Placing a Toll Saver call

The Toll Saver feature allows you to place a data call using a voice channel, thereby saving the extra cost often associated with placing a data call. By combining the Toll Saver feature with the Netopia ISDN Modem’s built-in data compression, you can transfer up to 128 Kbps of data for the cost of a single voice call.

Note: To place a Toll Saver call, the device you are dialing into must be capable of generating the 3.1 kHz tone necessary for disabling the echo cancellers on the line. Also, check with your Internet Service Provider to verify that this feature (also called “56 permissive calls”) is supported.

To manually dial a Toll Saver call, send the following AT command to the Netopia ISDN Modem:

ATDD <telephone number>

for example: ATDD 14085551234

To configure the ISDN modem to send all outgoing calls as Toll

Saver calls, set S register 61 to 1.

About QuickSelect

The ISDN modem’s QuickSelect feature automatically converts asynchronous Point-to-Point Protocol (PPP) into synchronous (HDLC-based) PPP. This allows for connections to communication servers and routers that have Basic Rate Interface (BRI) ISDN, Primary Rate Interface (PRI) ISDN, or T1 access lines.

Using the Netopia ISDN Modem’s QuickSelect feature, you do not have to manually select the proper protocol for each ISDN call. With QuickSelect enabled, the ISDN modem automatically detects and uses the required protocol. QuickSelect is enabled by default.
