Unlock flexible voice connectivity within Cisco’s 4000 Series Integrated Services Routers (ISRs) with this high-density Network Interface Module (NIM). The module combines 2 ports of FXS/FXS-E/DID and 4 FXO ports into a single, compact card that slots into Cisco 4000 Series ISRs with available NIM bays. Built for modern hybrid voice deployments, it lets you connect analog phones or Direct Inward Dialing (DID) capable devices while preserving your IP telephony architecture for SIP trunks, unified communications, and branch-office resilience. Designed for scalability, reliability, and seamless integration with Cisco’s voice ecosystem, this NIM is a cornerstone for a cost-efficient, future-ready voice gateway.

  • Flexible telephony in one module: 2 ports that can be configured as FXS, FXS-E, or DID alongside 4 FXO ports provide versatile analog and voice gateway capabilities for small offices to distributed sites.
  • High-density, scalable expansion for Cisco 4000 Series: Integrates into the ISR’s NIM slots to maximize port density without expanding the chassis footprint, enabling progressive growth of voice services as your network evolves.
  • DID support and hybrid voice integration: The FXS ports support Direct Inward Dialing configurations, enabling direct dialing into your private networks, while FXO ports connect to PSTN trunks or legacy circuits for reliable mixed-mode operation.
  • Designed for reliability and ease of management: Part of the Cisco 4000 family, this NIM is designed for long-term operation with straightforward IOS XE-based management and consistent configuration across Cisco voice platforms.
  • Seamless interoperability with Cisco voice ecosystems: Optimized to work with Cisco Unified Communications Manager (CUCM), Cisco Unified Border Element (CUBE), and other Cisco voice services, providing a cohesive, end-to-end solution for enterprise voice.

I really like these sheets. They are soft, lightweight, and fit my twin mattress perfectly. The lavender color looks beautiful in person and they feel comfortable to sleep on. After washing, they still looked nice and didn’t wrinkle much. Great quality for the price!

Bed Sheets
Color: Bright White Striped, Size: Queen
I’m really happy with these bed sheets. They feel soft and comfortable against the skin, and the crisp white color gives the bed a clean, fresh look. The fabric is lightweight but still feels durable and well made. They fit the mattress nicely and stay in place throughout the night. After washing, they came out looking great with no noticeable shrinking or loss of softness.

Perfect Lightweight Sheets for Sensitive Hot sleepers
Color: Cream, Size: Queen
These sheets are soft, thin, and absolutely perfect for me. I have advanced CRPS and erythromelalgia, so I deal with severe nerve burning and heat sensitivity and cannot tolerate being overheated at all. I keep our AC between 56–64 degrees constantly, and since our studio is small, it usually stays around 61–63. These sheets have been a lifesaver for sleep. They are lightweight, breathable, and don’t trap heat, which helps me avoid extreme flare-ups and the intense burning pain I deal with. I'm bedridden so I need to be comfortable. They feel comfortable against my skin and don’t worsen my symptoms when I’m already in a lot of pain and look nice, wash nicely. For the price, they are also a great value. I’m genuinely grateful to have found something that helps me rest more comfortably. Will be buying more for us and gifts.
