POSITION DESCRIPTION
LUP
(latched)
SR.7
Loop-Up Code Detected. Set when the loop-up code defined in registers
RUPCD1 and RUPCD2 is being received. See Section 4 for details.
LDN
(latched)
SR.6
Loop-Down Code Detected. Set when the loop-down code defined in
registers RDNCD1 and RDNCD2 is being received. See Section 4 for
details.
LOTC
(real time)
SR.5
Loss of Transmit Clock. Set when the TCLK pin has not transitioned for
5
sec (±2s). Will force the LOTC pin high.
RUA1
(latched)
SR.4
Receive Unframed All Ones. Set when an unframed all ones code is
received at RRING and RTIP. See Table 5-1 for details.
RCL
(latched)
SR.3
Receive Carrier Loss. Set when a receive carrier loss condition exists at
RRING and RTIP. See Table 5-1 for details.
TCLE
(real time)
SR.2
Transmit Current Limit Exceeded. Set when the 50mA (RMS) current
limiter is activated whether the current limiter is enabled or not.
TOCD
(real time)
SR.1
Transmit Open Circuit Detect. Set when the device detects that the TTIP
and TRING outputs are open circuited.
PRBSD
(real time)
SR.0
PRBS Detect. Set when the receive-side detects a 215 - 1 (E1) or a 220 - 1
(T1) Pseudo-Random Bit Sequence (PRBS).
