SYMBOL

NAME AND DESCRIPTION
RSA1
SR1.7
Receive Signaling All Ones/Signaling Change. Set when
over a full MF, the content of timeslot 16 contains fewer than
three zeros. This alarm is not disabled in the CCS signaling
mode. A change in the contents of RS1 through RS16 from
one multiframe to the next will cause RSA1 and RSA0 to be
set.
RDMA
SR1.6
Receive Distant MF Alarm. Set when bit 6 of timeslot 16 in
frame 0 has been set for two consecutive multiframes. This
alarm is not disabled in the CCS signaling mode.
RSA0
SR1.5
Receive Signaling All Zeros/Signaling Change. Set when
over a full MF, timeslot 16 contains all zeros. A change in the
contents of RS1 through RS16 from one multiframe to the next
will cause RSA1 and RSA0 to be set.
RSLIP
SR1.4
Receive Side Elastic Store Slip. Set when the elastic store has
either repeated or deleted a frame of data.
RUA1
SR1.3
Receive Unframed All Ones. Set when an unframed all ones
code is received at RPOS and RNEG.
RRA
SR1.2
Receive Remote Alarm. Set when a remote alarm is received
at RPOS and RNEG.
RCL
SR1.1
Receive Carrier Loss. Set when 255 (or 2048 if CCR3.0 = 1)
consecutive zeros have been detected at RPOS and RNEG.
RLOS
SR1.0
Receive Loss of Sync. Set when the device is not
synchronized to the receive E1 stream.
