AT&T System 25 - Manual (Page 84)

INSTALLATION
INSTALL EQUIPMENT ROOM STATION CABLING
System 25 is connected to the building (station) wiring in two stages. First,
the building wiring is connected to the Station Interconnect Panel (SIP).
Then, the octopus cables from the back of the cabinets are connected to the
SIP.
Accurate documentation during installation is essential to the performance
and maintenance of System 25 and will make initialization and administration
much easier to perform. The Voice and Data Station Records Form (Figure
2-26) traces the connection from the workstation where the voice or data
terminal is located to the SIP. Obtain this form from the Implementation
forms that the TC or TCSS has prepared for system initialization. When you
install the station wiring, enter the jack number and SIP number for each
terminal to identify each end of the cable run. Number and label the station
jacks per local practice.
As the octopus cables
each station should be are connected to the SIP, the port assignment for
added to the Voice and Data Station Records Form.
Port assignments are identified by cabinet number (1, 2, or 3), circuit pack
slot number (1 through 12), and port number (1 through 8). For example
1-10-06 or 11006 identifies port number 6 in the circuit pack located in slot
number 10 of Cabinet 1. The port number is the same as the octopus cable
leg number.
