and a remote phone rings without digits being dialed. This is a useful tool for customer requirements such as:

•The provision of an Off-Premises eXtension (OPX) from a private branch exchange (PBX). Connection PLAR allows remote users on Foreign Exchange Station (FXS) ports to look to a central PBX like physical extensions.

•The provision of dial-tone from a remote PBX. Many customers want to offer toll-bypass VoIP services without having the routers provide dial- tone or change their existing dialplan. This allows stations at remote sites to look like they are physically connected stations to a PBX.

Dial in PLAR Considerations and Limitations

•Dial in PLAR is a switched VoIP call. The call is setup on an as-needed basis. With connection PLAR, no bandwidth is consumed while the phone is on hook. When a phone connected to a POTS dial peer is taken off-hook, the call is automatically connected and the remote phone begins to ring.

•Dial in PLAR can work between any type or combination of Foreign Exchange Office (FXO), and/or FXS) telephony port / device.

•Dial in PLAR does not collect digits from the connected Telephony device. Once a dial plan has been entered into the ATPM, PLAR can be enabled without need to alter the dial plan. Note: All other Dial plans set for this starting port will become ineffective.

Always be sure to Store, the Dial Plan from working memory / DRAM to Flash Memory / Non-Volatile Storage. Storing to Non-Volatile Storage ensures that you have saved the dial plan which can then be restored on request.

Note: The Dial Plan in the Non-Volatile Storage is not the working Dial Plan. If the Gateway is turned off for what ever reason, the Dial Plan from Non- Volatile Storage is copied into the Flash / Working memory and processes phone calls accordingly
