NAME AND DESCRIPTION
ESMDM
CCR3.7
Elastic Store Minimum Delay Mode. See Section 10.3 for
details.
0 = elastic stores operate at full two-frame depth
1 = elastic stores operate at 32-bit depth
ESR
CCR3.6
Elastic Store Reset. Setting this bit from a 0 to a 1 will force the
elastic stores to a known depth. Should be toggled after
RSYSCLK and TSYSCLK have been applied and are stable.
Must be cleared and set again for a subsequent reset.
RLOSF
CCR3.5
Function of the RLOS/LOTC Output.
0 = Receive Loss of Sync (RLOS)
1 = Loss of Transmit Clock (LOTC)
RSMS
CCR3.4
RSYNC Multiframe Skip Control. Useful in framing format
conversions from D4 to ESF. This function is not available when
the receive side elastic store is enabled.
0 = RSYNC will output a pulse at every multiframe
1 = RSYNC will output a pulse at every other multiframe
note: for this bit to have any affect, the RSYNC must be set to
output multiframe pulses (RCR2.4=1 and RCR2.3=0).
PDE
CCR3.3
Pulse Density Enforcer Enable.
0 = disable transmit pulse density enforcer
1 = enable transmit pulse density enforcer
ECUS
CCR3.2
Error Counter Update Select. See Section 5 for details.
0 = update error counters once a second
1 = update error counters every 42 ms (333 frames)
TLOOP
CCR3.1
Transmit Loop Code Enable. See Section 12 for details.
0 = transmit data normally
1 = replace normal transmitted data with repeating code as
defined in TCD register
-
CCR3.0
Not Assigned. Must be set to 0 when written.
Pulse Density Enforcer
The SCT always examines both the transmit and receive data streams for violations of the following rules
which are required by ANSI T1.403:
-
no more than 15 consecutive 0s
-
at least N 1s in each and every time window of 8 x (N +1) bits where N = 1 through 23
Violations for the transmit and receive data streams are reported in the RIR2.0 and RIR2.1 bits
respectively. When the CCR3.3 is set to 1, the DS2152 will force the transmitted stream to meet this
requirement no matter the content of the transmitted stream. When running B8ZS, the CCR3.3 bit should
be set to 0 since B8ZS encoded data streams cannot violate the pulse density requirements.
