PhoneTools Features

With the PhoneTools communications program included with your modem, you can:

•Upload and download data files.

•Send faxes at preset times.

•Store incoming voice messages and faxes.

•Retrieve stored messages, faxes, and telephone numbers (telephone number retrieval requires Caller ID service from your telephone company).

•Print a received fax.

For detailed information about operating your modem under PhoneTools, please refer to the PhoneTools online documentation.

Leased-Line Operation

The MultiModem ZBA modem can be used on a two-wire leased line.

A leased line is a private, permanent telephone connection between two points. Unlike normal dialup connections, a leased line is always active. The modems automatically connect when they are attached to the line and are turned on. Because a leased line is always active, one of the two modems on the line must be configured as the originate modem and the other as the answer modem; however, it does not matter which is which.

In the event of an interruption, leased-line modems automatically reconnect when the data line or power is restored.

Setup

1.Open the modem and change jumper J10 to select leased-line operation, and jumper J11 to select either originate or answer operation, depending upon how you intend to use the modem. Refer to Chapter 2, Step 1: Change the Internal Jumpers, for the detailed procedure.

2.Connect a modular telephone cable to the LINE jack. Connect the other end of the cable to a two-wire lease-line jack or terminals supplied by the telephone company.

3.Turn on the modem.

V.92 Operation

This section describes the status of the V.92 features in the initial release. Please note that the V.92 special features require connection to a V.92-capable server.

•General. The V.92 protocol is enabled by default. The AT command that controls this is +MS=.

•Commands. AT commands specific to the V.92 protocol and the new V.44 compression protocol begin with the plus character (+). These commands are in this manual. Also, the S109 register has been modified to support V.92.

•PCM Upstream. PCM Upstream is disabled by default. To upload files at speeds above 33.6 kbps, you must enable PCM Upstream using the command +PIG=1. Please note that this requires connection to a V.92-capable server. Also, please note that since speeds are affected by line conditions, meeting the previous requirements cannot guarantee speeds above 33.6 kbps.

•Quick Connect. Quick Connect, which shortens the handshake time with another V.92 modem, is disabled by default. To enable it, use the command +PQC=0. Quick Connect speeds connect times by skipping the line test during the handshake and using the configuration from the last data connection. Quick Connect works best when line conditions are consistent from call to call. If line conditions are variable, enabling Quick Connect can actually increase the connect time slightly.
