The Cisco BRI-4B-S/T is a 4-port ISDN Basic Rate Interface (BRI) S/T WAN interface card, primarily used in modular Cisco routers to provide ISDN connectivity. It's part of Cisco’s modular WAN interface lineup designed for enterprise and branch network environments that require legacy ISDN access.

Features:

• 4 ISDN BRI S/T Ports: Offers four Basic Rate Interface (BRI) ports using the S/T interface standard (non-U interface, meaning an external NT1 device is required)
• Integrated NT1 Not Included: Requires an external NT1 for network termination, as it does not have NT1 functionality.
• Supports Voice and Data Services: Enables simultaneous voice and data transmission over ISDN lines—commonly used for backup WAN connectivity or in regions where ISDN is still in use.
• Form Factor: High-Speed WAN Interface Card (HWIC)
