❓ FAQ — Frequently Asked Questions
Q1 — Which ISAM platforms is this card compatible with?
The NALS-A (3FE61233BA) card is specifically designed for Nokia/Alcatel-Lucent 7302 ISAM FD and 7330 ISAM FD chassis. These multiservice access platforms support up to 16 to 18 line cards per chassis, allowing up to 1,296 subscriber ports in a single cabinet. It is recommended to check the node’s software version (release) before installation to ensure full compatibility with Layer 3 MultiDSL features.
Q2 — Which DSL protocols does this card support?
Thanks to its MultiDSL architecture, this card supports multiple xDSL technologies on the same copper infrastructure: ADSL2+ (up to ~24 Mbit/s), VDSL2 (up to ~200 Mbit/s over short distances), and SHDSL for symmetrical business connections. It also manages POTS telephony on the same copper pair thanks to the built-in EA splitter, without interference between voice and data services.
Q3 — What is the purpose of the built-in EA splitter?
The integrated EA (External Access) splitter on the 48 lines physically separates voice frequencies (POTS, 0–4 kHz band) from DSL data frequencies (high frequency) on the same copper pair. This avoids installing external splitters in the racks, simplifies central wiring, and reduces infrastructure costs. The coexistence of analog voice + high-speed DSL is thus ensured transparently for the subscriber.
Q4 — Does opening the packaging affect the warranty?
No, opening the packaging does not affect the warranty in any way. The product is new, never deployed, and the packaging was opened only for a visual quality check before shipping. Our 30-day professional satisfaction or refund warranty fully applies upon receipt of the package.
Q5 — Is this card suitable to replace a defective card in production?
Yes, this is precisely the main use of this type of spare part in spare management. The 3FE61233BA can replace a defective NALS-A card in an existing ISAM FD 7302 or 7330 node, allowing restoration of MultiDSL and POTS services on the 48 affected lines without chassis replacement. The hot-swap insertion procedure depends on the firmware version of the controller — please consult your Nokia ISAM documentation.
Q6 — What are the delivery times and conditions?
Shipping is carried out within 24 business hours after payment confirmation. You will receive a carrier tracking number as soon as the package is handed over. Delivery is estimated at 2 to 4 business days depending on the destination. All professional telecom equipment of this type is packaged with anti-static and shockproof materials to ensure its integrity until delivery.
