ALTIMER
The ALTIMER bit is used to select the time required to declare ALOS. ALTIMER = 0
selects 1 ms—2.6 ms. ALTIMER = 1 selects 10 bit—255 bit periods.
The RCVAIS bit selects the shutdown function for the receiver during analog loss of
signal alarm (ALOS). RCVAIS operates in conjunction with the LOSSD bit.
The PFLALM prevents the DLOS alarm from occurring during FLLOOP activation.
The PRLALM prevents the LOTC alarm from occurring during RLOOP activation/
deactivation.
The PHIZALM prevents the TDM alarm from occurring when the driver is in a high-
impedance state.
The JABW0 bit selects the lower bandwidth jitter attenuator option in CEPT mode.
The CODE2 bit selects B8ZS/HDB3 encoding (transmit) and decoding (receive) in
channel 2.
The CODE1 bit selects B8ZS/HDB3 encoding (transmit) and decoding (receive) in
channel 1.
