VIC-4FXS/DID - Cisco UCS Virtual Interface Card Overview
VIC-4FXS/DID - Cisco UCS Virtual Interface Card is a genuine modular capacity expansion product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco family, the VIC-4FXS/DID unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is deployed as a standalone unit or as part of a larger managed network, following the standard operating procedures of the platform.
From a specification standpoint, it offers 4 ports for client, server or uplink connectivity. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Cisco hardware already running in the environment.
Typical deployments include adding ports and performance to existing chassis systems, modernizing legacy platforms with compatible line cards, and mixing copper, fiber and high-speed uplinks in one chassis. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “4 port FXS or DID VIC”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
Every unit at LinkNewNet is inspected and tested before dispatch, and stock is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Our warranty coverage and responsive technical support protect the purchase after it arrives, and our team can confirm revision levels and software compatibility before you order. For volume requirements we also offer configuration checks and staged delivery options.

| Product Type: | Voice Interface Card (VIC) |
Marketing Information | |
The 4-port high-density FXS/DID VIC can support up to 4 foreign-exchange-station (FXS) ports for directly connecting phones or fax machines, or it can be used to connect up to four direct-inward-dial (DID) analog trunks, providing customers the flexibility they need for their unique business environment. Each port on the 4-Port FXS/DID VIC is selectable for use in either FXS or DID mode. The 4-Port FXS/DID VIC is the same size as the existing two-port voice interface cards (VICs), allowing it to slide into either WIC/VIC slot or VIC slot in Cisco 1751 and 1760. The VIC-4FXS/DID in the Cisco 1700 is used to connect analog phones or fax machines. The long-distance calls between small enterprise branch offices and headquarters are carried by IP network, while the local calls are carried by PSTN, which also provide backup to the IP network. | |

VIC-4FXS/DID - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco module/line card expands the capability of a chassis platform, adding interface density, forwarding capacity, or service features. It is installed in a matching chassis slot and managed as part of the parent platform.
Deployment guidance: When planning this VIC-4FXS/DID unit into a network, confirm the software image (IOS/IOS-XE/NX-OS) required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Cisco reconditioning process: Every pre-owned Cisco unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Cisco management tools.
Related models in this family: VIC3-2E/M, VIC2-2E/M, VIC2-2FXS, VIC2-2BRI-NT/TE, VIC2-2FXO. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
