Egress Clock (ECLK[1:28]). When the Clock
Master mode is active, ECLK[x] is an output
and is used to sample the associated egress
data, ED[x]. ECLK[x] is a version of the
transmit clock[x] which is generated from the
receive clock or the common transmit clock,
CTCLK.
When in Clock Master: NxChannel mode,
ECLK[x] is gapped during the framing bit
position and optionally for between 1 and 23
DS0 channels or 1 and 32 channel timeslots in
the associated ED[x] stream. When Clock
Master: Clear Channel is active ECLK[x] is not
gapped.

Egress Frame Pulse (EFP[1:28]). When the
Clock Slave: EFP Enabled mode is active, the
EFP[1:28] outputs indicate the frame
alignment or the superframe alignment of
each of the 28 framers.

EFP[x] is updated on the active edge of

CECLK.
Egress Signaling (ESIG[1:28]). When the
Clock Slave: External Signaling mode is
active, the ESIG[1:28] input carries the
signaling bits for each channel in the transmit
data frame, repeated for the entire superfram’.
Each channel’s signaling bits are in bit
locations 5,6,7,8 of the channel and are
frame-aligned by the common egress frame
pulse, CEFP.
ESIG[x] is sampled on the active edge of
CECLK.
