2. Down = 1kΩ link between pads 2 and 3
3. Floating = no link
4. Requires auto-negotiation on port 1 to be disabled (using link MCOL).
5. Requires auto-negotiation on port 2 to be disabled (using link MRXD 0).
6. Requires auto-negotiation on port 3 to be disabled (using link MRXD 1).
7. Requires auto-negotiation on port 4 to be disabled (using link MRXD 2).
Links 22, 31, 40, and MRXD 3 are fixed and should not be changed. Attempting

AT-AR027 VoIP-FXS PIC

The AT-AR027 VoIP-FXS PIC provides two Foreign Exchange Subscriber (FXS)
ports. The ports use RJ-11 connectors and can be connected to standard analog
telephony equipment such as telephones, fax machines and modems. The FXS
interface supplies ring, voltage and dial tone.
The AT-AR027 VoIP-FXS PIC is shown in

AT-AR027 features include:
• Settable ring wave form
• Settable tone generation
• Settable port gain/attenuation for transmit and receive on each port
• 600r, 600c, 900c, Cplx and Cplx2 port impedance.
• Frame buffer management
• Voice activation and silence detection
• Compatible with H.233, Session Initiation Protocol (SIP) and Media
Gateway Control Protocol (MGCP)
When using AT-AR027 PICs with an AR740 router and NSM, a maximum of
four AT-AR027 PICs can be installed in the router and NSM.
More information on protocols and how to configure them on the PIC can be
found in the Software Reference for your switch or router.
