Most telecom equipment failures are board failures, and most board replacements are cheaper than the platform documentation implies — provided the board is identified correctly. The difficulty is that manufacturers name boards by function rather than sequence, revisions are not always backward compatible, and the same functional board may exist in half a dozen variants across platform generations. This category indexes control, interface and processing boards across six manufacturers. The subrack or chassis a board fits is the field that matters most, and it is the field least often published.

Equipment condition
New — factory-sealed, supplied through the manufacturer's authorised channel or an authorised distributor, with full manufacturer warranty.
New surplus — unused factory stock, original packaging where available, sourced from decommissioned projects or distributor inventory. Manufacturer warranty may have lapsed; CRS PLUS warranty applies.
Refurbished / tested — previously deployed equipment, cleaned, firmware-checked and functionally tested against the manufacturer's specification before shipment. CRS PLUS warranty applies.
Condition is confirmed in writing on every quotation before you commit to an order.
Warranty
Warranty terms vary by item, by condition and by the supplier the equipment is sourced from. They are stated in writing on the quotation, per line item, before you commit to an order.
Where equipment is supplied new through an authorised channel, the manufacturer's warranty applies and is passed to you.
Send us the part numbers you need and we will confirm warranty terms alongside availability, condition, lead time and price.
