2.8.8.2 Protection schemes with MPT-HC/MPT-HC V2
To implement the 1+1 configuration an optical cable must be connected from one MPT-HC/MPT-HC V2
to the second MPT-HC/MPT-HC V2. In
Figure 71 Ethernet port 2 of one MPT-HC/MPT-HC V2 is
connected to Ethernet port 2 of the second MPT-HC/MPT-HC V2.
N.B. In Figure 71 the two MPT are connected to two different MPT Access units, but they can also
be connected to the same MPT Access Unit.
Supported Protection types:
[1] RPS (Radio Protection Switching) Hitless for each radio direction
• RPS is implemented directly on the two MPT-HC/MPT-HC V2.
[2] EPS (Equipment Protection Switching) for the MPT-HC/MPT-HC V2
• EPS protects the MPT-HC/MPT-HC V2 and the cables connecting it to the MSS.
[3] HSB-TPS (Hot StandBy - Transmission Protection Switch)
• Spare ODU module is squelched.
