Contiguous Concatenations
enhancement
Enhancement of contiguous
concatenations allows you to test the
breadth of GR-253/ G.707.
• STS-3c, 6c, 9c, 12c, 24c and 48c
• AU-3, AU-4, AU-4-2c, AU-4-3c,
AU-4-4c, AU-4-8c, AU-4-16c
• PRBS within the concatenated
payloads
• Support of GFP/LAPS as the
concatenated payloads
Mixed mappings
Support for mixed mappings now allows
convenient setup of complex structures
resulting in reduced test times
• Two convenient configuration modes
- Preset (simple background selection)
- Mixed mappings (mixed background
selection)
• Configure any combination of valid
positions
• Any channel can be set as Foreground
• Foreground channel can be virtually
concatenated
• Background channels can be either
- Equipped
- Unequipped
- AIS
DSn/PDH testing
The DSn/PDH test capability allows
comprehensive testing of DSn/PDH
signals and networks with the following
interfaces: DS1 (1.5 Mb/s), DS3 (45
Mb/s), 2 Mb/s, 8 Mb/s, 34 Mb/s and 140
Mb/s. Supported functionality includes:
• Unframed, framed, and structured
(mux/demux) testing
• Error and alarm generation and
detection
• 56 kb/s, n x 56 kb/s, 64 kb/s and n x
64 kb/s testing
• Drop-Insert DSn/PDH to/from
SONET/SDH
• Drop-Insert DS1/2Mb/s to/from
DSn/PDH
• DS1 loop codes and DS3 FEAC
messages
• PDH spare-bits control and monitoring
• Performance analysis G.826, G.828,
G.821, M.2101, M.2101.1, M.2110,
M.2120
Additional measurements
• Optical power
• Line frequency
• Pointer measurements
•Servicedisruption
• Virtual concatenation differential delay
measurement
SONET/SDH Virtual
Concatenation
Verify virtual concatenation of high and
low order payloads with delay generation
across the full ITU-T G.707 256ms range.
Realistic traffic with full Ethernet payload
mapped via GFP or LAPS.
• High order concatenation of
STS-3c/STS-1/AU-4/AU-3
• Low order concatenation of
VT2/VT1.5/ TU-3/TU-12/TU-11
• Flexibility to specify which members
form the group and add delay to each
member
• Group overview simultaneously
monitors all group members
• Discovery function automatically
detects virtual concatenation
members
• Fine delay adjustment to see exactly
when input buffers fail
• Coarse delay adjustment allows
performance under transients to be
verified.
• Full alarm and error generation and
detection
SONET/SDH testing
SONET/SDH capability allows
comprehensive testing of synchronous
networks with the following interface
rates: 2.5 G/s, 622 Mb/s, 155 Mb/s and 52
Mb/s. Supported functionality includes:
• Framed/unframed testing at all rates
• SONET/SDH error and alarm
generation and detection
• Setup and monitor all overhead bytes
• Alarm stress testing with 'p', 'n', and
'm' sequences
• Overhead sequence generation and
capture
• Entire overhead capture (no payload
capture)
• Transmit and receive error and alarm
event trigger outputs
• Through mode test capability
- Transparent through mode
- Overhead overwrite - add
errors/alarms
