Primary Advantages

• Custom hardware — hardware-optimized bearer path, wire-speed routing and 120 Gb IP backplane to ensure voice quality, system reliability

• Distributed SIP architecture — reduces time to revenue by standardizing interoperability and service delivery

• Rugged telco design — hot swappable modules, full redundancy and alarm interfaces, temperature hardened, NEBS certified

• Cost-effective scalability — 13,824 DS0s in a single 7’ rack with no performance degradation

• Non Blocking with CODECs — G.729ab, G.723.1, G.711 and T.38 Fax.
