configure ports tdm clock-source

configure ports port_list tdm clock-source [line | network | [adaptive | differential] ces ces_name]

Description

Configures the transmit clock source of the specified TDM port.

Syntax Description

port_list

Specifies one or more ports or slots and ports.

line

TDM line recovered clock (clock slave mode) (Default).

adaptive

Adaptive clock recovery

differential

Differential clock recovery.

network

Network clock.

ces_name

Alpha-numeric string identifying Circuit Emulation Service pseudowire recovered clock.

Default

The default clock-source is line.

Usage Guidelines

Currently the hardware limits the CES pseudowire recovered clock (Adaptive/Differential) to be supplied only to the port terminating the pseudo-wire. When the [adaptive | differential] switch is used, the backend EXOS process processing the command will return the following error message if the port_list parameter expands to multiple ports:

Error: The CES pseudo-wire <ces_name> cannot be used to supply clock to multiple ports.

The backend EXOS process processing the command will return the following error message if the port specified in the port_list parameter does not terminate the CES pseudo-wire when the [adaptive | differential] switch is used:

Error: CES pseudo-wire <ces_name> does not terminate on port specified for using Adaptive or Differential clock recovery.
