Layout in a NeXspan S (main cabinet only)
Figure 4-11: Slot numbers on the backplane of an XS switch
An LD4/LD4NX card with or without ADPCM16 daughter card can be fitted in slots 00, 01 and
02.
Note:
The three slots are synchronising positions. H0 in position 00 has priority over H1, H2
and H3 (retrieved from the T0 interfaces built into the UCT-S card) which have the same
priority.
Installation in a NeXspan S12 (no expansion cabinet)
•
Non-rackable NeXspan S12: by default no expansion card (optional backplane)
•
Rackable NeXspan S12: 3 slots numbered 00 to 02.
Figure 4-12: Slot numbers on the backplane of an XS12
An LD4/LD4NX card with or without ADPCM16 daughter card can be fitted in slots 00, 01 and
02.
Note:
On an XS12 PBX, the back plane does not send network synchronisation (synchronising
positions are the T0 interfaces integrated into UCT). Therefore, the XS12 PBX cannot
receive LT2, LD4, LD4NX type synchronising cards with the T0 function.
