The HP 37717A transmission tester provides modular upgradeable solutions for field maintenance, installation, and commission of PDH, SDH, and ATM networks it includes jitter generation and measurements. Measurements: Error analysis to G.821, G.826 and M2100 (M550), based on bit errors and code errors (FAS, CRC4, BIP, REBE); frequency offset, jitter. Interfaces; UPDH: 0.7, 2, 8, 34, and 140 Mb/s to G.703. SPDH: 2, 8, 34, and 140 Mb/s to G.703. SDH: STM-1E, STM-l optical (1310 nm or 1550 nm) and STM-4 optical (1310 nm or 1550 nm). Multiple outputs: 3 additional PDH outputs. PDH Alarms: AIS, signal loss, pattern loss, errors, frame loss, CAS/CRC multiframe loss, remote alarm, and remote multiframe alarm. SDH Alarms: MS AIS, Path AIS, MS FERF, Path FERF, TU Loss of Pointer, TU Path AIS, TU Path FERF. SDH Payload Mapping: 2 Mb/s (TU-12), 34 Mb/s (TU-3), and 140 Mb/s as G.709. ATM User Cell Generation; Header values: Cell format, GFC, VPI, VCI, PTI, CLP. Error add: Cell header or payload. ATM OAM Cell Generation: Fault management: F4, F5, OAM cell flow, alarm AIS, and FERF. ATM Cell Receive; Cell selection: UNI/NNI, GFC, VPI, VCI, PTI, CLP. Alarms selection: VP and VC AIS and FERF, loss of pattern payload, cells. ATM Cell Analysis; OOS measurements: Mean cell rate, BIP-8, cell, and HEC errors, cell misinsertion , loss and transfer delay. ISM: Mean cell rate, BIP-8, HEC, and non-conforming cells. Jitter: Generation and measurement at 2, 8, 34, and 140 Mb/s; 155 and 622 Mb/s (0.171) plus 2 Mb/s wander and estimated frame slip measurements
