Microwave Link Overview

A microwave link allows a 7705 SAR-8 Shelf V2 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:

A microwave link is configured on a 7705 SAR-8 Shelf V2 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).

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 Shelf V2 or 7705 SAR-18. See MPR-e Radio Software and Upgrade Management for more information.

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.

A microwave link connection is made from ports 1 through 4 on a Packet Microwave Adapter card to an MPR-e radio using one of the methods described in the 7705 SAR Packet Microwave Adapter Card Installation Guide, ‟Delivering Data to an MPR-e Radio”. The radio can be configured in standalone mode to provide a basic microwave connection as described in Standalone Mode or in Single Network Element (Single NE) mode to provide the advanced networking capabilities described in Single NE Mode. The default configuration is Single NE mode.

When connected to an MPR-e radio, these ports, with microwave link configured, operate as Gigabit Ethernet ports and provide the same features as the other ports (ports 5 through 8), except for the following:

If a microwave link is not configured on ports 1 through 4, they provide all of the same features as the other Gigabit Ethernet ports (ports 5 through 8).
