Frequently asked questions
How much does the Cisco 1-Port 4-Wire 56-/64-kbps CSU/DSU WAN Interface Card - For Wide Area Network - 1 x RJ-48S Synchronous Serial WAN (HWIC-1DSU-56K4=) cost?
Pricing for the HWIC-1DSU-56K4= is available on request. Send a quick quote request and a Uniqcli specialist will confirm the current price, stock, and lead time, usually within one business day. Lower pricing is available for volume, GPC, and emergency-acquisition orders.
Is the HWIC-1DSU-56K4= TAA compliant and available for government and DoD buyers?
Often yes, but it depends on the unit. Cisco manufactures the HWIC-1DSU-56K4= in several countries, so Trade Agreements Act (TAA) status varies by production lot. Uniqcli is an authorized Cisco partner: we confirm the country of origin before shipment, and if a given HWIC-1DSU-56K4= is not TAA-designated, we will source a TAA-certified equivalent of the same model. Either way the result is DoDIN APL-ready procurement for US federal, DoD, state, local, education, healthcare, and enterprise buyers, with Government Purchase Card (GPC) acceptance and FAR-based urgent and emergency acquisition support. Request a TAA-compliant quote for the HWIC-1DSU-56K4= and a specialist will confirm compliance, price, and lead time, usually within one business day.
Can I buy the HWIC-1DSU-56K4= as a single unit or in volume?
Both. Order a single HWIC-1DSU-56K4= through the cart, or ask about lower pricing for volume orders, Government Purchase Card (GPC) purchases, and emergency or urgent (FAR-based) acquisitions. There is no payment up front: we confirm availability and the final total before invoicing.
Where can I find the HWIC-1DSU-56K4= datasheet and specifications?
The specifications section on this page lists the published specs for the HWIC-1DSU-56K4=, including ports, power, and dimensions where Cisco publishes them. Ask us for the full Cisco datasheet and we will send the current PDF with your quote.
Need the HWIC-1DSU-56K4= TAA-compliant for federal or DoD?
Cisco builds this model in multiple countries, so TAA status depends on the production lot. We confirm country of origin before shipment, and if a unit isn't TAA-designated, we'll quote a TAA-certified equivalent of the same model, DoDIN APL-ready and GPC-payable.
