The following Ports and Protocols are used by PCS

The PCS client uses TCP ports 80, 2771 and 2777 to access the PCS server. It also needs to use TCP port 1433 to communicate with the SQL or MSDE database. The following ports are used by PCS to interface with Polycom video Endpoints:
  • Telnet Port 24 - VSX series endpoints for point to point calls
  • Telnet Port 23 - ViewStation and Viewstation SP endpoints in point to point calls
  • TCP 2773 - Default port for the application which manages the interface between PCS and iPower endpoints
    This port is configurable. See the PCS admin guide for more information.
Polycom Conference Suite uses many different protocols for monitoring and managing devices on the network. These include:
  • Telnet
  • HTTP
  • SNMP
  • XML
  • API’s
  • PING
PCS Client Architecture and Communication Communication with the PCS Server is carried out using 3 fundamental TCP/IP communication ports: HTML Port 80 for Microsoft Internet Explorer, TCP/IP Port 2771 (Can be reconfigured) for IPSQL Remote SQL Access, and TCP/IP Port 2777 (Can be reconfigured) for XML Server Communication. HTML Communication The Microsoft Internet Explorer Browser communicates with the PCS server using the standard HTML port 80. This communication is limited to user interface HTML and ASP Web pages. Bandwidth usage over this communication pipe is limited by user interaction and is not significant to overall network utilization. This communication path is not utilized when the Outlook Scheduler is invoked. This path is used for both Web Based Scheduling and Network Management. IPSQL Communication The IPSQL SQL Query Engine connects to the PCS Server via TCP/IP Port 2771. This port is opened and closed each time a remote query on the PCS Database is carried out. This port must be available through any firewall technology for all scheduling clients. The specific port may be relocated based on specific installation requirements. This communication path is utilized by all PCS Client application layer components. XML Server Communication The Server XML Communication Engine connects to the PCS Server via TCP/IP Port 2777. This port is opened and closed each time a remote query on the PCS Database is carried out. This port must be available through any firewall technology for all scheduling clients. The specific port may be relocated based on specific installation requirements. This communication path is utilized by all PCS Client application layer components. Device Communication The PCS Device Management Libraries communicate with a multitude of different IP based hardware and software devices. Each device (Video Codec, Router, Switch, Control System, Gateway, etc.) has a unique network interface (protocol, port, packet format) that may be used to monitor and control the specific device. The PCS Device Management Libraries contain implementations of Telnet, FTP, ICMP Echo, SNMP, HTTP, XML, and device unique API protocols. In order to carry out network management it is necessary that the Client computer have open access to all devices that it will be managing. Device Communication is not necessary for scheduling only Clients.All software versions
