Nortel NT5S20BAE6 (telecommunications transmission and networking portfolio) Telecom System Card / Module

The Nortel NT5S20BAE6 is a Business Secure Router (BSR) ADSL router with four Ethernet LAN ports and a single ADSL WAN port, part of Nortel’s BSR family of small-office security appliances combining routing, firewall and VPN functions with a built-in DSL modem. The BSR range let a small branch or home office connect directly to a DSL circuit without a separate modem, while still providing the same secure-router feature set as Nortel’s other BSR/VPN Router products for site-to-site or remote-access connectivity back to a head office. Genuine BSR ADSL routers of this generation remain a routine requirement for maintaining or expanding small-branch connectivity on an existing deployment. Confirm the exact ADSL variant (ADSL1/ADSL2+) and firmware release required for your DSL circuit before ordering. Tech-Star (UK-based, shipped worldwide) stocks Nortel BSR hardware to support ongoing network maintenance projects.
