Unit Type

Selects the unit type. TU-R represents a CPE terminal unit; TU-C represents a

CO terminal unit. The TU-C mode is for back-to-back operation needed for

E1 replacement applications.

Values:

TU-R, TU-C

Default:

TU-R

Timing (Tx/Rx)

Sets the transmit and receive timing source to synchronize the unit’s internal

timing generators. In all cases, slips are controlled to occur on frame

boundaries at the network port when timing synchronization is lost. Choices

are as follows:

Internal –

The unit’s internal frequency standard is used for all timing.

SHDSL –

Timing is derived from the network recovered clock. Most

applications use this selection. (Default)

Serial –

The Transmit clock is sourced from the Nx64k and the Receive clock

is the SHDSL port recovered clock.

G.703 –

The Transmit clock is sourced from G.703 and the Receive clock is

the SHDSL port recovered clock.

Valid Timing options depend on the selected unit type:

For STU-C:

Values:

Internal/Internal, G.703/G.703, Serial/Serial

Default:

Internal/Internal

For STU-R:

Values:

SHDSL/SHDSL

Default:

SHDSL/SHDSL
