MPR-e and MSS-1c User Manual 3DB19901EFAA Edition 01 135
• MPR-E: Termination of 10E1 or 16E1 signals (E1 bi-directional interfaces according
ITU-T G.703 on the front panel)
• MPR-A: Termination of 16T1 signal with MSS-1c 16PDH variant (T1 bi-directional
interfaces according to ANSI T1.403/TR 62411 on the front panel)
• Encapsulation/Extraction of those PDH data flows into/from standard Ethernet
packets Inter Working Function
• Reconstruction of the original PDH Timing
• Sending/getting those std Ethernet packets to the Ethernet switch
• Communication with the Controller for provisioning and status report.
3.10.1.6 — MPT interface
The MPT Interface is the interface for one MPT: MPT-HC/HC V2/HC-HQAM/MC/XP/
XP-HQAM/9558HC.
For interconnections with MSS-1c, see MSS-1c to MPT-HC/HC-HQAM/9558HC
interconnection, MSS-1c to MPT-XP/XP-HQAM interconnection, and MSS-1c to MPT-
MC interconnection.
