What is the maximum number of PSTN office lines this module supports?

The NIM-4FXO provides 4 FXO ports, allowing connection to up to four PSTN office lines, making it ideal for mid-sized offices transitioning to IP telephony.

How does a 4-port FXO module improve on smaller analog voice cards?

Four ports enable multi-line PSTN connectivity in one module, reducing the need for multiple cards and simplifying administration for offices with several telephone lines.

What is the role of the dedicated DSP in processing PSTN calls?

The dedicated DSP handles analog-to-digital conversion and codec processing for voice quality, ensuring clear calls whether bridging PSTN lines to IP phones or recording conversations.

Can the NIM-4FXO support both inbound and outbound PSTN calls?

Yes, FXO ports handle both incoming and outgoing calls, providing full-duplex PSTN line access for diverse calling patterns.

Is the NIM-4FXO suitable for offices requiring PSTN backup links?

Yes, offices can dedicate some PSTN lines to backup connectivity, ensuring voice and critical data can continue if primary WAN links fail.

Does this module support online installation without service loss?

Yes, the NIM-4FXO supports OIR hot-swap capability, though calls using those ports will briefly disconnect during module replacement.

What are typical lead times for the NIM-4FXO to arrive in the GCC?

Lead times depend on stock levels and ISR router configuration. Contact Procure.ae to confirm availability and delivery schedules.

Does Procure.ae offer installation support for multi-line FXO modules?
