TUPP™ 2488 ASSP Telecom Standard Product Data Sheet
Function
Line Ingress Connection Memory Page. The line
ingress connection memory page select signal
LICMP, in combination with an internal register bit,
controls the selection of the connection memory
page in the ingress line side Time Slot Interchange
blocks. LICMP is logically XORed with the internal
page select bit and the result is used to select the
active connection memory page. When this result
is set high, connection memory page 1 is selected.
When this result is set low, connection memory
page 0 is selected.
LICMP is sampled at the J0(C1) byte position of
every frame on the ingress bus. Changes to the
connection memory page selection are
synchronized to the frame boundary (A1 byte
position) of the frame following the next transport
frame (i.e. two frame boundaries after LICMP is
sampled).
LICMP is sampled on the rising edge of REFCLK.
System Ingress Connection Memory Page. The
system ingress connection memory page select
signal, SICMP, controls the selection of the
connection memory page in the ingress system
side Memory Switch Units (MSUs) and Column
Crossbar Switch (CCB). When SICMP is set high,
connection memory page 0 is selected in the MSUs
and connection memory page 1 is selected in the
CCB. When SICMP is set low, connection memory
page 1 is selected in the MSUs and connection
memory page 0 is selected in the CCB.
SICMP is sampled at the J0(C1) byte position of
every frame on the ingress bus. Changes to the
connection memory page selection are
synchronized to the frame boundary (A1 byte
position) of the next frame.
SICMP is sampled on the rising edge of REFCLK.
