Calix has expanded its access network portfolio with the introduction of its E-Series IP service edge node, a new platform designed to support a smooth transition to FTTP builds.
The Calix E-series offers up to 16 Gigabit Ethernet uplinks, multiple voice termination options, multiple powering options, compact enclosures, battery backup, integrated cross-connect panels, and advanced cable management features.
The Calix E5 supports multiple voice termination scenarios. In a "DSL overlay" architecture, common to early FTTN initiatives, integrated POTS splitters separate voice traffic for delivery back to the central office (CO) or remote terminal over existing copper pairs. Gigabit Ethernet uplinks transport data and IPTV to either a Calix C7 or any commercial Ethernet switch or router in the CO.
Alternatively, the Calix E5 can terminate POTS at the service area interface (SAI). In this "DSL+POTS combo" model, service providers can simplify physical connectivity at the cross-connect and optionally retire the upstream "feeder" portion of the copper plant. In this configuration, the Calix E5 converts POTS to VOIP using SIP or H.248 signaling for transport over Gigabit Ethernet along with data and IPTV services. At the CO, the voice services can be converted back into a GR-303 TDM voice format or handed off to the network as VOIP.
Existing Calix C7 outside-plant cabinets range in size from 240 to 2,880 physical copper or fiber network terminations. The new Calix E5 outside plant cabinet is optimized for deployment adjacent to SAI cross-connects, and provides cost-optimized support for 24 to 384 DSL or POTS+DSL combo subscribers.
Key features include:
- 1. Up to 16 SFP-pluggable Gigabit Ethernet uplinks for a smooth evolution to future unicast-intensive IPTV service models;
- 2. VDSL2 with integrated overlay POTS splitters for 24 to 192 subscribers;
- 3. VDSL2+POTS combo cards that can packetize voice for 24 to 384 subscribers, working with upstream Class 5 TDM switches or VOIP softswitches;
- 4. VDSL2 technology that automatically falls back to ADSL2+ and ADSL, allowing one line card to service both IPTV and existing high-speed data (HSD) subscribers;
- 5. Flexible options for local or managed remote powering;
- 6. Optional integrated cross-connects for up to 1,200 copper pairs;
- 7. Optional mounting kits supporting pad or pole-mount configurations; and,
- 8. Compact 2' by 2' by 4' footprint in a GR-487 compliant outdoor cabinet for deployment within existing service provider right-of-ways.
