PIM2_63/B Connection Data
The PIM2_63/B provides 63 balanced or unbalanced E1 tributary interfaces
and has three pairs of 50-pin SCSI female connectors. Each connector pair
supports 21 E1 interfaces. The upper connector in each pair serves the E1
receive signals and the lower the E1 transmit signals. The tributaries and type
of signal (IN for receive, OUT for transmit) supported by each connector are
marked near the connector: IN 1-21, OUT 1-21, IN 22-42, OUT 22-42, IN
43-63, and OUT 43-63.
The following figure identifies the connector pins in each pair as seen when
looking into the connector. The tables list the pin assignment for a typical
connector pair (for unbalanced interfaces, wire A is the center (tip) conductor,
and wire B is the shield, or ring). These tables also list the color of the wire
connected to the corresponding pin in the cables offered by ECI Telecom’s
Transport Networking Division for connecting the tributary connector and a
distribution frame. The tributary numbers appearing in these tables are given
for the IN 1-21 and OUT 1-21 connectors. To obtain the correct tributary
numbers for the other connectors, interpret the numbers as representing the
number of the tributary in its group (for example, in connectors IN 22-42 and
OUT 22-42, 7 represents E1 tributary 28; in connectors IN 43-63 and OUT
43-63, 12 represents E1 tributary 57).
