# E4480A Agilent Communication Analyzer Used

**Additional Features:**

-   Comprehensive SONET, ATM and T-carrier test from DS0 to OC-12
-   Auto-Setup function automatically configures the instrument to match the incoming signal
-   Trouble-Scan function identifies any alarms and errors at the push of a button
-   Extensive array of front-panel LEDs report signal status at-a-glance right across the hierarchy
-   Separate transmit and receive rates for cross-mux testing
-   Displays and controls a complete set of SONET overhead, including the 64byte path trace
-   STS-12c and STS-3c clear channel BER tests verify performance across the full bandwidth
-   Cross-cell BER test at up to 100% of bandwidth for stress testing ATM payloads
-   Cell loss, inter-arrival time and transfer delay measurements for ATM
-   Scans the incoming ATM signal and reports the bandwidths of active VPIs/VCIs
-   E1 in DS3 mapping including E1 timeslot testing
-   Drop and insert DS1/E1 from DS3 for thru mode testing
-   DS3 pulsemask measurements
-   In-depth DS1 test capability including in-band and out-of-band loopcodes
-   Tributary jitter measurements at STS-1, DS3, DS1 and E1

The portable, lightweight Agilent CERJAC 156MTS SONET Maintenance Test Set combines digital transmission testing capabilities with SONET-specific tests to meet your SONET and T-carrier applications in the field. You can use the base unit for STS-1 testing with full receive/transmit functions and you can drop and insert DS3 payloads. OC-1, OC-3 and OC-12 interfaces, or DS3, DS1 and E1 ports, can be added as required. Intermediate and longreach optical interfaces support 1310 or 1550 nm wavelengths.

Features include section, line and path error injection at user-selectable rates and SONET overhead control and monitoring. You can use the Agilent CERJAC 156MTS during SONET installation to test channel rates from DS0 to OC-12 with full demultiplexing of tributary signals. ATM is available for OC-3c and DS3 rates. Also, you can verify network synchronization and automatic protection switching.
