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.
