over 5781 provide 8+ one DTI for
each 774 ccs in excess
of 5781
ccs.
Note: In a Network module, if two network slots
are available but not contiguous, the Superloop
Network Card or Enhanced Network Card can be
moved to create a 2” slot for DTI/PRI. The
Superloop Network Card can be plugged into the
left or right half of the “superslot” to achieve this
For non-blocking applications, the Ring Again feature must be provided
since blocking may occur at the far end of the trunk.
Since the DTI/PRI Card physically occupies two network slots, therefore,
the number of DTI/PRI Cards should be multiplied by 2 to obtain the
required number of network slots.
DTI/PRI Cards can be plugged into a Network module, a
Common/Peripheral Equipment module, a Common Equipment module, a
CPU module, or Remote Peripheral Equipment modules. After all essential
cards are configured in these UEMs, estimate the available slots for
DTI/PRI. If enough slots are not available for all DTl/PRIs required, a
special DTI/PRI-only Network module can be added to the system.
