TMSYNC
Explanation
IN
TSB timebase slaved to system bus TFSYNC or TMSYNC.
IN
TSB timebase slaved to system bus TMSYNC. TFSYNC is unused.
IN-GND
TSB timebase slaved to system bus TFSYNC. TMSYNC is unused
and multiframe alignment is arbitrary.
OUT
SB timebase slaved to system bus TFSYNC. TMSYNC alignment is
arbitrary.
OUT
TSB timebase alignment is arbitrary.
IN
TSB timebase slaved to system bus TMSYNC. TFSYNC aligns to
TMSYNC input.
OUT
TSB timebase is aligned to embedded framing on TPCMI. TPCMI
must be configured to line rate for this case.
IN-GND
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.
RMSYNC
Explanation
IN
RSB timebase slaved to system bus RFSYNC or RMSYNC.
OUT
RSB timebase slaved to system bus RFSYNC. RMSYNC alignment
is arbitrary.
IN
RSB timebase slaved to system bus RMSYNC. RFSYNC aligns to
TMSYNC input.
OUT
RFSYNC and RMSYNC alignment is arbitrary.
OUT
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.
OUT
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.
