Part of Motorola’s globally proven Canopy platform, Canopy Lite SMs are designed to help network operators convert dial-up subscribers to broadband simply, quickly… and profitably.  The Canopy Lite SMs work in concert with the Canopy Advantage access points and deliver speeds of 512 Kbps throughput with 768 kbits burst and a maximum of 100 Kbps full duplex Committed Information Rate (CIR). The Canopy Lite SMs offer substantially lower costs with the same high performance, reliability and interference tolerance for which the Canopy system is renowned.

Easily integrated into your Canopy network, Canopy Lite SMs are highly scaleable. They are available in the 2.4, 5.2, 5.4 and 5.7 GHz frequency bands. In addition, they can be software upgraded via the Prizm element management system to add incremental throughput (to 1, 2, 4 or 7 Mbps) quickly and economically.

Canopy Lite Frequently Asked Questions (FAQ): Deploying Canopy® Lite SM throughput upgrades with Prizm 2.0

 

1) Do floating license keys require Prizm 2.0 with License Manager?

2) Can throughput upgrades be reused by moving them from one SM to another?

Yes. When a subscriber moves, downgrades, or cancels their service, the throughput upgrade can be moved to another SM preserving the software investment. This is why they are sometimes referred to as floating software licenses.

3) How are the throughput upgrades used by Prizm 2.0?

Prizm checks out a throughput upgrade when an SM registers to an AP and is authenticated by the bandwidth and authentication management functionality in Prizm. A license will only be checked out if the SM is assigned to a bandwidth that requires the throughput upgrade.

4) Can Prizm 2.0 bandwidth service plans be configured to check out a throughput upgrade based on the desired tier of service?

Yes. The bandwidth service plan feature of Prizm 2.0 gives you simplified control over which SMs in your network you will allow to use throughput upgrades. A license is only checked out if the SM needs a higher speed to perform at the requested bandwidth.

5) Can multiple Canopy Lite SM throughput upgrades be be applied to an SM?

No. Each key is an upgrade from the base 512kbps Canopy Lite SM. For example, if a floating key is used to upgrade a 512kbps Canopy Lite SM to 1Mbps and in the future needs to be upgraded to 2Mbps, the 1Mbps upgrade is replaced with 2Mbps throughput upgrade. With that said, the 1Mbps throughput upgrade can then be reused to upgrade another Lite SM to 1Mbps.

6) How do throughput upgrades work when the Lite SM goes offline? Does the license go back to the license pool or not?

Yes, it goes back to the pool, but depending on how the SM goes away, it could take a little time for this to occur. Generall,y we leverage a trap coming off the AP that indicates a registration of an SM was lost. If you don't have traps enabled on the AP and/or you have trap routing issues (such as not having the Prizm server IP set as a trap handler address in the AP), then the only way Prizm can detect this is through failed polling intervals. So if you are seeing significant delays in this, check your settings in your network.

7) Do I have to have Prizm Authentication enabled on the AP in order to use throughput upgrades?

Yes. Note that Canopy Lite throughput upgrades require authentication to be used; so if you didn't have authentication enabled, the previous statements about SM bandwidth licenses aren't valid and you wouldn't see any licenses checked out. To ensure all of this works effectively, you will need to make sure:

• AP has the Prizm server IP in the Authentication Server IP address list

• You have an AP Authentication Access floating license available for use by the AP (should see a count greater than one for this type of license in the licensing info of Prizm).

• You have a BAM server license running with Prizm (check on the About Prizm box)

• That you are running in FULL Prizm EMS mode (it is possible to have the license and configure the Prizm server NOT to run BAM functionality).

8) What do we have to configure at the AP or Prizm in order for the newly powered SMs to associate to an AP whose authentication is enabled?

You need to add the new SM into Prizm as a Provisioned item. Provisioned means it is allowed into the network. An SM doesn't have to be on the network or fully managed to be added to a Provisioned status. You can also indicate that such an item should be setup for full management once it does come on the network. See the Prizm User Guide version 3.0 (for use with Prizm 2.0) section 4.2.9, Procedure 17, Figure 39, and other related sections and materials.

9) Are the keys locked to my Prizm Server?

No. They are locked to your license manager, which means they can be used by any Prizm server or redundant BAM server on your network

10) Can I move my throughput upgrade keys to a different license server after I purchase them?

Yes. Contact Canopy Technical Support to understand the license transfer process.
