7.1.3 DSL Configuration (Tabletop)
There is only one DSL interface available on the tabletop modem. The DSL configuration com-
mands are somewhat simplified.
BACKOFF ON | OFF
Set SHDSL Power Back-Off function ON / OFF.

LINERATE n i a
Set line rate:
Parameters:
n denotes the number of DSL timeslots to be transmitted (3 ≤ n ≤ 36)
i 1 denotes the Z-bits automatically used to increase the EOC bandwidth of about 3.2
kbit/s by 8 kbit/s (i = 0 or 1, default i =1 )
a 1 denotes asymmetric PSD operation.
Notes
! The LINERATE command is only available if the modem is acting as a DSL master (MASTER
ON). If the modem is configured as DSL slave then the linerate is set by the master.
! Use of Z-bits for the EOC and asymmetric PSD operation is provided for compatibility of the
Watson 5 Ethernet tabletop with TDM-based Watson 5 modems, cf. [1]. The Watson 5 Ethernet
plugin does not support these features.
MASTER ON | OFF
Set DSL master mode ON/OFF.
MODE 1 | 2
Select DSL operating mode:
1: 1 pair operation
