T1 - ESF 4 mode
T1 ESF 4 mode provides 24 timeslots to transport traffic using the G.704 24 frame Extended Super
Frame with four state demultiplexed signalling using the AB bits each with a bit rate of 667 bit/s.
The mapping left column is used to map timeslot bits and the timeslot table right column is used to
map the CAS A&B bits for signalling (C&D bits are not used).
T1 ESF 4 mode is used when access to the signalling bits is required, for example:
Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into a 24 frame Extended
Super Framed T1 using ‘multiplexed’ signalling from the interface.
Drop and Insert connections between 24 frame Extended Super Framed T1s or data interfaces
T1 - ESF 16 mode
T1 ESF 16 mode provides 24 timeslots to transport traffic using the G.704 24 frame Extended Super
Frame with sixteen state demultiplexed signalling using the ABCD bits each with a bit rate of 333 bit/s.
The mapping left column is used to map timeslot bits and the timeslot table right column is used to
map the CAS ABCD bits for signalling.
T1 ESF 16 mode is used when access to the signalling bits is required, for example:
Cross connecting signalling from DFXS, DFXO or Q4EM interfaces into a 24 frame Extended
Super Framed T1 using ‘non-multiplexed’ signalling from the interface.
Drop and Insert connections between 24 frame Extended Super Framed T1s or data interfaces
