4.2.2
In unchannelized mode the complete incoming and outgoing serial bit stream belongs to
one logical channel. Although unchannelized mode does not have a time slot scheme,
this mode is handled internally the same way as a port configured in T1 mode. Therefore
the time slot assignment must be done as in T1 mode, with exception that ‘time slots’
zero to 23 must be assigned to one channel and that no time slot may be set to inhibit.
The function of bit masks, which is available in T1, E1, 4.096 MHz or 8.192 MHz mode,
is not available in unchannelized mode. Each bit of the time slots 0-23 must be enabled,
setting the masks to FF
function of synchronizing bits to an external frame synchronization pulse.
Data Sheet
Example configuration:
Port three in mode E1.
Timeslot 2 and 3 are assigned to channel 5.
Bit 0 of timeslot 2 and bit 1 of timeslot 3 are masked.
