SDH testing at 155 STM-1622 Mb/s STM-4

PDH testing at 2 Mb/s140 Mb/s

Comprehensive, single-unit test solution

Field-portablerobust unit

  The HP 37724A is a comprehensive field portable SDH/PDH test set for applications from 2 Mb/s E1 up to 622 Mb/s STM-4. Generationanalysis of the SDH overhead, as well as embedded tributary payloads is/ provided. Payload mappings at 2, 34,140 Mb/s are includedcan be unframed, framed, or fully structured down to a 64 kb/s timeslot. Separate PDH ports at 2, 34,140 Mb/s can be configured as drop/or transmit/receive allowing for SDH/PDH cross multiplexer testing. Electrical interfaces are built-ina range of plug-in modules offer optical interfaces at 1310 nm1550 nm.

  With the HP 37724A you can verify the operation of SDH network alarms, error monitors, automatic protection switches, pointer processor,de-synchronizer circuits. Results are presented clearly on a large screen in text or graphics format.
