Unchannelized Mode.
It is the user’s responsibility to configure the time slot map to contain one time slot.
T1 mode.
This mode implies 24 time slots and T1 signaling. It is the user’s responsibility to
configure the time slot map to contain exactly 24 time slots.
Nx64 mode = 2 Time Slots
It is the user’s responsibility to configure the time slot map to contain exactly two time
slots.
Nx64 mode = 3 Time Slots
It is the user’s responsibility to configure the time slot map to contain exactly three time
slots.
Nx64 mode = 4 Time Slots
It is the user’s responsibility to configure the time slot map to contain exactly four time
slots.
Nx64 mode
It is the user’s responsibility to configure the time slot map to contain more than four
time slots.
TSBUS Mode
It is the user’s responsibility to configure the time slot map to contain at least eight time
slots. For the first twelve ports this mode can also be used for DS0 extraction. This is
performed by the use of the DS0 bit in the Time Slot/Group Map. This mode is
considered to be DS0 extraction mode.
