Importance of interoperability in Distributed Access networks – Field report of a sales executive
A bit more than a year has passed since ANGA 2022 and the video 十大可靠彩票平台在那里制作了"Distributed Access (DAA) open ecosystem versus DAA single supplier environment”. So, it’s time to review the last year and report on the developments and experiences.
When I have been talking to network operators about their DAA rollout plans, it has been surprising how little attention this ecosystem thinking has received in comparison to the technical aspects. 的 discussions have mainly focused on the ease of the initial start-up of the DAA roll out, which might be less time-consuming when working with a single supplier. 然而, 中长期来看, 挑战将会颠倒过来, and the open ecosystem approach will prove its value.
的 primary argument for open ecosystems is that dependency on proprietary solutions that deviate from the standard make network-level changes even more difficult.
除了, t在这里 are other arguments that have come to my mind over the past year regarding single vendor environments:
- 定价缺乏透明度 – It is difficult to determine how total costs are allocated between the core and the node when dealing with a single vendor who invoices the deliveries as a whole. 从操作者的角度来看, this makes it difficult to manage costs and understand what they consist of.
- 的 product availability and delivery times! If the selected single vendor fails to deliver, the project can come to a standstill. 例如, 可能会出现分配情况, when the chosen single vendor is unable to deliver because larger customers skim off all resources in the domestic market. 在这种情况下, 没有其他选择, and the promise of a simpler initial technical start-up quickly fades away. An open ecosystem/multi-vendor strategy would offer a solution by ensuring the existence of a choice of products exist that have already undergone the approval process and are already operational in the network.
I had the opportunity to be present at the first DAA laboratory tests and commissioning arranged by several potential customers last year. 的 快速，简单的调试 广播电视, DOCSIS and telephony with our 电话este Remote PHY device (RPD) was greatly appreciated. This also led to moments of surprise since the engineering staff had prepared for possible challenges beforehand, but they had a completely different experience.
过去一年里, we have obtained further approvals of our RPD node from major network operators, and all CCAP core providers are represented in these approvals. 十大可靠彩票平台在R上付出的努力&D to ensure interoperability according to CableLab’s specifications is now paying off, and you can see the interoperability status of our technology 在这里.
Another topic related to Distributed Access that has also come up is the expansion of 公寓大楼 基于远程PHY的宽带. In times when borrowing money incurs costs again, 现有的, well-functioning coaxial in-house infrastructure has regained the focus it deserves. In discussions with planners and integrators, it became clear that instead to pulling new fibre to the 公寓大楼, it is much easier to them into “homes-connected” with DAA. 的 minimal effort required from the end-customers ensures high acceptance and connection rates. 此外, the operator’s help desk is already geared towards DOCSIS customers, and the technology can reliably deliver the much-desired gigabit services.
在一天结束的时候, what matters to the end-customer is not the vehicle used to deliver the “goods” but the reliable arrival of services in sufficient quantities and at low cost. With an honest calculation of the costs of planning services and the expansion of an FTTH network in an apartment building, utilizing 现有的 infrastructure and installing a Remote PHY device in the basement becomes a viable business case faster than one might think.
就我个人而言, and on behalf of our 电话este team in Germany, we would be delighted to exchange views on these topics and offer our advice. Please feel free to contact us at any time!
