Technical Specifications

Overview & High-Availability Features

  • The MTG2000B is a carrier-grade, high-availability (HA) digital VoIP gateway equipped with redundant main control units (MCUs) and dual power supplies for exceptional reliability.

  • It supports 4 to 16 E1/T1 ports (in a compact 1U rack-mount chassis), making it highly scalable for growing infrastructure needs.

  • Capable of handling up to 480 simultaneous calls, it’s suitable for large enterprises, telecom operators, call centers, and service providers.

Voice & PSTN Protocol Support

  • Supports a wide range of PSTN signaling protocols, including ISDN PRI, SS7 (with link redundancy), and R2 MFC, enabling seamless interconnection between traditional networks and SIP-based VoIP systems.

  • Comprehensive fax and modem support: T.38 fax, pass-through fax, and compatibility with modem/POS systems for legacy integrations.

Voice Codecs & Quality Enhancement

  • Audio codecs supported: G.711 (A/μ law), G.723.1, G.729A/B, iLBC (13k/15k), and AMR.

  • Incorporates voice quality features such as echo cancellation (G.168, up to 128 ms), silence suppression, comfort noise generation (CNG), voice activity detection (VAD), adaptive jitter buffering, and gain control for both voice and fax.

SIP Capabilities & Network Features

  • Supports SIP v2.0, SIP-T, and related protocols (RFC3372, RFC3204, RFC3398). It allows for multiple SIP trunks and supports up to 256 SIP/IMS accounts for extensive integration.

  • Includes network features like NAT traversal (Dynamic NAT, Rport), adaptive dynamic buffering, and encryption (voxel – VOS RC4) to secure signaling and media.

Routing & Intelligent Call Control

  • Enables flexible routing modes: PSTN-PSTN, PSTN-IP, and IP-PSTN.

  • Highly intelligent call routing—including time-based logic, prefix manipulation, overlapping dialing, and support for up to 256 routing rules per direction.

  • Supports advanced call controls such as number manipulation, white/black listing, trunk grouping, IP trunk priority, ringback tone customization, and dialing rule sets (up to 2000 rules).

Management & Administration

  • Managed via a user-friendly web-based GUI, SNMP (v1/v2/v3), and Dinstar Cloud Management System for remote provisioning and system control.

  • Features configuration backup/restore, firmware upgrades (via TFTP/Web), network capture, syslog, call history logging, NTP synchronization, and advanced debugging tools.

Hardware, Interfaces, & Environmental Specifications

  • Physical interfaces: Supports 4/8/12/16 E1/T1 (RJ48), 2 Gigabit Ethernet (10/100/1000 Mbps), and a serial RS-232 port (115200 bps).

  • Hardware design: Compact 1U form factor; weight approximately 3.8 kg; power input 100–240 VAC, power consumption ~45 W.

  • Environmental tolerances: Operates from 0 to 45 °C, storage from –20 °C to 80 °C, with 10–90% humidity (non-condensing). Compliant with CE and FCC standards.
