Chapter 4 - Installing Videoconferencing Systems

If You Are Connecting to a PBX

❑Some PBXs require a crossover cable.

❑The PBX must provide the clock signal and act as the network side for layers 1, 2, and 3.

❑QSIG signaling (PSS1) is not supported. However, a PRI network interface module can be connected to a PISN through a gateway using ETSI DSS1 signaling.

Cables Used with the PRI Network Interface Module

The following cables may be used with the PRI network interface module.

❑Peripheral link cable: The peripheral link cable does not fit into a standard RJ-45 network port. You can, however, use it to connect any Polycom network interface module to the system.

❑PBX crossover cable: An RJ-45 crossover cable may be required when connecting the PRI network interface module to a PBX or other third-party network access device.

❑PRI Cable extension: You can purchase a cable adapter kit to extend the distance between your system and the PRI network interface module.

❑75 Ω coaxial adapter: The PRI E1 line termination is 120 Ω. In some areas, however, the E1 network connection is via a 75 Ω coaxial cable. The PRI network interface module does not directly support this, but you can obtain passive adapter devices from various vendors.
