CES Transmit Clock

To ensure that the ACR clock tracing is accurate in certain scenarios, you need to extract the clock transmitted in the upstream service from the master CES service and bind the clock to the CES service. On this user interface, you can add, query, and delete the E1 clock, and set the binding relationship between the CES service and E1 clock.

Background Information

Generally, the master NE transmits service clock signals to the slave NE by using the ACR clock. In certain scenarios, if the CES service board carried on the master NE is the MP1, VS2, or CD1 board of the RTN 905E or the CQ1 board of the RTN 9X0, OSN 5X0 or OSN 18II, and the CES service board carried on the slave NE is the MP1, VS2, or CD1 board of the RTN 905E, you need to create an E1 clock and bind it to the master CES service. This helps improve clock accuracy of the slave NE.

Navigation Path

In the NE Explorer, choose Configuration > Click > CES Transmit Clock from the Function Tree.

Parameter Description

Domain	Value	Description
Clock Board ID	For example: 1-CQ1	Displays the logical board ID of an NE. NOTE: The RTN 905E has no board ID and is displayed as -.
E1 Clock ID	1 to 12	Displays the E1 clock ID.
Port ID	For example: 1-CQ1-1(PROT-1)	Displays the port ID of an NE.
High Channel ID	VC4 supported by a board	Allows you to set the VC4 higher-order channel number.
Lower Channel ID	Lower-order timeslot supported by a board or tributary port number	Allows you to set the lower-order channel number. If the port is an E1 port, set the E1 port ID. If the port is a channel port, set the VC12 lower-order channel id.
CES Service ID	For example: 5	Displays the CES service ID.
Service Name	For example: CES service	Displays the CES service name.

E1 Clock Button Description

Button	Description
Query	Queries an E1 clock that is added.
New	Creates an E1 clock.
Delete	Deletes an E1 clock.

CES Service Button Description

Button	Description
Query	Queries the CES service that is created and the binding relationship between the CES service and E1 timeslot.
New	Creates a binding relationship between an E1 clock and a CES service, that is, the E1 clock is used instead of the system clock as the CES service clock.
Delete	Deletes the binding relationship between the E1 clock and CES service, that is, the system clock is used instead of the E1 clock as the CES service clock.
