INSTALLATION
Station Interconnect Panel (SIP)
The SIP is the station cross-connect field and consists of the following
equipment:
● 617A Panels
● Adapters
● 50A Fanning Strips.
617A Panel
The 617A Panel is a metal plate with keyslot holes on each side for mounting
on a backboard. (See Figure 2-2.) Each 617A Panel can hold eight 2210A2
or 858A Adapters, each of which can accommodate six connections to the
port circuits in the cabinets.
As many as five 617A Panels may be required
for a maximum size system.
The adapters snap into prepunched holes on
the 617A Panels. (Reattached spacer buttons keep adapters from touching
the metal panels.)
The cable rings located at the top of the 617A Panel route the building wiring
cables to the adapters.
Purse lock clips hold the building wiring cables in
place. The white posts at the bottom of the 617A Panel guide the wiring from
the 50A Fanning Strip to each column of adapters.
Preprinted boxes and numbers on the panel identify modular jacks for
record-keeping purposes.
Letters are marked in the boxes at the top of each
column by the installer.
The letter (A through J) and the corresponding
preprinted row number (1 through 24) identify the port jacks. For example,
Al identifies the modular jack located in column A row 1.
