The MP1570A is an analyzer designed for the manufacturing, construction, maintenance, and
inspection of SONET, SDH, PDH, and ATM equipment and networks. Various plug-in units available
for the MP1570A allow the user to construct various analysis systems for different applications.
The MP1570A has six slots to connect the plug-in units required for SDH and SONET tests at bit rates
from 1.5 Mbps to 10 Gbps. Also ATM, jitter, and wander tests can be done by appropriate
combinations of plug-in units. The MP1570A conforms to the ITU-T and Bellcore standards and
supports concatenation mapping, tandem connection, APS measurement, and CID measurement. The
user can measure 10 Gbps signals using a single MP1570A; conventionally, this required multiple
pieces of measurement equipment.
The MP1570A has a printer and a 3.5-inch floppy disk drive as standard output devices. The user can
print the measurement results, save and read data to and from a floppy disk, and read measurement data
on an external personal computer. The user can also save screen data to a floppy disk. The MP1570A
has a function to help the user understand the analyzer operations and functions and the connection
methods.

Conforming to bit rates from 1.5Mbps to
10 Gbps with a single unit
The MP1570A conforms to ITU-T Recommendations
G.703 (2, 8, 34, 139, 1.5, and 45 Mbps) and G.703 and
G.958 (52, 156, 622, 2,488, and 9,953 Mbps), allowing
the user to select plug-in units for different applications,
including SDH, ATM, and jitter tests.
Frequency and optical power
measurement
The MP1570A can measure received frequencies and
display measurement results in a graph. If an optical
interface plug-in unit is installed, the MP1570A can
measure the absolute and relative values of optical
power.
Concatenation mapping
The MP1570A can perform SDH and SONET tests
through the mapping routes from STM-1C to STM-64C.
Enhanced SDH and SONET test
functions
The MP1570A supports the generation and detection of
CID patterns (ITU-T Recommendation G.958), tandem
connection patterns (ITU-T Recommendation G.707),
and no-frame patterns and the setting and resetting of
conditions for an APS switch time test (ITU-T
Recommendations G.707, G.783, and G.842), overhead
test, and alarm detection.
Frame memory and capture (optional)
The MP1570A can be used to edit and analyze up to 64
frames of data (or up to 26 frames of data at 10 Gbps).
Enhanced through-modes
The MP1570A allows the user to select one of four
through modes: transparent through,
overhead/over-write, payload/overwrite, and
add/drop. The user can also insert various kinds of
error and alarm signals into through signals.
Jitter generation and measurement
The MP1570A can measure jitter tolerance and jitter
transfer characteristics in conformance with ITU-T
Recommendations G.823, G.824, G.825, and G.958 and
Bellcore 253 and 499. It displays measurement results
as numeric values and in a graph, allowing the user to
evaluate them easily.
Wander generation
The MP1570A can generate wander signals in
conformance with ITU-T Recommendations G.823,
G.824, and G.825 and Bellcore 253 and 499. If a
separately sold application program is installed on the
external personal computer connected, evaluation of
MTIE and TDEV is possible.
ATM pattern generation and
measurement
The MP1570A can not only test cell performance but
also measure cell delay time, CDV, and cell traffic. For
OAM testing, it can generate and detect the AIS, RDI,
and continuity check cells for F4 and F5 flows. It can
also generate the loopback and performance-monitoring
cells which conform to ITU-T Recommendation I.610.
Error analysis (error performance)
The MP1570A enables the user to perform
measurement conforming to ITU-T
Recommendations G.821, M.2100, G.826, M.2101,
M.2110, and M.2120.
Supporting SDH, SONET, and Japan
modes with one cabinet (optional)
The MP1570A allows the user to set up the
measurement of SDH, SONET, 384k, and Japan
mapping with one cabinet. For Japanese mapping
measurement, the user can set a signaling pattern
(multi-frame pattern of 8 frames or 64 frames).

SONET, SDH, and PDH Measurement
Measurement at bit rates from
1.5 Mbps to 10 Gbps
The user can set a mapping route with a bit
rate of up to 10 Gbps. The MP1570A mainly
supports SDH, SONET, and Japanese
mapping for digital communication. A route
from STM-1C to up to STM-64C can be set
for concatenation mapping. Furthermore, the
MP1570A supports a combination of channels
-- for example, one channel of VC4, 16
channels of STM4C, and four channels of
STM16C. (See fig.1/P.10)
Overhead setting and testing
The user can set overhead, modify the capture and
overhead settings, and measure pointer 64 frames
and overhead bit errors.
4
APS function
The user can test the automatic protection
switch (APS) by measuring the equipment
switching time accurately in units of
milliseconds. The MP1570A also conforms to
ITU-T Recommendations G.783 and G.841.
Mixed payload
At measurement of mapping in TUG-3 and lowerÂlevel layers, the user can set two additional
channels other than the measurement-target
channels.
Tandem connection
The user can set and measure N1 and N2 bytes.
5
Various analysis functions
The MP1570A has an internal optical power meter which
allows the user to measure optical power during error and
alarm measurement without changing the connections of
the optical fiber cables. (Photo A)
The MP1570A can capture an arbitrary SOH or POH (1
byte), K1 or K2 byte, or H1 or H2 byte in 1,024 frames
for analyzing errors and alarms and for checking APS
operation. (Photo B)
Measured errors and alarms can be displayed in a graph.
The user can select a unit time of 1 second, 1 minute, 15
minutes, or 60 minutes for a bar graph. (Photo C)

Pointer value monitoring

The MP1570A can display changes of pointer
value in a graph. Monitored values are updated
in real time.
MUX/DEMUX function (optional)
The MP1570A allows the user to set frames on or off at every bit rate. If the MUX/DEMUX function
is installed, the MP1570A can generate a multiplexing structure including frame alignment signals and
perform multiplexer/demultiplexer measurement.
