The Cisco 2- and 4-Port ISDN BRI S\/T Network Interface Modules (NIMs offer investment protection by providing data connectivity to legacy ISDN networks for the 4000 Series ISRs. \u003cspan\u003eISDN BRI NIMs enable branches to use legacy ISDN Basic Rate Interface (BRI networks for data connections. Because they support industry-standard ISDN dialup capabilities, these modules can be deployed as the main WAN connection over ISDN BRI, dial backup over ISDN BRI, or a combination of the two. Each physical interface supports data traffic over two 64-kbps B channels, which can be automatically bundled together using Multi-Link Point-to-Point Protocol (MLPPP. The Cisco 2-port ISDN\u003cspan\u003e BRI NIMs offer many of the same features as the ISR G2 Series ISDN BRI modules and can thus be smoothly deployed without any additional training\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eCisco 4221 2 port Gigabit Ethernet Router Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaximum number of NIMs: 2\u003c\/li\u003e\n\u003cli\u003eMinimum Cisco IOS Software release: 16.6.1\u003c\/li\u003e\n\u003cli\u003eCisco IOS XE feature set: IP Base and up\u003c\/li\u003e\n\u003cli\u003eOperating temperature: \u003cspan\u003e32° to 104°F (0° to 40°C\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eStorage temperature: \u003cspan\u003e-4° to 149°F (-20° to 65°C\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eRelative humidity: \u003cspan\u003e10% to 90%, noncondensing\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cisco","offers":[{"title":"Default Title","offer_id":47592396095705,"sku":"02-127738","price":4240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0016\/5327\/6707\/files\/untitled_design_-_2020-03-10t143425.852.png?v=1765430559","url":"https:\/\/www.aloinfousa.com\/zh\/products\/cisco-4221-2port-gigabit-ethernet-router-isr4221-k9-discontinued","provider":"aloinfousa.com","version":"1.0","type":"link"}
