Table 57: CTP Bundle Runtime State and Counters in CTPView (continued)
Field Name
Field Description
Port Runtime Flags
Displays the current configuration of BERTs and serial loops.
Inactive—No activity is detected on the serial input. The activity detector checks the serial input line
every 500 milliseconds for any transitions on the line. Port Run Time flag of the serial CTP bundle
shows the status as Inactive if no activity is detected on the serial input line. This flag is displayed
only when the serial input line is inactive, which is an abnormal condition. No such flag is displayed
if the serial input line is active.
This flag applies only to a serial port that has a T1E1 DCARD installed and is in use. It does not apply
to ports on a T1E1 card.
BertFrmNet—Used to receive the BERT from the network
BertFromIf—Used to receive the BERT from the interface
BertToNet—
BertToIf—
LoopToNet—Used to loop back the BERT to the network
LoopToIf—Used to loop back the BERT to interface
IRIG-B Run Flags
Displays the current status of the IRIG-B runtime
TxIpSync—Transmit mode is in sync with the remote CTP device.
TxSyncLost—Transmit mode is not in sync with the remote CTP device.
RxIpSync—Receive mode is in sync with the remote CTP device.
RxSyncLost—Receive mode is not in sync with the remote CTP device.
T1E1 flags
Appears for bundles on T1/E1 interfaces.
LOS—Loss of signal. This could mean that the cable is not attached. When LOS is detected, the
CTP device puts the bundle into a loop so that the TX and RX clock are looped to each other.
LOF—Loss of frame.
AIS—Alarm indication signal.
RAI—Remote alarm indication (yellow alarm).
LOF_NB—Fractional T1 only. FPGA framer loss of frame network bound.
LOF_IB – Fractional T1 only. FPGA framer loss of frame interface bound.
TT (Ext Clock)
Displays the current speed of the transmit timing (TT) clock.
The TT measurement is displayed only for a CTP bundle or a SAToP bundle that is attached to a T1E1
port on a T1E1 Daughter Card or a CTP bundle attached to a serial port with clock configuration set to
Configured with TT, All Clocked by TT, Adaptive Rate, w/ User Clk (TT), or Autobaud Rate, w/ User
Clk (TT).
RT (Ext Clock)
Displays the current speed of the receive timing (RT) clock.
Appears if the bundle is configured as the DTE, and clocking is set to DTE, All Clocked by Ext Clk
(ST/RT) .
Adaptive State
For bundles that are configured as the adaptive end for adaptive clocking, displays the current state
of the adaptive clock:
