2.7 Synchronous Payload Envelope Mapper
(SPEMPR) (x6)
The SPE mapper accepts/delivers TUG-2 data from/to
the VT mapper. The TUG-2 data is mapped/demapped
either to/from an AU-3/STS-1 signal for the North Ameri-
can digital systems or to/from a TUG-3 signal for the
ITU-
based systems. Only available for SPEMPR 0—2.
The SPE mapper accepts/delivers channelized DS3 data
from/to the M13 MUX/deMUX. The DS3 data is mapped/
demapped either to/from an AU-3/STS-1 signal for the
North American digital systems or to/from a TUG-3 signal
for the
ITU-based
systems. Only available for
SPEMPR 3—5.
The SPE mapper accepts/delivers channelized or
unchannelized DS3 signals at a 44.736 Mbits/s rate from
external I/O. The DS3 signals are mapped/demapped
the same way as the M13 signal described above.
The SPE mapper accepts/delivers channelized E3 data
from/to the E13 MUX/deMUX. The E3 data is mapped/
demapped either to/from an AU-3/STS-1 signal for the
North American digital systems or to/from a TUG-3 signal
for the
ITU-based
systems. Only available for
SPEMPR 3—5.
The SPE mapper accepts/delivers channelized or
unchannelized E3 signals at a 34.368 Mbits/s rate from
external I/O. These E3 signals are mapped/demapped
the same way as the E13 signal described above.
The SPE mapper has a DS3/E3 loopback circuit placed
to demap and remap a DS3/E3 signal. It is particularly
useful in cases where a DS3/E3 signal, mapped as an
AU-3/STS-1 signal, requires remapping as a TUG-3 sig-
nal or vice versa.
The SPE mapper supports a path overhead access
channel (POAC). Seven path overhead bytes (J1, C2,
F2, H4, F3, K3, and N1) can be inserted/dropped through
this channel. This channel works as the master, meaning
it provides a clock in both the transmit and receive direc-
tions and POH data can be inserted on the transmit side
or dropped on the receive side.
Path overhead byte B3 (BIP error) generation/detection
and programmable BIP-8 bit error rate insertion.
Signal fail and signal degrade indicators available to
report bit error rates above standard provisionable
thresholds.
Capable of detecting/inserting AIS, RDI, and REI.
Monitoring is provided on all the TUG-3 path overhead
bytes.
N1 tandem connection support is provided.
TUG-3 pointer processor supports add/drop multiplexing.

2.5 Mate Clock and Data Recovery (MCDR) (x1)
Provides glueless capability to connect
UltramapperLites
in a master/slave configuration.
Loss-of-clock detection from the three external
155.52 MHz clock inputs.
Loss-of-frame (LOF), out-of-frame (OOF), and B2 error
detection on the three 155.52 Mbits/s interfaces. Also
RDI and REI monitoring and generation is available.
Manual B2 error insertion for debugging.
Provisionable delay between output data frame and
8 kHz sync to accommodate variable length paths to
slave
UltramapperLites.
2.6 STS-1 Line Terminating (STS1LT) (x3)
Supports standard SPE mappings for sub-STS-1 pay-
loads (VT-mapped: 28 DS1, 28 J1, or 21 E1 signals).
Supports standard SPE mappings for STS-1 payloads
(DS3/E3).
Detects STS-1 loss-of-signal (LOS), out-of-frame (OOF),
loss-of-frame (LOF), AIS-P, and LOP conditions.
Provides STS-1 selectable scrambler/descrambler func-
tions and B1/B2/B3 generation/detection.
Provides STS-1 pointer interpretation/processing.
Complies with GR-253-CORE, T1.105, G.707 (March
1996), G.783, G.826, G.821, and ETSI 417-1-1.
