TxConfigClock

Description

Sets the clocking configuration of the MVIP/H.100/H.110 adapter.

Prototype

short TxConfigClock (short handle,
CLOCK_T clock,
SEC8K_T sec8k,
NETWORK_T network)

handle TX board number.

clock Mode for main clock signals (/C4, /F0, C2).

sec8k Source of SEC8K clock signal.

network Specifies clock reference source for master and/or SEC8K clock. Must be either NET_T1A or NET_T1B.

Return Values

Details

The TxConfigClock function specifies whether the TX board is the master or slave of the main clock signals (/C4, /F0, C2), the source of its clock circuit reference input (internal, T1/E1 interface A or B, or SEC8K clock signal), and whether or not it drives the SEC8K clock signal. This request overrides any setting specified in the tdmcfg dedicated data channel configuration file.

The following tables provide valid options for the clock and sec8k parameters, respectively:
Parameter

Description

CLOCK_REF_MVIP

TX board is slave.

CLOCK_REF_SEC8K

TX board is master, referenced from SEC8K signal.

CLOCK_REF_OSC

TX board is master, free-running from internal oscillator.

CLOCK_REF_NET

TX board is master, referenced from T1/E1 interface specified in the network parameter.

Parameter

Description

SEC8K_NOT_DRIVEN

SEC8K not driven by TX board.

SEC8K_DRIVEN_BY_OSC

SEC8K driven by internal oscillator.

SEC8K_DRIVEN_BY_NET

SEC8K driven by clock extracted from T1/E1 interface specified in the network parameter.
