11.16 RELATIONSHIPS BETWEEN THRESHOLDS FOR PPP/POS-PHY MODE
11.17 LOOPBACKS
11.18 BER SUPERVISION FOR B2/B3
11.15.2.2 Per POS-PHY Port Settings
11.15.2.3 Per CLAV Setting
Both in Rx and Tx direction the threshold at the Mapper/Demapper side (Thr1) and the
threshold at the Interface side (Thr2) must obey to: Thr1 + Thr2 < 130.
The PHAST-12P provides the following diagnostic loopbacks:
.
The PHAST-12P supports detection of the degraded signal (dDEG) and the excessive error
(dEXC) defects for both line (B2 BIP-96 in STM-4/OC-12 mode, B2 BIP-24 in STM-1/OC-3
mode) and path (B3 BIP-8).
The assumed distribution of errors needs to be configured:
• Enable/disable PHY port (shared with Rx UTOPIA). Note this setting is only evaluated on
• PHY Port address (shared with Rx UTOPIA)
• Timeslot for direct status (shared with Rx UTOPIA)
• receive line interface looped back to the transmit line interface
• transmit line interface looped back to the receive line interface
selection of a PHY.
