    * Denotes default setting. Setting the DTE to DCE Rate The Omni 288S DTE to DCE rate can be determined in three ways: 1. By default the DTE to DCE rate is equal to the DTE speed set by S20 (default S20=1 for 115200 bps).
  • Page 40: Data Compression

    Data Compression The Omni 288S supports both V.42bis and MNP5 data compression protocols. Data compression works by representing the original data information in less bits and transmitting the reduced data bits through the data link. The receiver recovers the original information by reversing the representing process.
  • Page 41: Hardware Or Software Flow Control

    Chapter 4 - Advanced Data Communications The compression efficiency of V.42bis is generally higher than that of MNP5. In some cases it can be 50% to 100% higher and in other cases it is just slightly higher. In general, it is about 50% more efficient. Run Length Encoding Run-length encoding is applied in an attempt to avoid sending long sequences of repeated characters (data).
  • Page 42 DTE. Turn ON the RTS and the modem will start sending data again to the DTE. In asynchronous full-duplex applications, the Omni 288S always responds to the RTS signal as a flow control signal. The Omni 288S defaults automatically to this hardware flow control setting and it is a better choice.
  • Page 43: Chapter 5 - Synchronous Mode Operation

    Chapter 5 - Synchronous Mode Operation Chapter 5 - Synchronous Mode Operation This chapter introduces you to the use of the Omni 288S for synchronous operation. The modem can be used as a synchronous modem when it is connected to a synchronous computer or terminal. It is of course necessary to make sure that the remote modem and system are also set to synchronous.
  • Page 44: Clock Options

    Chapter 5 - Synchronous Mode Operation Clock Options Synchronous data must be transmitted and received with a common timing clock. This timing clock is used to transmit data from the DTE to the modem which modulates the data according to this clock. The receiving modem recovers the clock and data from the carrier and sends the data to the receiving DTE along with the clock.
  • Page 45: Dialing From Synchronous Mode

    Chapter 5 - Synchronous Mode Operation You can always use the panel operation to control and configure the modem and use the manual dial and answer to operate the modem. Dialing from Synchronous Mode 1. Dial from the terminal using asynchronous commands. Set &M1 and use asynchronous AT commands to dial the number.
  • Page 46: Chapter 6 - Leased Line Operation

    The Omni 288S supports only 2-wire leased lines. Connecting to a 2-Wire Leased Line The Omni 288S is equipped with a phone jack for dial-up line connections. Connections can also be made to a 2-wire leased line using the same jack.

This profile is modified locally and the line can be disconnected during this time.
  • Page 56 Local profile modification is done by loading this profile as the active settings and then modifying and saving the active settings back to the profile. Then the connection is reestablished and the profile transmitted to the remote modem. Reading a remote profile b into a local profile a is acheived by the command: AT*Rab Local user profile number a=0-3...
  • Page 57: Caller Number Delivery (Caller Id)

    With CND service, the phone company’s central office will send the coded caller information to the called station. This information is sent once between the first and second. The Omni 288S modem can decode this caller information and present it to the connected computer/terminal during the second ring period as part of the call progress ring message.

    “ON” part (cadence) of the ring. The Omni 288S modem can distinguish up to four types of ring signals and can be commanded to answer or not answer any one of these four types of ring signals.
  • Page 60: Extended Distinctive Ring (Edr)

    DTMF tones, once detected by the modem, will be reported as RING or RING n to the software application. With these two functions, the Omni 288S can be installed with an answering machine or voice telephone set at home. In most cases, the modem should not be set to answer regular rings, nor to report them.
  • Page 61: Setting Up Edr

    Setting Up EDR The new EDR can be used at home where multiple phones are installed in parallel. Once this function is enabled, the modem will go into EDR mode after the ring disappears, and it will be able to detect the data/fax CNG tone and DTMF tones, and report them as different types of rings.
  • Page 62: Edr Application Example

    The timing relationship between the Caller ID (if enabled), EDR, and ring detection is as follows: ring1 ring2 ***--------***--------***------------------------------ 3sec +------+---+------+---+------+---+-------------+---- CID/EDR RD CID =Caller ID task Note: During the EDR period, any AT command will disable the EDR function.

    The Voice Command State provides several DTE options. The modem may wait for an unspecified time after playing a welcome message, or switch to other modes as part of a DTE call discrimination algorithm. Voice Data States The DCE is in Voice Data State when the DCE is operating in voice mode and is communicating with a remote station or with one or more local devices which are capable of translating analog signals to voice (e.g., speaker) or voice to analog (e.g., microphone).
