TUPP™ 2488 ASSP Telecom Standard Product Data Sheet
Function
Line Egress Connection Memory Page. The line
egress connection memory page select signal
LECMP, in combination with an internal register bit,
controls the selection of the connection memory
page in the egress line side Time Slot Interchange
blocks. LECMP 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.
LECMP is sampled at the J0(C1) byte position of
every frame on the egress 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 LECMP is
sampled).
LECMP is sampled on the rising edge of REFCLK.
System Egress Connection Memory Page. The
system egress connection memory page select
signal, SECMP, controls the selection of the
connection memory page in the egress system
Memory Switch Units. When SECMP is set high,
connection memory page 0 is selected. When
SECMP is set low, connection memory page 1 is
selected.
SECMP is sampled at the J0(C1) byte position of
every frame on the egress bus. Changes to the
connection memory page selection are
synchronized to the frame boundary (A1 byte
position) of the next frame.
SECMP is sampled on the rising edge of REFCLK.
