Technical Specifications

Overview & Key Capabilities

The MTG1000 (Low-Density E1/T1 Digital VoIP Gateway) is a compact, cost-effective trunk gateway designed for efficient interconnection between traditional PSTN and VoIP/IP networks. It comes in a 1U chassis and offers configurations with 1 or 2 E1/T1 ports, supporting high call-throughput and flexible routing.

With a robust DSP design, it ensures high-performance PCM-to-IP conversion, even under full load conditions.

Protocol Support & Routing Flexibility

  • PSTN Protocols: Supports ISDN PRI, ISDN SS7 with link redundancy, and R2 MFC.

  • Fax and Modem: Supports T.38 fax, pass-through fax, and modem/POS communication.

  • Call Routing Options: Offers versatile routing paths: PSTN-PSTN, PSTN-IP, and IP-PSTN.

Voice Codecs & Quality Enhancements

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

  • Voice Quality Features: Includes silence suppression, comfort noise generation (CNG), voice activity detection (VAD), jitter buffering, and echo cancellation (G.168) with up to 128 ms tail length.

SIP & Network Features

  • SIP Protocols: Supports SIP v2.0, SIP-T, and multiple related RFCs (e.g., RFC3372, RFC3204, RFC3398).

  • SIP Capacity: Up to 256 SIP accounts, as well as multiple SIP trunks.

  • NAT Traversal: Features Dynamic NAT and Rport for seamless SIP connectivity.

  • Routing Rules: Includes intelligent routing based on time schedules, caller/called number prefixes, priority trunking, overlapping dialing, and up to 256 rules per direction.

Management & Monitoring

  • Administration Tools: Equipped with a web-based GUI, SNMP v1/v2/v3 support, automated provisioning, and centralized cloud-based management.

  • Diagnostics & Logging: Supports data backup/restore, firmware upgrades via TFTP/Web, network capture, syslog (debug/info/warning/error), call history logging, and NTP synchronization.

Call Capacity & Hardware Design

  • Handles up to 60 simultaneous calls, similar to the MTG1000.
