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.
4.43 Store Dial Plan
Store Dial Plan - will store the Dial Plan from DRAM / Working Memory to
Flash / Non-Volatile Storage
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
