NRZ and TDM with interface mode set to DCE.
|
You can specify the following clocking methods for NRZ
and TDM circuits with DCE mode specified:
Cfg Rate - Int Clk—Configured rate without external
TX clock (TT). The CTP device synthesizes the rate that is used on
the ST and RT outputs to the attached device. The ST is used to sample
Send Data from the attached DTE. The clock is created by the CTP DDS
circuitry and logic. This option is commonly used on circuits that
are less than 1 Mbps.
Cfg Rate - Ext Clk—Configured rate with external
TX clock (TT). The CTP device synthesizes the rate that is used on
the ST and RT outputs to the attached device. The clock is created
by the DDS circuitry and logic. This option is used to sample Send
Data from the attached device. It assumes that the attached device
is using ST or clock reference that is traceable to CTP reference.
It is typically used for higher data rates (>1 Mbps) and long cables.
All Clock - Ext Clk—All clocked with external TX
clock (TT). The CTP clock uses the external TT timing from the DTE
for all clocking. Ext TT is used to sample Send Data from the attached
device, to generate the RT clock, and to clock data into the IP network.
Adap Rate - Ext Clk—Adaptive clocking with external
TX clock (TT).
Adap Rate - Int Clk—Adaptive clocking with internal
clock.
Auto Rate - Int Clk—Autobaud rate with internal
clock.
Auto Rate - Ext Clk—Autobaud rate with external
clock.
TDM/TDC Interleaved Slow Port—Available only on
odd-numbered ports. Use this option for the low-speed port of a time
domain correlation (TDC) circuit.
Custom—The custom clocking configuration is used.

NRZ and TDM with interface mode set to DTE
|
You can specify the following clocking methods for NRZ
and TDM circuits with DTE mode specified:
Custom—The custom clocking configuration is used.
DTE, All Clocked by Ext Clk (ST/RT)—The DCE equipment
provides all clocks. The ST input clock is used to clock out the external
transmit clock (TT) and the send data (SD). The RT input clock is
used to clock in the receive data (RD).
DTE, All Clocked by User Clk(RT)—The DCE equipment
provides all clocks. The RT input clock is used to clock out the external
transmit clock (TT) and the send data (SD) and to clock in the receive
data (RD).

ISOCH
|
You can specify the following clocking methods for ISOCH
circuits:
ISOCH - Master End—This end of the circuit generates
a clock signal and sends it to the remote end. Configure ISOCH
- Slave End at the remote end.
ISOCH - Slave End—This end of the circuit uses adaptive
clocking to receive the clock signal from the remote end. The client
clock uses its period to determine when to sample data and how to
transmit data across the link.
If you specify client end, the adaptive clocking configuration
appears.
Custom—The custom clocking configuration is used.

CDI
|
You can specify the following clocking methods for CDI
circuits:
CDI - Master End—This end of the circuit generates
a clock signal and sends it to the remote end. Configure CDI -
Slave End at the remote end.
CDI - Slave End—This end of the circuit uses adaptive
clocking to receive the clock signal from the remote end. The client
clock uses its period to determine when to sample data and how to
transmit data across the link.
If you specify CDI-Slave End, the adaptive clocking configuration
appears.
Custom—The custom clocking configuration is used.

TRANS
|
You can specify the following clocking methods for TRANS
circuits:
TRANS - Master End—This end of the circuit generates
a clock signal and sends it to the remote end. Configure TRANS
- Slave End at the remote end.
TRANS - Slave End—This end of the circuit uses adaptive
clocking to receive the clock signal from the remote end. The client
clock uses its period to determine when to sample data and how to
transmit data across the link.
If you specify TRANS - Slave End, the adaptive clocking configuration
appears.
Custom—The custom clocking configuration is used.
