The information in this appendix explains how to order satellite licenses and how to configure both Cisco Unified Communications Manager (Unified CM) and Cisco TelePresence System (CTS) to support satellite functionality. This appendix contains the following sections:

Cisco TelePresence over Satellite Networks

The Cisco TelePresence over Satellite Networks solution extends the reach of Cisco TelePresence to remote, tactical locations where terrestrial bandwidth is not available. This solution incorporates existing Cisco TelePresence endpoint and infrastructure products with new software releases designed to function more effectively on poor, high-delay networks.

The following features and benefits are supported:

• Relaxed latency, jitter, and packet-loss thresholds allow the Cisco TelePresence meeting application to function effectively over poor, high-delay, real-world satellite networks.
• Qualification and testing of Type 1 encryption devices with the Cisco TelePresence application enable military-grade security for Cisco TelePresence calls.
• New network and environment recommendations provide guidance for remote, tactical, and even mobile deployments of the Cisco TelePresence System (CTS).

This section contains the following information:

• Supported CTS Devices
• Supported CTS Software
• Supported Satellite Bandwidth
• Satellite Security

Supported Satellite Bandwidth

You will need a minimum of 3-MB bandwidth (at 720p, good motion handling) in a single-channel-per-carrier (SCPC) configuration over a single-hop satellite link.

Note Because the Cisco TelePresence video and audio are traveling up to the satellite and back down to an earth station, significant (500 ms or more) latency is introduced into the signal. The result is noticeable delay in the conversation. In addition, atmospheric conditions or other interference may impact satellite-link performance and introduce jitter or packet loss into the call. The result may be noticeable degradation of the video quality.

---

CTS software release 1.5 and later releases support satellite deployment configurations that significantly raise the thresholds for network warning messages and call termination. When a satellite endpoint joins a call (point-to-point or multipoint), all other endpoints in the call negotiate the new threshold setting, so no one in the call gets warning messages or gets dropped just because a satellite-based endpoint joins the call.

Ordering a Satellite License

You can order satellite licenses when you initially order your CTS, or you can purchase separate satellite licenses to upgrade an existing CTS. Note the following details when you order a satellite license:

• The product authorization key (PAK) will either be physically delivered to your location or electronically delivered via E-mail.
• Product Number:

– Physical: CTS-SATELLITE=

– Electronic: L-CTS-SATELLITE=

Loading a Satellite License

After you have received the satellite license, load it on Unified CM by following these steps:

Step 1 Load the license file into the Cisco Unified CM TFTP directory by following the steps in the “Uploading Files to the Cisco Unified CM TFTP Directory” in the Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System.

Step 2 After making sure that the license is available on your computer, log in to the Cisco Unified CM Administration page and follow these steps:

a. From the Navigation drop-down menu in the upper right corner, select Cisco Unified OS Administration and click Go .

b. Log in to Cisco Unified OS Administration .

c. From the Software Upgrades drop-down menu , select TFTP File Management and click the Upload File button. A dialog box appears.

d. Browse to find the appropriate license and upload the license. Leave the Directory field blank.

Step 3 Restart the Cisco Unified CM TFTP server and complete these steps:

a. From the Navigation drop-down menu, select Cisco Unified Serviceability and click Go.

b. Log into Cisco Unified Serviceability .

c. From the Tools drop-down menu , select Control Center - Feature Services .

d. In the Select Server box , select the TFTP server from the drop-down menu and click Go .

e. In the CM Services box, select the Cisco TFTP radio button.

f. Click Restart .

g. Repeat Step c through Step e for all TFTP servers.

Identifying the CTS Satellite Endpoints

After you have loaded the satellite license on Unified CM, identify the CTS satellite endpoints so that they can retrieve the satellite licenses.

To identify the CTS satellite endpoints using the Cisco Unified CM Administration interface:

Step 1 Log in to the Cisco Unified CM Administration page.

Step 2 From the Device drop-down menu, select Phone .

Step 3 Using the Find search fields, locate the CTS that will be used as a satellite endpoint.

Step 4 Click Reset to bring up a new dialog box, and then click Restart .

Step 5 Repeat Step 2 through Step 4 for each CTS satellite endpoint.

Enabling the Satellite Feature

After the satellite license has been loaded on Unified CM, and the CTS satellite endpoints have been identified, you are ready to enable the satellite feature using CTS command-line interface (CLI) commands. For information about using CTS CLI commands, see the Cisco TelePresence System Command-Line Interface Reference Guide.

To enable the satellite feature:

Step 1 Check to see that the satellite license is available. From the CTS CLI admin command prompt, enter the following command:

Step 2 Enable the satellite feature using the following command:

Step 3 Restart the calling services using the following command:
