HARDWARE DESCRIPTION
Figure 4-26 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 (PEC 2720-05P) from a station CP provides 25-pair connectorized cabling to eight 4-
pair modular jacks.
Each jack is terminated on the SIP by an 858A Adapter. An octopus
cable connects a maximum of eight voice terminals to a port CP.
