Transmit framer disabled.
(TABORT = 1)
Transmit framer enabled to
search TPCMI for
embedded framing.
(EMBED = 0, TABORT = 0)
Transmit framer enabled to
search TNRZ (after TSLIP
buffer) for embedded
framing. (EMBED = 1,

TSB timebase slaved to system bus TFSYNC or TMSYNC.
TSB timebase slaved to system bus TMSYNC. TFSYNC is unused.
TSB timebase slaved to system bus TFSYNC. TMSYNC is unused
and multiframe alignment is arbitrary.
SB timebase slaved to system bus TFSYNC. TMSYNC alignment is
arbitrary.
TSB timebase alignment is arbitrary.
TSB timebase slaved to system bus TMSYNC. TFSYNC aligns to
TMSYNC input.
TSB timebase is aligned to embedded framing on TPCMI. TPCMI
must be configured to line rate for this case.
TSB timebase is aligned to embedded framing on TNRZ data.
TMSYNC is unused. TPCMI may be configured for 1,544 kbps or a
multiple of 2,048 kbps.
RSB timebase slaved to system bus RFSYNC or RMSYNC.
RSB timebase slaved to system bus RFSYNC. RMSYNC alignment
is arbitrary.
RSB timebase slaved to system bus RMSYNC. RFSYNC aligns to
TMSYNC input.
RFSYNC and RMSYNC alignment is arbitrary.
RSB timebase slaved to system bus RFSYNC. RMSYNC is aligned
with the RX timebase and can follow a change of RX multiframe
alignment without generating an alarm indication.
RMSYNC is aligned with the RX timebase and can follow a change
of RX multiframe alignment without generating an alarm
indication. RFSYNC is aligned to RMSYNC.
