Calix Launches E3 Sealed Ethernet Service Access Nodes

  • Calix
PETALUMA, CA - Broadband access equipment provider Calix introduced an Ethernet Service Access Node (ESAN) family to its Unified Access portfolio – the E3 family of sealed ESANs - along with its first family member, the E3-12C sealed ESAN. The new equipment is intended to bring high-bandwidth services to remote, hard-to-reach locations.

An extension to Calix E-Series platforms, the E3 sealed ESANs provide flexible options for offering high-bandwidth VDSL2 services at the remote node. The environmentally hardened and sealed E3 family combines low-profile, compact form factors with a variety of mounting and powering options to enable extensive deployment flexibility.

Fiber-fed with multiple gigabit Ethernet feeds, E3 ESANs can support bandwidth-intensive services and high broadband services uptake. They allow communications service providers who are pulling fiber deeper into their networks to easily deliver near-fiber speeds to areas still saturated with copper plant.

The E3-12C, the first E3 device to be introduced, is focused on advanced combo VDSL2 copper services deployment in low-density, remote areas. In contrast with the chassis-based C7 Multiservice Access Platform and E7 Ethernet Service Access Platform and the rack-mountable, fixed-form-factor family of E5 ESANs, the E3 is a sealed ESAN VDSL2 delivery vehicle that supports session initiation protocol (SIP) and H.248 voice protocols, remote and -48VDC powering. It can be easily installed virtually anywhere in the access network – on poles, on walls, in low-profile “dog house” enclosures, or even in the basements of MDUs. The E3-12C is fiber-fed, supporting up to two gigabit Ethernet uplinks and preparing the access network edge for bandwidth-intensive services such as video.

Because each unit supports up to 12 combo VDSL2 subscribers, Calix calls the E3-12C a “right-sized” access solution that can be deployed on a pay-as-you-grow basis for capex efficiency.

“We were looking for an access solution that was both the right size for rural deployment and allowed us to deliver advanced VDSL2 services while operationally snapping in to our existing asynchronous digital subscriber line (ADSL) operational model, and we found the E3-12C to be an ideal fit,” says Gary Cantrell, plant superintendent at Adams Telephone Co-Operative in Golden, Illinois. “We weren’t looking for a cheap remote terminal. … We needed a flexible solution that was easy and cost-effective to deploy in remote, rural areas while providing fiber-like speeds over our existing copper. Our goal is to provide advanced broadband services to every member of our community, and with support for VDSL2 with ADSL fallback already integrated, we can leverage the E3 on a pay-as-you-grow basis while strategically pulling ‘Fiber Forward’ into the network.”

Although it is smaller and has a lower combo port count than the other E-Series ESANs, the E3-12C supports the same key Ethernet protocols, features and management functionality, such as a robust Ethernet switching fabric for layer 2 switching with layer 3 services. In addition to supporting VDSL2 with ADSL2+ fallback, the E3-12C also supports bonding across VDSL2 and ADSL for future bandwidth flexibility. Two small-form-factor-pluggable (SFP) GE uplinks provide connectivity upstream or in a ring configuration, although the units can be linked via either copper or fiber in a daisy-chained configuration.

Other E3-12C features supported include:

- Dual GE uplink with 802.1w rapid spanning tree protocol (RSTP) and 802.3ad link aggregation

- RSTP ring support

- Layer 2 switching and forwarding for deployment simplicity and Layer 3 awareness for scalability and security

- Integrated Internet group management protocol (IGMP) v2 and v3 snooping for IPTV

- Lifeline voice with native SIP or H.248 conversion

- Dynamic host configuration protocol (DHCP) relay and snooping for facilitated network security

- Service prioritization via IEEE 802.1Q virtual local access networks (VLANs) and 802.1p support

- Support for multiple service delivery models, including VLAN per service, VLAN per port, or hybrid

- Full Calix Management System (CMS) integration for complete network visibility and management
