Satellite Licenses for the Cisco TelePresence System
Revised: June 9, 2015, OL-21851-01
The information in this appendix explains how to order and enable satellite licenses. 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
The CTS 500, CTS 1000, CTS 1100, and CTS 1300 endpoint models are supported as the remote endpoint on the far end of a satellite link.
Other endpoint models (CTS 3000 Series and CTS 3200 Series) have not been qualified to work on the remote side of a satellite link because the bandwidth needed for these three-screen systems quickly becomes cost-prohibitive to run over satellite networks. Any Cisco TelePresence endpoint or mix of endpoints (for a multipoint call) can be used on the terrestrial side of the satellite link.
Supported CTS Software
You must be running CTS software version 1.5 or a later release on all Cisco TelePresence endpoints, Cisco TelePresence Multipoint Switches, and Cisco TelePresence Managers within your network to participate in a satellite call.
Note CTS Release Software is backward compatible up to two prior releases.
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.
For information about Cisco TelePresence service level requirements including bandwidth, latency (delay), jitter (variations in delay), and packet loss, see the
Cisco TelePresence Network Systems 2.0 Design Guide on Cisco.com.
The Cisco TelePresence application Transport Layer Security (TLS) and Secure Real-Time Transport Protocol (SRTP) encryption for signaling and media paths.
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.
– Physical: CTS-SATELLITE=
– Electronic: L-CTS-SATELLITE=
Loading a Satellite License on Unified CM
After you have received the satellite license, load it on Unified CM by following these steps:
Do not edit or change the contents of the license or it will become invalid.
Step 1 Load the license file into the Unified CM TFTP directory.
Step 2 After making sure that the license is available on your computer, log in to the Unified CM Administration interface and follow these steps:
a. From the
drop-down menu in the upper right corner, choose
Cisco Unified OS Administration
b. Log in to
Cisco Unified OS Administration interface
c. From the
Software Upgrades drop-down menu
TFTP File Management
and click the
button. A dialog box appears.
d. Browse to find the appropriate license and upload the license. Leave the
Step 3 Restart the Unified CM TFTP server and complete these steps:
a. From the
drop-down menu, choose
Cisco Unified Serviceability
b. Log into
Cisco Unified Serviceability
c. From the
Tools drop-down menu
Control Center - Feature Services
d. In the
Select Server box
, choose the TFTP server from the drop-down menu and click
e. In the CM Services box, click the
g. Repeat Step
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
Step 2 From the
drop-down menu, choose Phone.
Step 3 Using the Find search fields, locate the CTS that will be used as a satellite endpoint.
Step 4 Click
to bring up a new dialog box, and then click
Step 5 Repeat Step
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:
admin:show license status License feature is disabled Feature is currently not running
Step 2 Enable the satellite feature using the following command:
admin:set license satellite enable License for satellite feature changed to enabled
Step 3 Restart the calling services using the following command:
admin:utils service restart Calling Calling_Services Restarting...done
