3.2.17.1 Microwave Link Overview
A microwave link allows a 7705 SAR-8 or 7705 SAR-18 to be connected to a 9500
MPR-e radio node. The MPR-e is the zero-footprint (outdoor) microwave solution
offered by Nokia that allows customers to migrate from TDM microwave to pure
packet microwave. The following MPR-e radio variants are supported:
• MPT-MC - Microwave Packet Transport, Medium Capacity (ODU)
• MPT-HC V2/9558HC - Microwave Packet Transport, High Capacity Version 2
(ODU)
• MPT-XP - Microwave Packet Transport, High Capacity (very high power version
of the MPT-HC V2/9558HC) (ODU)
• MPT-HQAM - Microwave Packet Transport, High Capacity (MPT-HC-QAM) or
Extended Power (MPT-XP-QAM) with 512/1024 QAM (ODU)
• MPT-HLC - Microwave Packet Transport, High-Capacity Long-Haul Cubic
(ANSI) (IDU)
A microwave link is configured on a 7705 SAR-8 or 7705 SAR-18 as a virtual port
object (not as a physical port) using the CLI command mw-link-id (for more
information on how to configure a microwave link, see Microwave Link Commands).
The supported microwave link types are 1+0 and 1+1 Hot Standby (HSB). To deploy
an N+0 link (with N ≥ 2), multiple links of 1+0 can be configured separately.
Note: Before a microwave link can be configured, the current 7705 SAR software package
that includes the MPR-e radio software must be downloaded from OLCS to the 7705 SAR-8
or 7705 SAR-18. See MPR-e Radio Software and Upgrade Management for more
information.
