  • High‑Speed and Reliable Transmission – Ensures stable and efficient service delivery through advanced Ethernet, optical, and DSL interfaces.
  • Flexible, Modular Design – Scales easily from small to large deployments, ideal for central office or remote outdoor applications.
  • Seamless Network Migration – Provides an easy, cost‑effective transition path from legacy TDM to NGN IP networks.
  • Reduced CAPEX and OPEX – Protects existing equipment investment while minimizing upgrade and maintenance costs.
  • Comprehensive Network Management (NMS) – Offers complete configuration, performance, fault, and security management for optimized access network control.

Core Features

TDM‑Based Capabilities

  • Open PSTN interfaces (V5.2 or 2‑wire analog) supporting standard POTS applications.
  • Support for analog leased lines with or without E&M signaling.
  • Multi‑rate data leased lines with interfaces including V.11, V.28, V.35, OCU‑DP, and G.SHDSL.
  • DS0‑level non‑blocking cross‑connect and grooming for flexible voice and data routing.

TDM over Ethernet

  • Ethernet Interfaces: 10/100/1000Base‑T and 1000Base‑FX SFP.
  • Compliance with RFC 5086 CESoPSN and MEF 8 standards.
  • Up to 8 x E1 over Ethernet per card with ACR synchronization.

Broadband Access

  • Supports ADSL, ADSL2, ADSL2+, and G.SHDSL technologies for broadband delivery.
  • Flexible network interfaces: Fast Ethernet (FE) or Gigabit Ethernet (GE).
  • Integrated Layer 2 switching for advanced data services.
  • Built‑in POTS splitter for simplified MDF cross‑connection.

VoIP Access

  • Fully compatible with H.248, MGCP, and SIP protocols.
  • Bi‑directional voice format conversion between TDM (PCM) and IP codecs (G.711, G.723, G.726, G.729).
  • Advanced voice features: Voice Activity Detection (VAD), Comfort Noise Generation (CNG), and T.38 Fax over IP.

Transmission System

  • Multiple transmission interfaces: E1, G.SHDSL (electrical), STM‑1/4 (optical), or Gigabit Ethernet (optical).
  • Supports diverse network topologies: point‑to‑point, linear, star, ring, and hybrid configurations.
  • Network protection switching enables rapid fault recovery and high service availability.
  • Scalable capacity suitable for small, medium, or large deployments.

Network Management and Maintenance

  • Comprehensive NMS: configuration (CM), performance (PM), fault (FM), security (SM), and inventory management.
  • Integrated line testing tools for quick fault isolation and maintenance.
  • User‑friendly interface designed for intuitive operation and streamlined network supervision.
