This variable is a bitmap of the X21 Line ALarms on the FRSM-HS1. A value of zero indicates no alarms. Itemized below are the individual bits: BitPosition Alarm ----------- ----- 0 C/I signal is OFF (also used to indicate LOS) 1 Clock rate mismatch (used in DTE mode) 2 Internal Loopback (diagnostic loopback) 3 HSSI Local LoopA (line is in loopback) 4 HSSI Local LoopB (line is in loopback) 5 Remote Loopback (line is transmitting loopcodes) 6 For V35 DTE mode, DCD and CTS both are inactive 7 For V35 DCE mode, RTS is inactive 8 No cable attached to V35 backcard 9 Wrong cable attached to V35 backcard If all the bit-states are 0s: - line is not in alarm, or - line not in loopback, or - line is transmitting any loopback codes.
