Information is transferred between the CX20493 LSD and the CX84100 V.22bis Modem
through the DIB_P and DIB_N pins. These pins connect to the CX84100 V.22bis Modem
DIB_DATAP and DIB_DATAN pins, respectively, through the DIB.
The TLI integrates DAA and direct telephone line interface functions and connects
directly to the line TIP and RING pins, as well as to external line protection components.
Direct LSD connection to TIP and RING allows real-time measurement of telephone line
parameters, such as the telephone central office (CO) battery voltage, individual
telephone line (copper wire) resistance, and allows dynamic regulation of the off-hook
TIP and RING voltage and total current drawn from the central office (CO). This allows
the modem to maintain compliance with U.S. and worldwide regulations and to actively
control the DAA power dissipation.
Modem functions operate in response to data modem and V.80 AT commands and
S Register parameters (Table 1-3). See AT Commands for CX84100-41/-23 SCXV.22bis
Modem Reference Guide (Doc. No. 102338) for a complete description of the commands
and registers.
