With reference to VoIP, your product allows Class 5 switching via GR.303, which has been one of the ways carriers were migrating to VoIP. Why have they instead gone for over-the-top VoIP option instead of migrating Class 5 voice infrastructure to IP? And what impact has that had on your business?
Occam’s customers have varying business models and service migration strategies. While it is true some have leveraged an ‘over-the-top’ VoIP approach to primary and/or secondary voice service, many of our wireline service provider customers are actively migrating from traditional circuit based class 5 infrastructure to a softswitch model. There is still a noticeable majority of network operators that utilize GR303 but even those operators have an eye towards a pure packet softswitch model in the foreseeable future. But anyway, our BLC 6000 system can support both models from a common service-aware, Ethernet based system.

You also enable another type of Class 5 VoIP migration which is by use of access gateway in the BLC. Carriers like BT have implemented that type of migration option. Are you aware of any others that have followed this migration model?
We have numerous customers employing this approach with initial deployments ranging in size from hundreds to tens of thousands of voice lines served from our line access gateways. We have shipped well over 1 million POTS ports with our BLC systems – each of these capable of native VoIP support. In fact, every one of our POTS interface modules is in fact a native IP line access gateway – a unique differentiating feature of our access solution.
Will carriers at some point bridge their narrowband and broadband infrastructures? What about countries like France where operators do not feel such need (since broadband VoIP lines are quickly replacing pots lines)?
An excellent question. There is evidence that many carriers are doing this now. It’s arguable that one of the world’s largest networks – Verizon – has started this process by deploying FTTP with their FiOS initiative. FTTP by definition is a broadband connection. While the traffic types have not yet converged in that network, the infrastructure is being put in place to support that kind of convergence. To a smaller scale, Occam sees many Tier 2/3 service providers that are embracing a converged infrastructure and a converged traffic approach. Those operators that have migrated to IP based softswitches and are also delivering IPTV are also likely to embrace a pure packet access and aggregation infrastructure. When these two service and infrastructure strategies intersect, you have effectively bridged the narrowband and broadband domains. Occam counts many of its over 300 Tier 2/3 customers in this arena.
