• 47 CFR 52.35(e)(2) defines intermodal ports to include wireline-to-wireless, wireless-to-wireline and ports involving interconnected VoIP service. in context
• Under 47 CFR 52.35(d), non-simple wireline-to-wireline and intermodal port requests must be completed within four business days, unless the new provider or the customer asks for a longer period. in context
• Under 47 CFR 52.35(a), US carriers must complete simple wireline-to-wireline and intermodal ports within one business day, unless the new provider or the customer asks for a longer period. in context
• The several-week porting lead time in AWS guidance does not conflict with the FCC one- and four-business-day intervals. The FCC intervals govern completion after a valid request, apply only to US local wireline and intermodal ports, and allow longer periods at the customer's request, while project lead time also covers preparing the request and scheduling the cutover. inferred in context
• Multi-line enterprise ports into UCaaS calling plans usually fail the single-line test of the FCC simple port definition, so the four-business-day non-simple interval, not the one-day interval, is the relevant US regulatory bound. inferred in context
• For simple ports under 47 CFR 52.35(a), Monday through Friday are mandatory business days and 8 a.m. to 5 p.m. are minimum business hours, excluding the current provider's company-defined holidays. in context
• For 47 CFR 52.35, intermodal ports include wireline-to-wireless, wireless-to-wireline, and ports involving interconnected VoIP service. in context
• The one-business-day simple port interval in 47 CFR 52.35(a) applies unless the new provider or the customer requests a longer period. in context
• A simple port LSR received after the 1 p.m. cutoff is treated as received at 8 a.m. local time on the next business day. in context
• To be eligible for activation at midnight the same day, the current provider must receive an accurate and complete simple port LSR between 8 a.m. and 1 p.m. local time. in context
• Under 47 CFR 52.35(d), a non-simple wireline-to-wireline or non-simple intermodal port must be completed within four business days unless the new provider or customer requests a longer period. in context
• Under 47 CFR 52.35(a), US carriers required to port numbers must complete a simple wireline-to-wireline or simple intermodal port request within one business day. in context
• Small providers, as described in the 2009 LNP Porting Interval Order, had to comply with 47 CFR 52.35 by February 2, 2011. in context
• Carriers holding a Commission waiver must complete a simple wireline-to-wireline or simple intermodal port within four business days unless a longer period is requested. in context
• US rules require providers to complete a simple wireline-to-wireline or simple intermodal port within one business day, unless the new provider or the customer asks for a longer period. in context
• Cisco's advertised 10 to 35 business day port processing, and its five-business-day minimum lead time, do not conflict with the FCC's one-business-day simple-port interval. The FCC interval applies to the carrier-to-carrier step after a valid request, while Cisco's figures cover the whole order, including validation, rejections and FOC scheduling. inferred in context
• US rules set a four-business-day interval for non-simple wireline-to-wireline and non-simple intermodal port requests. in context
• In the US, carriers required by the FCC to port numbers must complete a simple wireline-to-wireline or simple intermodal port request within one business day. in context
