ADDITIONAL TEST AND MEASUREMENT FUNCTIONS
Power measurements Supports power measurements, displayed in dBm (dBdsx for DS1), for optical and electrical interfaces.
Frequency measurements Supports clock frequency measurements (i.e., received frequency and deviation of the input signal clock from nominal frequency),
displayed in ppm and Gbit/s, for optical and electrical interfaces.
Frequency offset generation Supports offsetting the clock of the transmitted signal on a selected interface to exercise clock recovery circuitry on network elements.
Dual DSn receivers Supports two DS1 or DS3 receivers, allowing users to simultaneously monitor two directions of a circuit under test in parallel, resulting in quick isolation of
the source of errors.
Performance monitoring The following ITU-T recommendations, and corresponding performance monitoring parameters, are supported on the FTB-8120NGE/8130NGE.

Programmable error/alarm injection Ability to inject errors/alarms in the following modes: Manual, Constant Rate, Burst, Periodic Burst and Continuous.
Service disruption time
(SDT) measurements
The service disruption time test tool measures the time during which there is a
disruption of service due to the network switching from the active channels to the backup channels.
User-selectable triggers: all supported alarms and errors.
Measurements: last disruption, shortest disruption, longest disruption, average disruption, total disruption, and service disruption count.
Round-trip delay (RTD)
measurements
The round-trip delay test tool measures the time required for a bit to travel from the FTB-8120NGE/8130NGE transmitter back to its receiver after crossing
a far-end loopback. Measurements are supported on all supported FTB-8120NGE/8130NGE interfaces and mappings.
Measurements: last RTD time, minimum, maximum, average, measurement count (no. of successful RTD tests), failed measurement count.
APS message control and monitoring Ability to monitor and set up automatic protection switching messages (K1/K2 byte of SONET/SDH overhead).
Synchronization status
Ability to monitor and set up synchronization status messages (S1 byte of SONET/SDH overhead).
Signal label control and monitoring Ability to monitor and set up payload signal labels (C2, V5 byte of SONET overhead).
Through mode Ability to perform Through mode analysis of any incoming electrical (DSn, PDH) and optical line (OC-3/STM-1, OC-12/STM-4, OC-48/STM-16,
OC-192/STM-64, OTU1, OTU2, OTU1e and OTU2e) either transparently or intrusively.
M13 mux/demux Ability to multiplex/demultiplex a DS1 signal into/from a DS3 signal. (Note: E1 to DS3 mux/demux available with G.747 software option.)
DS1 FDL Support for DS1 Facility Data Link testing.
DS1 loopcodes Support for generation of DS1 in-band loopcodes with the availability of up to 10 pairs of user-defined loopcodes.
NI/CSU loopback emulation Ability to respond to DS1 in-band/out-of-band loopcodes.
DS3 FEAC Support for DS3 for-end alarms and loopback codewords.
DS1/DS3 auto detection Ability to automatically detect DS1/DS3 line coding, framing and test pattern.
Tandem connection
monitoring (TCM) a
Tandem connection monitoring (TCM), Option 2 b , is used to monitor the performance of a subsection of a SONET/SDH path routed via different network providers.
The FTB-8120NGE/8130NGE supports transmitting and receiving alarms and errors on a TCM link; also, transmission and monitoring of the tandem
connection (TC) trace can be generated to verify the connection between TCM equipment.
Error generation: TC-IEC, TC-BIP, TC-REI, OEI
Error analysis: TC-IEC, TC-REI, OEI, TC-VIOL
Alarm generation: TC-RDI, TC-UNEQ, ODI, TC-LTC, TC-IAIS
Alarm analysis: TC-TIM, TC-RDI, TC-UNEQ, ODI, TC-LTC, TC-IAIS
Payload block and replace Ability to terminate and analyze a specific high-order path element and replace it with a PRBS pattern on the TX side.
K1/K2 OH byte capture Ability to capture K1/K2 OH byte value transitions.
