ETH-FE1
11
For E1 bandwidth selection, Effective only if the encapsulation mode is set to 'HDLC' (i.e. GFP /
HDLC switch is set to 'ON'), the DIP Switch settings on the right side panel are as follows:
Working Mode
Switch Setting
TS0
TS1-15, 17-31
TS16
Unframed / PCM 31
ON
ON
ON
Framed (CCS) / PSM 31
OFF
Occupied timeslot ON
Multi Framed (CAS) / PCM 30
OFF
Occupied timeslot ON
OFF
Example 1:
If you wish to use only first 5 time slots then you need to set the TS0 time slots to OFF
and switch TS1 to TS5 to ON and time slot TS16 will be set to ON.
Example 2:
If you wish to carry first 8 time slots on 512Kbps, then you need to set the TS0 time slot
OFF and switch TS1 to TS8 to ON (i.e. since each time slot consumes 64Kbps, so 8
time slots will consume 8 x 64Kbps = 512Kbps) and time slot S16 will be set to ON.
Example 3:
If you wish to carry 20 time slots on 1.28Mbps (64Kbps x 20) then you need to
set time slot TS0 OFF and TS1 to TS21 time slots to ON. Please remember that the
time slot TS16 will be used as signaling time slot.
