0) ~133 ft
1) ~266 ft
2) ~399 ft
3) ~533 ft

7) -22.5dB CSU
Clock Source Displays the type of clocking for the port.
CTP is Clock Source—The PBX either returns the clock received from the CTP or it returns a clock that
is traceable to the same source as the CTP node clock reference. You typically use this configuration
when you configure the CTP device with a clock reference input.
CTP is Loop Timed—The PBX provides the clock and the CTP returns the same clock to the PBX. You
typically use this configuration when the PBX has the more accurate clock source. You can configure
the far end of the circuit with adaptive clocking to recover this clock if necessary.
CTP is Clock Source (Adaptive End)—The PBX returns the clock received from the CTP, and the CTP
uses the adaptive recovered clock. You typically use this configuration when the CTP does not have
a reference input and the PBX typically requires clock from the distant PBX.
On CTP150 devices, If you set clocking to CTP is Clock Source (Adaptive End), the first bundle activated
on the interface is assigned as the adaptive master bundle on which the transmit clock is adjusted.
This bundle is also the last bundle to be deactivated on the interface.
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)
