The standalone option is available with all 7705 SAR versions. In addition, starting from
7705 SAR OS 5.0.R5, with the introduction of the Packet Microwave Adapter card (PMC),
supported on the SAR-8 and SAR-18, was the first step towards microwave integration. The
following key features are supported in this release of the 7705 SAR:
•
Proprietary Clock Recovery (PCR)
•
up to 4 MPR-e radios in unmanaged mode per PMC
The main radio configurations and topologies available are:
•
1+0 hop, with one MPR-e and one 7705 SAR per site
•
2x(1+0) XPIC hop, with two MPR-e (-HC or -XP) and one 7705 SAR per site

With 7705 SAR OS 6.0.R1 combined with 9500 MPR Release 4.1.0, the MPR-e and the
7705 SAR can operate as a single NE. The following new features are introduced in addition
to those in paragraph
7705 SAR and MPR-e standalone
•
up to 4 MPR-e per PMC managed as a single NE
•
Fast Fault Detection (FFD)
•
1+1 HSB with the MPT-HC V2/MPT-XP/9558HC by means of a coupling link
•
TDM2ETH (MEF 8) over an Epipe
In single NE mode, the MPR-e behaves differently from the MPR-e in standalone mode: the
MPR-e is part of the 7705 SAR as one Network Element. The MPR-e does not have a
dedicated IP address; however, all MPR-e radios connected to 7705 SAR units are reachable
using the 7705 SAR IP address using the MCT Launcher.
See the 7705 SAR OS 6.0 Software Release Notice (3HE07992000xTQZZA, available in
early 2013) and related user guides for information about the 7705 SAR.
