Figure 4-20 shows voice terminal connections to the system cabinets via the SIP. Typically,
voice terminals are plugged into modular wall jacks that provide a cut-down block for
building wiring.
At the SIP, 858A Adapters provide a cut-down point for 4-pair wire runs.
An octopus cable (WP90780) from a station CP provides 25-pair connectorized cabling to
eight 4-pair modular jacks.
Each jack is terminated on the SIP by a 858A Adapter. An
octopus cable connects a maximum of eight voice terminals to a port CP.
