Bit 0/Receive Remote Alarm Condition (RRA) (E1 Only). Set when a remote alarm is received at RPOSI and
RNEGI. This is a double interrupt bit. See Section 6.3.
Bit 1/Receive Distant MF Alarm Condition (RDMA) (E1 Only). Set when bit 6 of time slot 16 in frame 0 has
been set for two consecutive multiframes. This alarm is not disabled in the CCS signaling mode. This is a double
interrupt bit. See Section 6.3.
Bit 2/V5.2 Link Detected Condition (V52LNK) (E1 Only). Set on detection of a V5.2 link identification signal
(G.965). This is a double interrupt bit. See Section 6.3.
Bit 3/Loss-of-Receive Clock Condition (LORC). Set when the RCLKI pin has not transitioned for one channel
time. This is a double interrupt bit. See Section 6.3.
Bit 4/Loss-of-Transmit Clock Condition (LOTC). Set when the TCLK pin has not transitioned for one channel
time. Forces the LOTC pin high if enabled by CCR1.0. This is a double interrupt bit. See Section 6.3.
Bit 5/Loop-Up Code Detected Condition (LUP) (T1 Only). Set when the loop-up code as defined in the
RUPCD1/2 register is being received. See Section 25 for details. This is a double interrupt bit. See Section 6.3.
Bit 6/Loop-Down Code Detected Condition (LDN) (T1 Only). Set when the loop down code as defined in the
RDNCD1/2 register is being received. See Section 25 for details. This is a double interrupt bit. See Section 6.3.
Bit 7/Spare Code Detected Condition (LSPARE) (T1 Only). Set when the spare code as defined in the RSCD1/2
registers is being received. See Section 25 for details. This is a double interrupt bit. See Section 6.3.
