Station Interconnect Panel (SIP)
The SIP is the station cross-connect field and consists of the following equipment:
● 617A Panels
●A d a p t e r s
●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.
