If the timeslot 0 is used to transmit payload data in additional (service) bit
positions, it may also be included to the list of transmitted timeslots:

:
3.5.5.2 Timeslot 16
The timeslot 16, conforming to G.704 recommendation, is reserved for
signaling.
The timeslot 16 must be included in a list of transmitted timeslots
regardless of other timeslots if equipment connected by the modems
requires a signaling channel, e.g. telco devices.

Used timeslots: 6 Payload: 384 kbit/s
:
In the example above the timeslots 3 through 7 are used to carry voice
channels and the timeslot 16 is used to transmit signaling. The modem
recognizes all those timeslots as payload data, so the required DSL rate is
384 kbps.
