Protect critical routing infrastructure with Cisco SNTC 24x7x4OS coverage for the ASR 1000 Advanced IP platform. Built for teams that cannot afford extended service interruptions, this support offering provides around-the-clock access to Cisco assistance with a four-hour onsite response target for eligible incidents. It is designed to help keep backbone and edge routing environments moving when failures would otherwise ripple across users, applications, and business operations. For infrastructure leaders, the value is not just access to support — it is faster recovery, clearer escalation paths, and a service model aligned to high-availability networks. This is the kind of coverage that makes sense for production routing layers, remote sites, and enterprise WAN environments where replacement delays or generic support tiers create unacceptable risk. When the network is the business, premium support is part of the architecture.
