E1 Transmit Backplane Time Slot Offset (01BH, 09BH, 11BH, 19BH, 21BH, 29BH, 31BH, 39BH)
transmitted on TSDn & TSSIGn. In Transmit Multiplexed mode, the content in the TSOFF[6:0] determines the time slot offset between MTSCFS and
the start of the Basic Frame transmitted on MTSD & MTSSIG for the corresponding framer.

In Transmit Clock Slave mode, the content in the TSOFF[6:0] determines the time slot offset between TSCFS and the start of the Basic Frame
In Transmit Clock Master mode, the time slot offset is disabled, that is, the TSOFF[6:0] must be logic 0.
The TSOFF[6:0] define a binary number. The offset can be set from 0 to 127 time slots.
Valid when the CMS (b2, E1-018H) is logic 1.
= 0: The first active edge of TSCCKB/MTSCCKB is used to sample the data on TSDn/MTSD, TSSIGn/MTSSIG and to update the data on
= 1: The second active edge of TSCCKB/MTSCCKB is used to sample the data on TSDn/MTSD, TSSIGn/MTSSIG and to update the data on
(The signal on the TSCFS/MTSCFS pin is always sampled on the first active edge.)
This bit controls if the value in the BOFF[2:0] is the actual value or meets the Concentration Highway Interface (CHI) specification.
= 0: Disable the CHI specification.
= 1: Enable the CHI specification.
In Transmit Clock Master mode, the content in the BOFF[2:0] determines the bit offset between the signal on TSFSn and the start of the Basic

In Transmit Multiplexed mode, the content in the BOFF[2:0] determines the bit offset between MTSCFS and the start of the Basic Frame transmit-
These bits define a binary number. When the CHI = 0, the setting in the BOFF[2:0] is their actual value (‘0’ stands for 0 bit offset, ‘1’ stands for 1
