Power Level The modem's leased-line mode transmission power level can be adjusted from 0 dBm to -27 dBm in 1 dBm increments. If a dial-up model is used for 2-wire leasedline connection, the transmission power is limited to -9dBm for the Omni 288P and to -3dBm for the Omni 288S. LLINE TX POWER AT*P0 ... AT*P15 The default is -9 dBm. The adjustable range is from 0 to -15 dBm, effective in leased-line operation only. If bit 3 of S35 is set, this range will change to -12 to -27 dBm. Handshake Mode In a typical dial-up connection, the originating modem dials the number and waits for the answering modem's carrier signal. The answering modem can answer the call after a specified number of rings, or be commanded to answer immediately. In a leased-line connection, the communication circuit between two modems is always present. Dialing and waiting for rings does not occur in this situation. If these two modems want to establish a data link, one must be designated as the originator and the other as the answerer. You can set this manually or automatically. Manual Connection Set the modem to leased-line mode. Type the asynchronous command ATD to the originating modem and ATA to the answering modem, or press O on the IDLE SCREEN menu of the originating modem and press A on the IDLE SCREEN of the answering modem. On an LED model, press the VOICE/DATA switch to make the modem go off-hook and on-line and use the ORG/ANS switch to select originate or answer mode. For the Omni models, use AT*Mn or set S14b0 to select originate or answer mode. 12-2
