Cisco ATA 192 analog telephone adapter

The Cisco ATA 192 connects two analog telephones or fax machines to an IP network using SIP registrations. It includes a built-in router so the device can sit at the network edge without extra hardware. Small offices and cloud UC subscribers use it to keep existing analog endpoints while moving voice traffic to VoIP.

Two RJ-45 and two FXS ports for simple integration

Dual 10/100Base-T ports link the adapter to the LAN and pass connectivity to a downstream device such as a PC. Two FXS (RJ-11) ports each support an independent SIP line for phones, fax units or paging systems. Wall-mount brackets let the unit fit in wiring closets or on desk surfaces where AC power outlets are scarce.

Steady 100 Mbps throughput under continuous voice

Fast Ethernet interfaces maintain 100 Mbps during sustained call traffic and fax sessions without the burst-only peaks seen on slower links. The integrated router handles NAT and QoS for the attached analog devices so voice quality remains consistent across long conferences or high-volume fax transmissions.

Questions about this item

What is the maximum sustained throughput of the Fast Ethernet ports?

The two 10/100Base-T ports are limited to 100 Mb/s under continuous load.

How much heat or noise does the unit produce when running all day?

The adapter has no fan and draws minimal power, so it runs silently and stays cool during continuous use.

Which analog devices can I plug directly into the FXS ports?

You can connect standard analog phones or fax machines to the two RJ-11 FXS ports.
