Frequently asked questions
How much does the Cisco Single-Wide High Density Analog Voice Service Module with 24 FXS and 4 FXO - For Voice - 24 x RJ-21 FXS, 4 x RJ-11 FXO - Twisted Pair (SM-X-24FXS/4FXO-RF) cost?
Pricing for the SM-X-24FXS/4FXO-RF 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 SM-X-24FXS/4FXO-RF TAA compliant and available for government and DoD buyers?
Often yes — it depends on the unit. Cisco manufactures the SM-X-24FXS/4FXO-RF 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 SM-X-24FXS/4FXO-RF 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 SM-X-24FXS/4FXO-RF and a specialist will confirm compliance, price, and lead time — usually within one business day.
Can I buy the SM-X-24FXS/4FXO-RF as a single unit or in volume?
Both. Order a single SM-X-24FXS/4FXO-RF 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 SM-X-24FXS/4FXO-RF datasheet and specifications?
The official Cisco datasheet is available on this page (open the gated datasheet for the full PDF), and the Tech Specs section lists ports, power draw, dimensions, and licensing for the SM-X-24FXS/4FXO-RF.
Need the SM-X-24FXS/4FXO-RF 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.
