Appendix B: ORIS Network Connectivity
B.1
Network Connectivity Information
There are two primary options for installing Stryker equipment, these are: 1) installing the equipment
on the customer's existing Local Area Network (LAN), and 2) installing the devices on a closed Stryker
network, which contains
only
Stryker equipment. Some Stryker products, such as ConnectSuite, will
not have full functionality (e.g., communication with desktop computers) unless the products are in-
stalled on the customer's existing network. Stryker equipment should be installed behind the custom-
er's firewall and does not require any outbound communication with the exception of SORN support
(see Appendix C for information about SORN).
It is recommended that all Stryker equipment be assigned to the same network subnet, as this will aid
in optimal performance and ease of installation.
B.1.1
Ports and Bandwidth
If the customer firewall is not H.323 compatible, a range of fixed ports will be used for Polycoms. The
default range of fixed ports follows:
Device
HDX8000
VSX8000
TCP Ports
1720, 3230 to 3243
1720, 3230 to 3239
UDP Ports
3230 to 3341
3230 to 3269
Bandwidth required for Polycoms can be dynamically set from 64 Kbps to 1920 Kbps depending on
bandwidth available on the network. The higher the bitrate, the better the picture quality (a 1080p call
requires a minimum of 1024 Kbps.)
B.1.2
Gateway/Session Border Controller (V2IU)
A common issue with H.323 is that it uses a number of ports to pass calls through the firewall. Use of
a Gatekeeper / Session Border Controller (V2IU) can enable H.460 NAT/Firewall traversal by fun-
neling the H.323 traffic into set ports, making it more suitable for passing through a firewall or NAT
setup. The V2IU sits alongside the firewall, acting as a proxy for H.323 traffic. For connections between
two locations with firewalls, you'll most likely need a V2IU at both ends, unless an H.323-compatible
firewall is being used, such as Cisco's PIX.
When using a Gatekeeper, E.164 IDs are required for each Polycom installed. These may be automati-
cally assigned or manually assigned when configuring the device.
If a V2IU traversal server Gateway is to be used, ensure that firewalls being traversed allow Polycom
systems behind them to open outbound TCP and UDP connections. Firewalls with a stricter rules
set should allow Polcyom systems to open at least the following outbound TCP and UDP ports: 1720
(TCP), 14085-15084 (TCP), 1719 (UDP), and 16386-25386 (UDP). For a broader range of require-
ments to enable firewall traversal, refer to Administrator's Guide of the respective Polycom device.
B.1.3
Bridging Services
If bridging services are to be used on the network, Stryker must be provided with a point of contact
with the bridging vendor in order to coordinate the proper configuration of equipment for compatibil-
ity.
