Pin and Signal Assignment for the PRI RJ-45 Connector

Note: For the PRI-8 and PRI-23 adapters: If you connect the CyberSWITCH to a CSU with a

different pinout than the CyberSWITCH’s PRI pinout described in the above table, you will

need a crossover converter between the CyberSWITCH and the CSU.

EXPANDER ADAPTER

The Expander adapter is used with PRI-8s to increase the number of possible connections. Each

Expander supports 8 additional connections. Up to three expander adapters can be used with one

PRI-8 to gain 8 B channel connections per Expander, creating a total of 30 possible connections per

line (with one channel is used for a data link). Only two expander adapters are needed for 23
