation as a GW device controlled by an upper-level GK/SS to complete trunk calls;
• Supports interworking between any of SIP/SS7/PRI/R2/V5.2/Q.SIG;
• Supports automatic routing;
• Supports large-capacity black/white lists;
• Supports SS7 calling party number hiding;
• Supports simultaneous registration to 4 SIP servers;
• Supports CDR output;
• Fax support: T30, T38, and transparent transmission;
• Supports call forwarding number extraction, i.e., original calling party, original called party, and forwarded number;
• Supports hunting group functionality;
• Supports calling party number detection and Caller ID;
• Supports generation of dial tone, ringback tone, etc.;
• Port gain and comfort noise are adjustable.

2.3 Simple and Convenient Management and Maintenance

• In software, the IDM RG3200-PX supports configuration and network management via WEB, TELNET, and SNMP, allowing non-professionals to easily manage and maintain the device;
• In hardware, the IDM RG3200-PX features a compact design, only 1U high, and can be installed in a 19-inch standard rack or independently in a small equipment room.
