U n it Typ e 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
T im in g (T x /R x ) 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
